Ubuntu Installation :: Grub Installed On Wrong HD ?
Aug 27, 2010
I have two HDs and recently reinstalled Ubuntu.
However, I think grub may have installed to my media drive and not my main HD.
Here is the output of fdisk -l:
Code:
dev/sda1 is my media drive and I think during setup grub-install may have been automatically run on /dev/sda1. If this is the case,
1) How can I remove grub from sda1 and install it on sdb?
2) Should it be on sdb1 or sdb2?
3) Can I change the naming so my main drive is sda and my media drive is sdb?

I have a system with two hard drives: an old one with XP and Ubuntu on it, and a new one on which I have done a fresh install of XP. The BIOS is set to boot off the new drive. I have now installed Ubuntu Studio 10.04(off an alternate install disc, not a live CD)onto a partition on the new drive. The installation went fine, but it appears to have written the GRUB bootloader to the old disc. The result is that when I boot up, the system boots straight into XP off the new drive, without ever seeing GRUB. I could reset the boot order in the BIOS each time I boot according to which OS I want, but that is cumbersome; also I would like to be able to remove the old drive at some point.
What is the easiest way for me to re-install GRUB to the new disc ?

A couple weeks ago I became fed up with using Backtrack5 as a primary OS, as fun as it is, and installed Kubuntu 64-bit for AMD on a laptop with an intel chip. I didn't see an intel iso on Kubuntu's site right away, and I suppose I was too excited to try it to care. I have been having some problems with plugins working correctly, but i'm not even sure this architectural mixup is to blame for that.
To cut to the chase, should I be worried about installing kubuntu that was intended for AMD on a board with an intel chip? I figure i havent really done anything I can't easily redo yet, and if I want to reinstall, i'd like to do it before I cross that bridge!

It points to the old Fedora kernel, and needs to be directed to the pre-installed kernel. What will the new menu entry be after it loads?

Some days ago I decided to reinstall windows, of course windows wiped Grub of the MBR. No problem. I booted of the live CD (9.10) and tried to reinstall grub, I had Ubuntu 9.10 installed before windows wiped grub. I tried the following tutorial: [URL] My fdisk -l output is the following: root@ubuntu:~# fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000f2962
[Code]....
sda3 is my root partition, sda2 is the partition where all my media files are located. I mounted /dev/sda3 to /media/root and then I tried to reinstall grub with: sudo grub-install --root-directory=/media/root /dev/sda It came out with no errors, and then I restarted my computer. Grub started, but with a command line. It was the 1,97 beta-4 version. Since I'm quite unfamiliar with GRUB (or really technical linux stuff)

I recently bought a new Gateway desktop. I use mostly Ubuntu but like to boot into Windows once in a while. Have used Ubuntu as my main OS for about 3 to 4 years, dual booting. After the Ubuntu 10.04 release, I decided to throw in another hard drive into the new computer and make it dual boot.
Mistakes:
1. I did not create the Gateway Recovery Disk in Windows before installing Ubuntu.
2. Installed Ubuntu 10.04 without disconnecting the Windows 7 drive.
3. The Ubuntu install never prompted me asking where to install Grub (apparently there is an advanced menu somewhere in the install process that lets you select), and it was installed to the first drive on the PC by default, which happened to be the Win 7 drive.
This left the Windows 7 unbootable because it did not appear in the Grub menu. I did some searching and managed to install Grub on the second drive (the one with the Ubuntu install) and also managed to add Windows 7 to the Grub menu so I could boot into Windows. This last procedure added the Windows 7 option to the Grub on both drives.
I then managed to fix the Windows 7 mbr using /fixmbr and /fixboot. The problems I still have are as following. I can't create the Windows Gateway Recovery Disk in Windows. Every time I try, I get a message telling me "Hard drive configuration is not set to the factory default. Restore aborted.". I already disconnected the Ubuntu drive but get the same results. I know this one is not a Linux issue, but maybe someone had a similar issue and might be able to help.
The next problem I have is that it looks like after the las Kernel update in Ubuntu, Grub overwrote the Windows 7 mbr again. Is there a setting file somewhere that now tells Ubuntu that Grub is installed in two places and that whenever there is an update it updates both? Can I change this? I really would like to avoid re-installing Ubuntu to fix this.

I have a HP Compaq 6710b notebook with W7 on it. I want to use Ubuntu for hobby activities, but as this is a company notebook, W7 should remain intact. I decided to install Ubuntu to an external drive.I set BIOS boot order to CD-USB-HDD.I attached a 2.5" 250GB WD Passport usb hard disk and installed Ubuntu to it from the CD.As a result, the clean install doesn't boot, I get a mere grub console (normal, not rescue).
Examining the situation I learned, that during Live CD session the inner hdd is hd0 and usb drive is hd1. Grub.cfg gets compiled to use /dev/sdb.When booting from usb drive, BIOS makes it to be hd0 and inner hdd becomes hd1 so grub tries to load kernel from W7 partition (and can't find it, I wonder why? )How to fix problem? Although grub.cfg is supposed not to be edited, may I change every sdb to sda in it?

I just updated my server from Ubuntu 8.04 to 10.04 and now it cannot go past grub, at boot time, it would "give up waiting for root device", asking me to check whether I gave the right "root=..." or if I should increase the "rootdelay=..." in the command line argument and end up with the initramfs.
The machine is a Dell Poweredge 2900 with a HW RAID controller (I hope that should not matter, but just in case...). I tried to follow the instructions there to make sure grub is setup correctly, but without any luck.
Below is the output from the bootinfoscript (while running on the LiveCD). Anybody has any idea what can be the problem or what I could do to debug this ? I am running out of ideas.

I wanted to check what version of GRUB I have installed. I went to terminal and typed grub --versionI got this message back: The program 'grub' is currently not installed. You can install it by typing: sudo apt-get install grub
I am running Ubuntu 10.10 alongside windows xp pro. When I turn my pc on I have the option to boot to ubuntu or xp and at the top of the window it says that the version of grub running is "GNU GRUB Version 1.98+20100804-5Ubuntu-3" how I shold go about installing GRUB 2 or just leave it as is.

I've just installed Fedora (F13) for the first time, on a new HDD, to give myself a dual-boot system. So currently I have:
So, at the appropriate stage in the install menu, there is an option for where to install GRUB, and a drop-down to choose which drive is the primary BIOS boot drive.
However, in both cases, no other drive except my new sdc is visible. So, I can install GRUB to MBR of sdc, or to first sector of boot partition - but no option to put it to my primary boot drive MBR on sda.
Likewise, in the GRUB configuration page, if I go to Add another OS, the only option it gives me is my new Fedora install. It doesn't list the Vista OS on sda at all.
The result is that I can boot to either OS by changing the boot drive priority in BIOS.
I guess my question is this:
- is this expected behaviour from the installer, meaning that I'll need to configure GRUB manually somehow? (gulp ) or
- did I do something wrong in the install process? or
- is this some weird bug manifesting itself?

i have Vista 64Bits Ultimate installed on an 1TB hard disk whit 3 partitons I have a 2nd 160GB HD in my system which i installed Ubuntu 10.4 on. All went ok, except after the installation finished and the system rebooted it booted straight into windows, whitout ever displaying GRUB. Now i found a way to boot either system, by using the bios and setting the applicable HD to 1st device. (or something similar)
Any way on how to solve this? keeping to have to enter the BIOS to select the HD and Thus OS i want to boot aint very practical. (im currently using ubuntu BTW)

I just installed ubuntu on a partition on my laptop that already had a windows7 partition. First I had Kubuntu installed, but I decided to just try Ubuntu instead. I did things the right way when I installed Kubuntu and I could switch between OSes on reboot. Then when I installed Ubuntu I accidentally put grub on /dev/sda1 instead of /dev/sda. I didn't even notice for a while because I never felt like I needed to go back to Windows until I felt like playing starcraft 2. That's when I noticed that when the boot options screen appears and I select Windows, the screen goes black, a cursor flashes in the upper left corner for about a second, then the boot options screen reappears.
If I boot using my windows 7 cd and go into recovery, get a command prompt and type Bootrec.exe /FixMbr and Bootrec.exe /FixBoot, the options appear to complete successfully, but then when I reboot, I get a permanent flashing cursor.
If I follow that by inserting my parted magic cd and running testdisk and overwriting the mbr, I get back to the first situation where the boot options screen will appear, but the windows boot loader just returns me to the boot options screen. I can get into ubuntu, at least. Whenever I run testdisk I can't replace the boot with the backup boot because I'm pretty sure it's identical to the flawed one.

I tried upgrading to my linux to fedora 12 through updates and that completely screwed up my computer. Next I burned a disc with F12 and tried to a clean install but the installer stops after 823 packages. I tried an older FC9 image and that does not go through either. Now I'm stuck , I cannot get to my windows because I cannot get to GRUB . Is there a way to just install GRUB and boot into windows. I see that GRUB is around package # 600 or so in the installation and it does get upto that point.I just need it to finish instead of barfing on packages (no skip option in linux installer how clever!)

Upon installation of Ubuntu a while back, i was using a windows xp machine with two different harddrives. Instead of formatting the xp drive and installing Linux, i decided to install Linux on the secondary harddrive. This worked all fine and dandy until recent, when I have found my linux drive filling up near capacity. I would like to format the XP harddrive and mount it in linux to give some more disk space. The problem i have found, is that the XP drive is the drive with GRUB.

Prefactory note - I've also posted this question on the Ubuntu forum, but so far no solutions have been provided.
My system has several hard drives. The important ones are these:
Sata 1 - Fedora 12
Sata 3 - Windows 7
Slave 1 - Storage
Sata 1 was NOT installed with grub. When I switch OSs, I do it by rebooting and choosing the other drive as primary.
I downloaded an ISO of Ubuntu 9.10 (64 bit) and burned the DVD of it. I backed up Slave 1 and then booted off the Ubuntu DVD. I clicked on "Install Ubuntu", selected Slave 1, and installed onto it.
Subsequently I rebooted the machine, going into the BIOS to boot off Sata 1, so I could get my Fedora Firefox settings to replicate them under Ubuntu.
Instead of Fedora 12 booting, Grub 1.97 came up. It had 5 choices, Ubuntu, Ubuntu Repair, Memtest, some other Memtest, and Windows 7.
Subsequently I tried cracking the box and physically disconnecting Slave 1. When I rebooted Sata 1, it crashed to a grub command line. Apparently when Ubuntu installed, it infected Sata 1 with grub, even though it installed the rest of Ubuntu on Slave 1.
I really, really, REALLY need to get access to the Fedora 12 drive. It's got my work on it.
how I can get grub out of Sata 1 and regain access, or maybe reconfigure it so it recognizes the existence of Sata 1? Personally, I don't want it there; that's why I never installed it in the first place.

I hope I'm wording this issue clearly.I'd like to plug a disk (IDE or SATA) into an adapter that lets me plug it into my workstation via USB. (E.g. N82E16817153071 at newegg) It will show up as /dev/sdX where X is some arbitrary letter depending on what other disks the system happens to have.
I'd like to have a script then partition, format and copy files onto it. Then we need to install GRUB on it.
Then I will remove the disk and install it permanently into a different computer, here it will either be /dev/hda (if IDE) or /dev/sda (if SATA). However, it seems that in general when you install GRUB on a disk, it assumes it is going to be the same disk that boots??
I am first trying an IDE disk so it will be /dev/hda. I get a "GRUB Hard Disk Error" when booting it as /dev/hda rather than whetever it was on the USB adapter. I used this to install grub:
grub-install --root-directory /mnt/removable/ /dev/sdX Where X was the appropriate letter based on the USB adapter. Then I fixed /mnt/removable/boot/grub/device.map to use /dev/hda../dev/hdc instead of sda..sdc.
I haven't found much about this specific scenario I have so far on the web. I am guessing that stage1 is either attempting to find files based on what the original workstations primary disk geometry was, or it's assuming that the disk is the same location as it was when it was a "removable" one (i.e. /dev/sdX or (hd5) or whatever, when it should just be looking at (hd0).
The goal is to do this kind of installation easily and quickly, and not have to do it individually on each final computer via install CDROM or whatever, or reboot the workstation each time in order to attach the disk as the same location there, etc. (This is a manufacturing setting).

I have a dual boot windows XP/ubuntu 9.10 set up on one hard drive. Everything was working fine. The 9.10 install had been updated from 9.04. I recently had problems with the XP partition (XP basically collapsed) so I re-installed XP on the same partition it was on before. I then attempted to reinstall Ubuntu ( I decided I wanted a new 'clean' installation of Ubuntu as well). When I got to the partition function it refused to recognize that there is a Windows partition, or a previous ubuntu partition, but states 'No operating system installed' or similar, and offers the entire hard drive for installation. When I look at the partitions using Windows partition software the Windows and the ubuntu partitions are clearly in evidence. I have also tried to reinstall GRUB but it doesn't appear to exist.

I learn from a BSD magazine and installed PCBSD on my Dell notebok a single harddisk with a hope to have a triple boot. I have all the three OS, but could not find the menu.lst from /boot/grub/.... All I can find is a grub.cfg which is not editable. Someone from this forum said that menu.lst = grub.cfg.

I have an hp pavilion 15-b106ed with UEFI. I disabled secure boot and installed debian jessie form the CD1 iso (RC1 installer) burned to an USB key. Installation went smoothly, but after rebooting I get grub's terminal-like screen saying:
"GNU GRUB version 2.02 beta2-9ubuntu1. Minimal BASH-like line editing is supported... etc"
The problem is that as soon as I turn on the computer that grub screen shows up and I can't boot from USB anymore nor
access the BIOS settings, no matter how fast I press F9, F10 and such. I guess I have to tell him to boot from the USB using the grub terminal...

I accidentally installed ATI graphics drivers on an intel graphics system. They didn't appear to install properly, because upon next boot everything was fine, except for compiz and any 3d game.
compiz-check says that I've managed to get intel back as default, but I'm still missing a rendering method.
Does anyone know how to get the renderer back? I assume it has something to do with changing the kernel? I don't know how to change the kernel anyway.

I have just installed Debian and the installation went smooth (net installation). The last prompt was to specify if you want to be able to boot 3 different OS's using grub. I answered yes (I have Win7, Ubuntu and now wanted to install Debian for testing purposes). Is there any way I could manually add entry to grub for booting Debian, for instance from Ubuntu adding to menu.lst?

I installed the video drivers for my ATi 3870 and I found out the hard way it was the wrong driver, so now upon booting I can only get as far as an Ubuntu screen with some text and then my computer will restart once it reaches that point. It'll keep doing this until I turn it off, and I can't seem to get to a point in which I can get any control over it. I made a live CD but it has the same effect.
