Ubuntu Installation :: 9.10 Wont Boot After Fresh Install - Raid Grub Missing ?

Mar 12, 2010

I had ubu 904 and vista installed on an 80gb drive, i had a spare 80gb drive also. I setup a raid0 config in my bios, then installed ubu9.10 onto it. All was fine until the very end, and then it said grub failed to install.

So i rebooted, and im left with a blinking cursor. How do i install grub? Ive installed ubu a few times now and never had an issue so now im lost.

Ubuntu Installation :: Fresh 10.04 Raid1 Install Will Not Boot W/o Manual Grub Input?

May 3, 2011

Followed steps 2-5 and purged/reinstalled grub now it boots as it should, NO idea where it was messed up.[URL].. I had 9.10 running in raid1 and upgraded my hardware (cpu, mb, memory etc) and wanted to do a fresh install of 10.04 to get updated. After following the various guides online such as [URL]...It begins to load grub and drops to a "grub> " shell. Which I have to do the following to get it to boot.

Code:
set root=(md1)
linux /vmlinuz root=/dev/md1 ro
initrd /initrd.img
boot

Then it boots up normally and I can use it like any other desktop. I've been over my grub.cfg and /etc/defaut/grub files and cannot find the issue. At this point I'm wondering if the fact it's a raid1 setup is keeping grub from finding it's files.

[Code]...

Ubuntu Installation :: RAID 0 And Win7 Dual Boot - Grub Cannot Install

Sep 13, 2010

I'm having serious troubles to install ubuntu-10.04.1. My raid is an hardware raid with intel chipset. Note that win7 is already installed and working with my raid. I made some space from windows, to install Ubuntu (40gb). First, I run the installer, everything seems to be fine. I choose to install Ubuntu were there is the most space free (sorry, I'm not sure about the real terms used there).

Then my partition with the vista loader appears. So the installer can see my raid, and should work fine (everything is detected correctly). But once I'm in the end of the installation (around 95%), a pop-up appears, and tells me that Grub can't install in /dev/sda and it's a fatal error. I can choose an another destination, but it doesn't seems to work.

Ubuntu Installation :: 10.10 Missing Boot Loader - Manual Install Brings To GRUB CLI?

Dec 22, 2010

I am a brand new Ubuntu user that just tried to install on an old PC using the 10.10 desktop edition.During installation, I hit an error that the bootloader could not install, and after reading about it on the forums, opted to attempt to install it manually after. I have followed the tutorial located here,[URL].. on reinstalling GRUB2 from the liveCD, which I assume means to boot with the installation CD and select try Ubuntu (given the only other option is install, which I have tried twice) everything up to step 5 in that tutorial seems to run successfully, and I am given a message it is installed, but then when I reboot the system it does not open the GRUB2 menu, rather the CLI interface, which suggests there is no grub.cfg

So I am unable to refresh at the GRUB menu because that command is not recognized by the CLI (and it may not help if I am missing files, so I might have screwed up reinstalling them in step 5, or maybe the "Try Ubuntu" terminal doesn't alter the computer like I thought?)

Ubuntu Installation :: Grub - Setup: Warning: Attempting To Install GRUB To A Partition Instead Of The MBR - Install - Lvm - Luks - Raid - Karmic Server

Mar 27, 2010

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]

If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.

Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'

Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

CentOS 5 :: Fresh Install 5.6 Won't Boot - Reboots Instantly On Selecting From Grub

May 14, 2011

I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.

Only options selected for install where 'server' and 'server gui'.

Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):

root (hd1,0)
kernel /vmlinuz-2.6.18-238.e15 ro root=/dev/VolGroup00/LogVol00 rhgb initrd /initrd-2.6.18-238.e15.img

Ubuntu Installation :: 10.04 - No Grub After Fresh Install

Jun 8, 2010

I have a new 500GB disk, with a partition with Windows XP, one with Windows 7, one for Ubuntu 10.04, one for /Home and one for swap. The systems were installed in that order. But after finishing with the Ubuntu installation, removing the CD from the drive and restarting, GRUB never showed up, and the system went straight to the Windows OS selector; the one prompting to start Windows 7 or an "Earlier version of Windows". So I can't get to Ubuntu, even though it seems it installed just fine.

As a note: just after the installation process ends and it shows the "remove CD" message, it spilled out a list of I/O errors in some sr0 device or something. But I just installed the same Ubuntu on a friend's computer and it showed a similar error list, yet his system works just fine... However, he doesn't have Windows 7, thus no OS selection screen other than GRUB. I didn't want to rush into editing the MBR or re-installing GRUB before I knew I had to do that.

Installation :: Grub Error 17 After Fresh Install

Jan 27, 2010

I have an odd problem. I custom-built a workstation:
MSI Speedster 1 mobo
2x Opteron 2352
4x DDR2 ECC 4GB
3x 150GB WD Raptor, hardware RAID 0
1x 2TB WD Green, standalone

I had Linux Mint 8 installed, but before putting the machine to real use decided to toss Windows 7 on there to see how it worked. Now I am attempting to put Mint 8 back on to get everything set up. There have been no hardware changes since I had Mint installed before.

I can successfully install, but when I reboot I get a Grub error 17. The partition table looks like:
50GB / ext4
400GB /home ext4
...
2TB /backup /ext3

Grub is installed to (hd0), which is the 450GB hardware RAID. It does not make a difference when I run the installation (and then reboot) with the 2TB drive disconnected. Thinking maybe the new ext4 format was messing with Grub, I tried:
200MB /boot ext2
50GB / ext4
400GB /home ext4
And installed again and rebooted. No dice. I'd guess Grub has issues recognizing the hardware raid, except it worked before

Ubuntu Installation :: 9.10 64, GRUB Can't Boot XP In RAID-1

Jan 12, 2010

I'm a long time windows user and it-tech but I have long felt that my geek-levels were too low so I installed Ubuntu last week (9.10 x64). Hopefully I can make it my primary OS. I have two 80GB drives in RAID-1 from my nforce raid controller, nforce 570 chipset. Then a 320 GB drive where I placed ubuntu and it's also where grub placed itself. And also a 1TB drive.

When grub tries to boot XP I get the error message: "error: invalid signature" I checked the forum as much as I could and tried a few things, but no change.

Drives sdc and sdd are the two drives in raid, they are matched exactly, but detected as different here. I really think they should be seen as one drive.

how I can make grub work as it should?

Also, if/when I need to make changes to grub, do I really have to use the live CD?

Code:
============================= Boot Info Summary: ==============================
=> Grub 1.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #1 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb
=> Windows is installed in the MBR of /dev/sdc

Ubuntu Installation :: Fresh Install Of 8.10 Over 9.10 Causes Grub 'no Such Disk' Error

Jan 27, 2010

I have a dual boot machine (Win XP + Ubuntu 9.10 on separate physical drives) which was working fine. I now want to replace the Ubuntu 9.10 with LinuxMCE which is based on Ubuntu 8.10. Using the LinuxMCE install disk, I did a fresh install of Ubuntu 8.10 over the top of Ubuntu 9.10 (repartitioning the whole drive). On reboot, I now get a Grub "no such disk" error. I have run the boot info script which produced the following RESULT.txt:

Code:
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks for

Ubuntu Installation :: 10.04 Fresh Install - No Monitor Signal / Grub Does Not Appear

Jun 22, 2010

I did a fresh install of Lucid Lynx, and now when I start up it shows a blinking cursor for a second or so and then my monitor shows an "Input signal out of range" error. The same thing has happened before, and I was able to fix it by editing the boot options in grub to include 'nomodeset'. However, this time the usual grub loading screen where I would normally press esc to edit the boot options doesn't appear. (Spamming esc doesn't seem to work either.) If it matters (which I have an odd feeling that it does) I partitioned the hard drive into an ext4 partition that mounts at / , a swap partition, and another ext4 partition that mounts at /home . I attached a screenshot of what GParted says about it.

Ubuntu Installation :: 11.04 Fresh Install / Boots Into Grub CLI And Just Sits There

May 22, 2011

My setup: a work laptop that has a corporate Win7 image, and to which I have added a few partitions to try various linux distributions. The MBR is governed by Lilo from the Slackware 13.37 installation in /dev/sda5. The MBR boots no kernel image directly, it only chainloads the boot sectors of partitions /dev/sda1, /dev/sda5, /dev/sda6 and /dev/sda7. The latter three are formatted ext4.The Win7 boot mechanism traditionally resides in /dev/sda1, and the linux distros are required to install their boot machines into their respective partitions.

What I am trying to say is, I installed Ubuntu 11.04 into /dev/sda7, and told the grub installer the same thing: install yourself into the boot sector of /dev/sda7. Kudos btw for the Ubuntu installer, it comes across as a very professional piece of software.

Ubuntu Installation :: Grub Multi Boot With Raid 0

Mar 20, 2011

There have been many postings on doing Raid 0 setups, and it seems the best way looks like softRaid, but there were some arguments for fakeRaid in dual boot situations. I've seen some posts on dual boot windows/linux in Raid 0, but I was hoping to do a multi-boot using a grub partition, with several Linux distros and Windows 7. There will also be a storage disk for data, but not in the array. From what I gather, I'll need a grub partition which can only reside on one of the two disks, one swap partition on each disk, then the rest I can stripe.

I've got two 73GB WD raptor drives to use for the OS's and programs. I'm just getting my feet wet with the terminal in linux (Ubuntu makes it way too easy to stay in GUI), and the inner workings of the OS, so I have several questions:

Is this going to be worth the effort? Obviously I'm trying to boost performance in boot and run times, but with Grub on a single drive, will I see much gain?

Does this sound like the right methodology (softRAID)? I only have two spare PCI slot's, which don't seem like they would be condusive to hardware raid, but someone who knows more could convince me otherwise.

Ubuntu Installation :: Blank Screen On Boot - GRUB With RAID

Mar 19, 2011

I am trying to install Ubuntu Server 10.10 on a computer with 5x 1.5 TB HDDs. I went through the process of partitioning the five hard drives into three partitions each:

sd*0 is a 300MB partition for /boot, RAID1, 2 active, 3 spare
sd*1 is a 500MB partition for swap, RAID1, 2 active, 3 spare
sd*2 is a 1.5TB partition for /, RAID5+LVM, 5 active, 0 spare.
md0 is the raid1 on sd*0
md1 is the raid1 on sd*1
md2 is the raid2 on sd*2

During the install, everything seemed to work fine with the formatter, but the installation ended in error. I booted into rescue mode and found that though all the drives were U (in /proc/mdstat), it was resyncing. I let this run (overnight) and the next day, jumped back in and installed the OS successfully.

However, after installing GRUB, when the installation process asked me to reboot, the system came back up with a blank screen (blank, save for a blinking cursor) and didn't move from there. I am thinking that the problem is GRUB, since I can boot into the main LVM partition via the rescue option on the install cd. Here's what bugs me:

Debian Installation :: Fresh RAID1 Wheezy Install - GRUB Just Does Not Work

Jul 26, 2014

I have a VIA Epia M 5000 system with 2 western digital 1TB NAS SATA drives connected through SATA<->IDE adapter. Everything installs and writes as expected except... grub. It never boots, after a message 'Grub loading' I always get 'error: no such disk'. I've tried numerous times and has been attemping to fix the issue for the past 2 days.

/dev/sda
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect, logical partition

/dev/sdb exactly the same
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect

/dev/md0
RAID1 of /dev/sda1 and /dev/sdb1
marked as ext4, boot point /

/dev/md1
RAID1 of /dev/sda5 and /dev/sdb5
marked as swap

update-grub2 in rescue mode generates grub.cfg with SET root=/mduuid/UUID_OF_SDA1
then after that there's search --no-floppy etc --set root=/mduuid/UUID_OF_MD0

I'm writing this from memory but simply the two uuids are different. Is this correct? I get those UUIDs to compare from blkid. All partitions are marked as bootable. grub-install /dev/sda and grub-install /dev/sdb produces no errors. grub-install /dev/md0 does not work, complains about superblocks or something similar.

Grub.cfg file contains insmod raid mdraid1x and similar lines, so that should be ok. Grub drops to rescue mode with message error: no such disk. Not device, but disk. Google finds many results for 'no such device' error, but I am not getting that error. 'ls' produces
(hd0) (hd0,msdos1) (hd1) (hd1,msdos1) ls ANY_VALID_PATH produces empty newline being printed, nothing more.

setting prefixes manually does not work, with error message 'error: file not found'. ls (hd0,msdos1)/boot/grub also produces empty line being printed. Rescue CD and auto-assemble of md0 and md1 works, the files are there, everything okay, except grub.

Ubuntu Installation :: Grub Missing - Able To Boot Into Partition

Apr 10, 2010

I had a dual boot system(WinXP and Ubuntu). But something happened and I was not able to boot into my Ubuntu partition. It gave GRUB missing error. I tried reformatting the dedicated 40 GB ubuntu partition to NTFS and again try to reinstall ubuntu. But now, when I install ubuntu through boot time install, it shows that my whole hard disk is empty( but I have windows XP on whole hdd at the moment) and do not give any other option but to use whole hdd.

Alternatively when I try to install it inside windows, then after rebooting it shows, no root file system defined error and neither gives any option to do so also ( this method worked earlier o my PC). At the moment, It still shows ubuntu and windowsXP at OS choice menu at boot time but when booting in ubuntu, it shows GRUB missing. (I don't have any ubuntu installation on my hard disk at the moment).

Debian Installation :: Grub Rescue - Will Not Boot From Mdadm RAID - No Such Disk

Sep 19, 2014

I am running a 14 disk RAID 6 on mdadm behind 2 LSI SAS2008's in JBOD mode (no HW raid) on Debian 7 in BIOS legacy mode.

Grub2 is dropping to a rescue shell complaining that "no such device" exists for "mduuid/b1c40379914e5d18dddb893b4dc5a28f".

Output from mdadm:
Code: Select all    # mdadm -D /dev/md0
    /dev/md0:
            Version : 1.2
      Creation Time : Wed Nov  7 17:06:02 2012
         Raid Level : raid6
         Array Size : 35160446976 (33531.62 GiB 36004.30 GB)
      Used Dev Size : 2930037248 (2794.30 GiB 3000.36 GB)
       Raid Devices : 14

[Code] ....

Output from blkid:
Code: Select all    # blkid
    /dev/md0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/md/0: UUID="2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb" TYPE="xfs"
    /dev/sdd2: UUID="b1c40379-914e-5d18-dddb-893b4dc5a28f" UUID_SUB="09a00673-c9c1-dc15-b792-f0226016a8a6" LABEL="media:0" TYPE="linux_raid_member"

[Code] ....

The UUID for md0 is `2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` so I do not understand why grub insists on looking for `b1c40379914e5d18dddb893b4dc5a28f`.

**Here is the output from `bootinfoscript` 0.61. This contains alot of detailed information, and I couldn't find anything wrong with any of it: [URL] .....

During the grub rescue an `ls` shows the member disks and also shows `(md/0)` but if I try an `ls (md/0)` I get an unknown disk error. Trying an `ls` on any member device results in unknown filesystem. The filesystem on the md0 is XFS, and I assume the unknown filesystem is normal if its trying to read an individual disk instead of md0.

I have come close to losing my mind over this, I've tried uninstalling and reinstalling grub numerous times, `update-initramfs -u -k all` numerous times, `update-grub` numerous times, `grub-install` numerous times to all member disks without error, etc.

I even tried manually editing `grub.cfg` to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `(md/0)` and then re-install grub, but the exact same error of no such device mduuid/b1c40379914e5d18dddb893b4dc5a28f still happened.

[URL] ....

One thing I noticed is it is only showing half the disks. I am not sure if this matters or is important or not, but one theory would be because there are two LSI cards physically in the machine.

This last screenshot was shown after I specifically altered grub.cfg to replace all instances of `mduuid/b1c40379914e5d18dddb893b4dc5a28f` with `mduuid/2c61b08d-cb1f-4c2c-8ce0-eaea15af32fb` and then re-ran grub-install on all member drives. Where it is getting this old b1c* address I have no clue.

I even tried installing a SATA drive on /dev/sda, outside of the array, and installing grub on it and booting from it. Still, same identical error.

Ubuntu Installation :: Dual-boot On A RAID-0 Array - Drops To GRUB Command Line?

May 28, 2011

I've recently had trouble reinstalling my Ubuntu system as I was getting various unusual errors as described in my old thread here. I thought it was probably something to do with my RAID-0 array which was pre-installed on my laptop from purchase being corrupted or something like that (if it's possible). I decided to simplify things for myself (not understanding RAID arrays much) so I just removed the RAID array and installed Windows and Ubuntu on the now separate hard disks. It worked fine.

I noticed quite a significant performance drop, however, with even Ubuntu boots taking longer than 30 seconds despite my laptop being both high-spec and only a few months old. Windows, as you can imagine, was dreadfully slow. I wasn't entirely convinced that this was entirely due to the loss of the RAID array - as even low-spec laptops with presumably no RAID arrays are supposed to boot Ubuntu in under 30 seconds apparently - but I read that RAID-0 arra

Ubuntu Installation :: After Update - Grub Won't Boot Says Kernel Missing

Jan 9, 2010

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.

I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

Ubuntu Installation :: Fresh Install Fails On Boot?

Sep 13, 2010

Recently freshly reinstalled ubuntu 10.04 on a new / blank hard drive and it now crashes on startup. Quick version: I have a nvidia Quadro NVS 295, it gets to the point just after the bios with the flashing dash, seemingly tries to init xserver / gdm then crashes. Keyboard lights go off but the pc stays on, and just sits there with the monitor in power saving mode. Tried in recovery mode, the blue / grey ascii terminal thing pops up for less then a second then the display crashes in the same way.

Swapping with an ATI card borrowed from elsewhere, the new install will boot quite happily. Anyone know how I can get 10.04 to boot with a nvidia quadro NVS 295? Its a bog standard card and my version of 10.04 I upgraded to on my old hard drive works fine. ts a reasonably new dell XPS 64bit pc.

Longer version:
I run 3 monitors using a PCI-e x16 NVS 295 and a PCI NVS 295. This worked great under 9.10 and 10.04. Boss gave me a solid state HD so trying to install 10.04 on that. However on my first install attempt the live CD failed to load (same problem as above, gets to init'ing the display and crashes with no output). I removed the second PCI card to run with just the 1 PCI-e x16 nvidia card, this time the live CD worked fine and I could install, but I am stuck on the boot problem. Booted into the system using the ATI card and did an update just incase something may have changes / been fixed but the issue persists.

Ubuntu Installation :: Unable To Install Grub On RAID Array

Feb 3, 2011

I'm trying to switch to a new RAID5 array but can't get it to boot. My disks:/dev/sda: new RAID member

/dev/sdb: Windows disk
/dev/sdc: new RAID member
/dev/sdd: old disk, currently using /dev/sdd3 as /

The RAID array is /dev/md0, which is comprised of /dev/sda1 and /dev/sdc1. I have copied the contents of /dev/sdd3 to /dev/md0, and can mount /dev/md0 and chroot into it. I did this:

Code:

sudo mount /dev/md0 /mnt/raid
sudo mount --bind /dev /mnt/raid/dev
sudo mount --bind /proc /mnt/raid/proc

[code]....

This completes with no errors, and /boot/grub/grub.cfg looks correct[EDIT: No it doesn't. It has root='(md/0)' instead of root='(md0)']. For example, here's the first entry:

Code:

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Ubuntu, with Linux 2.6.35-25-generic' --class ubuntu --class gnu-linu
x --class gnu --class os {

However, when I try to boot from /dev/sda, I get:

Ubuntu Installation :: Fresh Install 10.04 - Unable To Boot One Of OS (Mint)?

May 10, 2010

I admit that I am a noob - knows a little which makes it more dangerous than not knowing at all. in brief, I am unable to boot one of the OS out of 3 I have installed. Everything is fresh install on newly formatted partitions.

Here are the details:Two HDs - one is Sata and second is IDE. Win7 installed on IDE (sdb2) then Ubuntu 9.10 on Sata (sda2) and lastly Linux Mint on Sata (sda3). Everyone was on its place - that is - Ubuntu 9.10 on sda2, Linux-Mint on sda3 and Win7 on sdb2.

Future of the day was bright and promising until I upgraded online to 10.04. After that, I was only able to boot to Win7 (IDE drive - sdb2 - not sure if it changed at that point or not) but no nix OS on Sata sda2 & sda3. I downloaded 10.04 and installed from CD again on sda2. Well, now I am able to boot into Win7 and Ubuntu 10.04 but no Linux-Mint. Another interesting thing is that sda and sdb have interchanged/swapped. So now if I chcek it thru gparted or run boot script, Sata drive shows up as sdb and IDE is now sda. In another post, I read that grub2 does that and make IDE drive as the first drive and Sata drive as second. Well, I buy that but why I am unable to boot to second OS on the same Sata drive? Evidently, I am missing something and I take that it is mostly user error but please

Ubuntu Installation :: Laptop Freezes After Boot With Fresh Install 10.04?

May 22, 2010

I have a Sony Vaio PCG-k195hp laptop, in which i've installed Ubuntu 10.04. Before installation i tried the Livedisk environment to make sure that everything would work out okay.

The results were fine, ubuntu even got the onboard Wireless card working which was causing problems in windows. But after the install ubuntu has become erratic. It sometimes boots and does a lot of work but other times it'll boot and freeze as soon as i move the mouse, or even earlier. I am pretty certain the CD was not the cause as i've already used it to install 10.04 in another system and i'm writing from it right now. I got the 10.04 iso on the day it came out and thought that maybe it wasn't complete so tried updating my install, but it had an error during the update installation.

Now even the live CD won't work as it hangs in the loading screen.

Ubuntu Installation :: Disk Boot Failure After Fresh Install

Oct 16, 2010

After buying a new PC, I decided to "reorganize" my former PC as follows:Initially it has been a dual (SATA) disk dual boot PC- one disk for each OS, while XP was fully installed on a single NTFS partition. Using Gparted I shrunk the XP partition, and created some Linux partitions. I've verified that the XP partition (sda1) is bootable. Afterwards, I removed the other (former Linux) disk from the computer. While doing so, I had to temporarily disconnect cables from both drives. Finally, I fresh installed Mint 9 (Ubuntu 10.04 derivative), on my pre-prepared Linux partitions. Installation completed flawlessly, and during the install, I've noticed that GRUB2 has been installed on sda. Rebooted and got "Disk boot failure" error.

I've checked the BIOS and noticed that the (single) drive was not recognized.
I manually tested from the BIOS and located the drive as IDE3. Saving the new configuration (F10) and rebooting- the HD gain is not identified (the CMOS battery is fine- keeps time).

Booting a live CD I can see and access all above partitions.

Ubuntu Installation :: Unable To Boot WinXP After Fresh Install

Oct 23, 2010

I have some proprietory softwares installed on WinXP so it is very important for my work that it is up and running.

I performed a FULL INSTALL from the Live-CD (10.10) and installed grub on the windows partition.
Now whenever I try to select the Windows option in the Grub menu, the screen goes blank and it gets me back to the Grub menu.
