Debian Installation :: GRUB Missing OS On Multi Boot

Oct 29, 2010

I just netinstalled Squeeze to a netbook with Windows7. The installation went well without any problem. Linux is also working OK. When I boot now, grub does not show Windows7. I took default settings during installation. I mean I did not do anything special. What should i do to fix it? Should I run osprober and grub-update?

Debian Installation :: GRUB Multi-boot Config Does Not Work On Physical Machines

Mar 26, 2016

I wrote a GRUB multi-boot configuration so I can boot multiple distributions and have storage space on one 32GB flash drive.

set imgdevpath="/dev/disk/by-label/multiboot"

Code: Select allmenuentry 'Debian Jessie amd64' {
        set isofile='/iso/debian-8.0.0-amd64-DVD-1.iso'
        loopback loop $isofile
        linux (loop)/install.amd/vmlinuz
        initrd (loop)/install.amd/initrd.gz
}

This works in virt-manager when I boot the physical usb device a virtual disk with a usb bus and it works flawlessly, but when I plug it into a physical machine the cdrom detects fails to mount /dev/sdb1 as fstype=iso9660.

Debian :: Multi Boot System - Grub / Boot Control

Mar 25, 2010

I have Lenny, and Jaunty Jackaope installed on the same hdd. Jaunty Jackaope was installed 2nd so it has control of grub (I don't know if that is the correct expression) I want to remove Jaunty Jackalope however I know from past experience that after I do this I will no longer be able to boot into Lenny as I will get a grub error at startup. How to I give boot/grub to Lenny so that I can remove the other operating system?

Debian :: Grub Error 22 - Multi Boot (Win XP Home And Lenny AMD64)

Sep 1, 2010

I have a dual boot computer. I seem to be having a bit of a problem with Grub lately. Every time I do any kind of update in Debian Lenny AMD 64 it borks my Grub. The first time I had to change a few lines in menu.lst (hd1,1 to hd0,1), no problem. The second time, things went downhill fast and G-Parted was giving me errors on my NTFS partitions. I had to do an XP repair, fixboot, and I had to reinstall Grub completely to the MBR.

Now, I having a "Grub Loading stage1.5. Grub loading, please wait.... Error 22". All I did was update Debian Linux and shut down. From my initial searches this is an error relating to not finding the correct partition. I have booted with a G-Part CD and it shows all my partitions. I do have a Windows XP Home boot cd if I need it. Here is my partition outline if you need it:

/dev/sda1 NTFS (Windows) flags--boot
/dev/sda2 Ext3 (Linux)
/dev/sda3 FAT32 (shared space between Windows and Linux)
/dev/sda4 extended
/dev/sda5 linux-swap

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 :: Multi HDD Dual Boot - Vista + Lucid Lynx - GRUB ?

Apr 27, 2010

I've got a machine that I'd got 9.10 on, that I've now upgraded to Lucid Lynx - and I'm having the same problem with dual boot (or lack thereof) that I was having previously.

Rough scenario is:

(Original Vista machine had)

C: Windows Vista OS + Windows software, etc.: 500GB - single NTFS partition - SATA drive

D: General dumping ground for data. 500GB SATA drive. Was single NTFS partition, now shrunk to install Ubuntu.

So is now:
- NTFS partition (containing general rubbish)
- Ubuntu / partition
- Ubuntu swap partition

... and then 3 x 1TB SATA drives making up an (Intel ICH9R) FakeRaid RAID5 array - that Windows can happily 'see' and use, but I don't care about Ubuntu having access to it or even seeing it.

Lucid Lynx is installed to /dev/sde6 (IIRC) - but when I boot the machine just boots straight into Vista.

I've done what I can to try and get GRUB correctly installed - to the point that right now I probably have it splattered just about anywhere and everywhere.

So - now - the machine boots and simply presents me with "GRUB Hard Disk Error" and stops...

I can fix this by running the Vista repair, with a fixmbr etc. and putting the MBR back to 'normal' on the first boot disk (/dev/sdd in this case). The machine then just boots straight into Vista.

...or I can boot into Ubuntu (or Vista) by booting off a Super Grub Disk (CD) and selecting "Boot Linux" (or whatever it is) - and it correctly boots Lucid Lynx from /dev/sde6

Ideally I want a proper GRUB dual boot menu - but I just seem to be getting into more and more of a mess!

Bootlog below will show what sort of mess I'm in:

General :: Multi Boot Grub - All Systems Recognized But 10.10 Will Not Boot - Cannot Locate The UUID Specified

Dec 20, 2010

Problem: I have installed two Ubuntu servers, 10.04 32-bit and 10.10 64-bit, in a multi-boot environment (also have FDOS and WinXPsp3). The 64-bit will not boot because grub can't find the UUID for the disk with the 64-bit system.

Brief Background: Installed 10.04 LTS two months ago with no problems. 10.04 is in a primary partition on hda with FDOS.

Installed 10.10 (64-bit) in a new primary partition on the same hd. The install seemed to go ok, but the MBR and the fs on the 10.04 were corrupted; could not boot. Restored drive, and rebuilt grub.

Installed 10.10 on separate hd (hdb). In grub step all OS's were recognized so I pointed the grub to hda. Grub failed to boot.

Rebuilt grub from 10.04 on hda. All systems recognized but 10.10 will not boot because it says it cannot locate the UUID specified.

Compared the grub.cfg for both systems, the UUID specified for hdb is the same. Also, when I mount the drive for 10.10 on the 10.04 system the drive UUID is consistent.

I know I must be missing some thing, but I know not what. Have searched and can't find any clues. All other OS's boot ok.

Hardware: AMD64 4GB, 2 internal IDE drives (hda and hdb), 1 internal SATA (hdc WinXP), various USB and Firewire Drives (no bootable systems).

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).

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 :: 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?)

General :: Setting Up A Multi Boot System With GRUB?

Aug 20, 2010

There are lots of OSs and Linux dists to install on your netbook, and I want to make it as easy as possible to install, remove and switch between them.

Just installing a dist and then another one after it will replace the GRUB boot screen every time, and some dists might override previous GRUB menus entirely.

On a previous machine I created a GRUB partition which chain-loads GRUB for each dist, but now I can't remember how I did it.

The hard drive is currently empty, since I started playing around with repartitioning. What is the easiest way to install GRUB to a partition? Links are welcome, but please no generic "install GRUB" guides because the ones I've found haven't been relevant to my particular situation (empty hard drive, multi boot environment, no CD/floppy)..

Ubuntu Installation :: Properly Multi-booting Grub With Windows First

Mar 5, 2010

I wanted windows to appear first in my grub2 menu so I renamed the 30_os_probe file(or whatever it felename is) to 09_os_probe so that it comes before the 10 linux file, problem is whenever these files get updated the updater is unable to find the 30_os_probe file since I renamed it and recreates it... leaving me with two versions (09 and 30) with 09 being of course outdated.

The updater also fails to run update-grub and instead attempts to update grub.cfg manually... and fails. I had to manually do a sudo update-grub.

Is there any way to fix this so its all updated automatically while leaving windows the top choice? No manual intervention required beyond clicking "install updates"?

Also, is it possible to JUST have the Windows and Ubuntu choices, no Ubuntu recovery, memtest, alternative(older) kernels for Ubuntu, etc in the grub menu?

Ubuntu Installation :: Multi Booting On Two Drives - How To Edit Grub

Apr 7, 2010

I have two hard drives windows 7 is on one of them and Ubuntu 9.10 is on the other. Both drives are 320GB, but different models of drives by Seagate. Both drives are detected by the BIOS and both drives are detected by Windows, but only one drive is detected by Ubuntu during the installation process. I had to literally disconnect the Windows drive to get Ubuntu to recognize the drive I wanted it on. Now that Ubuntu is completely installed and a new Kernel has been downloaded and installed it finally recognizes both drives as existing.

There is some kind of problem with the Installer and the original Kernel that kept it from seeing the second drive. I will literally have to manually edit Grub to get it to boot the Windows drive. How do I edit Grub? and what kind of Grub command would do the trick? I searched for "multi-boot" and literally read them all, there was one thread about multi-boot on multi-drives, but it did not fit because the Installer recognized both drives with that thread. I have to change the boot order in the BIOS to get the drive to boot that I want currently.

Fedora Installation :: Dual - Boot Into Windows 7 From GRUB - Black Screen Says "BOOTMGR" Is Missing

Apr 27, 2010

I've had Windows 7 installed for a few months now and would like to install Fedora 12 on a separate partition. I've tried this three times now, all of them ending with something wrong. The problem that exists for me now is that when I install Fedora 12 and boot up for the first time in GRUB, Fedora 12 works fine. ut when I boot into Windows 7 from GRUB, it just comes up with a black screen and says "BOOTMGR is missing; press ctrl + alt + del to restart" at the top. I don't believe that GRUB is booting into the wrong partition because I have no Windows recovery partition, just Windows 7. Also when I try and fix the Windows 7 partition with the system recovery disk, it says that the volume is corrupt every time. At this point I have everything backed up on a separate drive so I'm open to try installing Fedora 12 again even if it risks screwing up my Windows 7 partition, I would really just like to have a functioning dual boot.

Ubuntu :: Missing Grub And Dual Boot Menu - Windows Won't Boot

Jul 3, 2011

i am having a problem with my dual boot setup. I originally installed windows XP on a 100gb hard drive, from there i downloaded and burnt ubuntu off so i could install it on my 200gb hard drive. For a little bit i struggled to even get it to install because it wouldn't recognize my onboard nvidia graphics, i ended up having to get an alt boot disk and fix it with technique in this link:

[URL]

Now after the bios boot, my screen shuts off for awhile and takes me directly to the login screen for ubuntu. No Grub, no windows boot options, nothing. I tried booting windows by choosing it from the bios boot menu but all it does is hang at prompt and doesn't boot at all. I tried the live cd fix and reinstalled grub but nothing changed. What i think is happening is that it boots the Grub menu but it doesn't display it because of graphical confrontations. It hangs for about 10 seconds, the grub default time, and then turns my monitor back on to display the Ubuntu login screen.

Debian Installation :: Jessie UEFI System Boot Menu Missing?

Feb 17, 2016

I have installed Debian Jessie 8.0.3 64-bit net install on an IBM ThinkCentre. I have earlier had a dual boot Win 8 and Ubuntu 14.04 installed on the computer. When I installed Debian Jessie, I deleted the Ubuntu partitions and created new partitions from the free space. The install went fine and the Debian EFI/UEFI version of Grub was installed, but clearly at some other place, as when I boot the system, the old Ubuntu Grub pops up and of course cannot find the necessary files that it is looking for.

Fedora Installation :: Multi Boot System - Set Up The Boot Loader ?

Mar 18, 2010

I'm trying to install Fedora onto a computer that has Windows XP on the first of two SATA drives. Windows 7 is on the second drive.

I installed Fedora no problems on a 14 gig free space I created on the first drive and told it where and what my other OS's were. Fine so far. I didn't tell it to overwrite the MBR on the XP (first) drive. I took the second option which I "think" put the boot loader on the fedora partition.

All good - till I rebooted and I just saw my Windows 7 loader with my options for XP and Windows 7 but no Fedora.

So, if I overwrite the MBR on the first drive, will that mean I can't access my Windows 7 installation?

How SHOULD I set up the boot loader?

Debian Configuration :: Grub2 Multi Boot With XP ?

Jun 29, 2011

I recently upgrade my grub to grub2 and had problem to boot debian. After trying to fix it myself, I played around with grub-image-ntldr, my debian now works ok, but I cant boot my XP anymore.

Now when I try to boot XP, I got "No grldr" message. If I copy my ntldr and rename it to grldr, my XP will boot ok. So it seems that when I try to boot XP it doesn't chainload ntldr anymore, it is looking for grldr.

I tried to change "chainload +1" to "chainload /ntldr", it complains about invalid signature. Does anyone knows why my grub now using grldr instead of ntldr?

Debian :: Using VNC In A Multi-user / Multi-system Network

Mar 21, 2011

Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.

I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.

Debian Installation :: GRUB In Boot Partition?

Jun 19, 2012

I am new to Debian but have some basic experience with Linux and am currently trying to triple boot Windows 7, Fedora 16, and Debian on an HP Pavilion dv7. I have the Windows Boot Loader on my MBR because I've heard that Windows updates can cause boot issues if GRUB is installed there. This means that I've been installing GRUB in the /boot partition for each Linux distro and creating corresponding entries in the Windows boot menu.

This has worked in the past with both Fedora and Ubuntu, but I have not been able to work around it with Debian. When I choose my Debian option in the Windows boot loader, it loads GRUB but hangs after it prints "Welcome to GRUB!", and I have to restart the computer. I would like to hear what more experienced Linux users have to say both about why this isn't working for Debian and about if keeping the WIndows boot loader is the right way to go.

Also, here is my partition layout:

Partition 1: SYSTEM (HP pre-installed) (209 MB)
Partition 2: Windows Partition (472 GB)
Partition 3: Extended (160 GB)
1: /boot for Fedora (524 MB)
2: Physical Volume for other Fedora partitions (79 GB)
3: /boot for Debian (749 MB)
4: Physical Volume for other Debian partitions (80 GB)
118 GB free space
Partition 4: HP_TOOLS (HP pre-installed) (108 MB)

Debian Installation :: Grub Not Installed Properly - Cannot Boot From Anywhere

Mar 1, 2015

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...

Debian Installation :: Triple Boot On A Netbook: Grub Does Not Appear

Debian Installation :: Grub 2 Not Setting Boot Record?

Mar 21, 2011

I've been using squeeze for a year or two now, on a PC dual booting with windows xp. Not long ago I thought that, as it's now become the stable release version, I'd do a fresh install, which I've been trying to do with the first two dvds. The installation proceeds as expected, up to and including setting grub. However, although grub saysthat it has detected windows xp, and I tell it to set up the dual boot, the computer on reboot goes straight into windows xp, with no on-scrteen option shown for choosing debian.

Ubuntu Installation :: How To Configure The Multi Boot

Aug 21, 2011

I want to install Ubuntu 11.04 along my current Windows XP installation and I am trying to figure out the following:

1. How to recognize the relationship between Windows disk drive letters and the Linux disk drive indicators like /dev/sda/

2. How to configure the multi boot?

3. Where to place the Linux swap file?

4. Which Linux filesystem is the best for general use?

The specifics:

Pair of identical Seagate SATA2 80GB drives partitioned in Windows as follows:

When looking through the Ubuntu installation to be configured, I assume that drive 0 is /dev/sda where I have 3 partitions sda1, sda5, sda3. Drive 1 would be /dev/sdb with partitions sdb1, sdb5, sdb3 and I am not sure which corresponds to the Windows drive letters.

I would like to dedicate the empty drive K: for the Linux installation, swap space & data, and use minimal amount of space of drive C: for the dual boot.

Debian Installation :: UEFI GRUB Broken - Dual Boot 7.7 And Win 8.1

Dec 23, 2014

My Toshiba Satellite C870-198 has Debian 7.7 installed in UEFI mode alongside Windows 8.1. The GRUB menu no longer displays, but the machine boots straight into Windows.

I can boot into Debian or Windows from rEFInd installed on a USB stick. The rEFInd menu has the following entries:

The Debian entry actually launches the GRUB menu which was installed with Debian.

Code: Select allBoot Microsoft EFI boot (Boot Repair backup) from Basic data partition.
Boot supposed Microsoft EFI boot (probably GRUB) from Basic data partition.
Boot EFIubuntugrubx64.efi from Basic data partition.
Boot EFIdebiangrubx64.efi from Basic data partition.
Boot bootootx64.efi from Basic data partition.
Boot vmlinuz-3.2.0-4-amd64 from boot.

In an attempt to fix GRUB I executed the commands in the 'Reinstalling grub-efi on your hard drive' section of: [URL] ....

Code: Select allmount /dev/sda1 /boot/efi
... surprisingly returned:
Code: Select all$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
Did not find any restart pages in $LogFile and it was not empty.
The file system wasn't safely closed on Windows. Fixing.
Code: Select all[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"

... returned "EFI boot on HDD".

[Code] ....

... Where is Debian?

FULL HISTORY ....
=============================

The laptop came with Windows 8 preinstalled. I switched off Secure Boot and installed Ubuntu for UEFI dual boot. I recall having to use Boot Repair to get the GRUB boot manager working properly for both systems.

Recently I decided to replace Ubuntu with Debian 7.7 and first cloned the entire hard drive to a USB drive (The Clone Drive). This drive successfully boots into Ubuntu in UEFI mode.

Following this I took the opportunity to update Windows to 8.1, which broke GRUB as expected, so that the machine would only boot straight into Windows.

I installed Debian from a live USB stick in the mistaken belief that it would be bootable in UEFI mode. It did boot OK in legacy mode.

I then burned the full Debian 'DVD' image to a USB stick, booted it in UEFI mode and reinstalled Debian. In UEFI mode GRUB allowed me to boot into both Debian and Windows.

At this point I tested The Clone Drive. It was still able to boot into Ubuntu as previously, but after powering down, unplugging The Clone Drive and rebooting, the GRUB menu failed to appear and the machine booted straight into Windows. This is its current state.
