I have a Netbook Remix install on an SD card that won't boot. Grub2 in the recovery mode shows it fails finding the root files by using UUID. It's my first Grub2 install and I'm not sure how to go about debugging it. The machine boots the same version from a USB stick.
View 1 RepliesI am running Wheezy as my main OS in the first drive in my desktop. I use the 2nd drive for data. I am trying to add another OS to multiboot. When I ran grub-update in Wheezy, I am getting device letter for the root device instead of UUID in grub.cfg, in the os-prober section. Like this
Code: Select allsearch --no-floppy --fs-uuid --set=root 6ee49a8e-a619-49c7-9f66-51a5ca9a48cc
linux /boot/vmlinuz-316-x86_64 root=/dev/sdb3
initrd /boot/initramfs-316-x86_64.img
In the same file, UUID was used for the existing kernels.
Code: Select alllinux /boot/vmlinuz-3.2.0-4-686-pae root=UUID=c2eecf02-d427-4f2e-9fd0-9db61256cbac ro quiet
echo 'Loading initial ramdisk ...'
initrd /boot/initrd.img-3.2.0-4-686-pae
How can I get UUID instead of /dev/sdb3 for the 2nd OS?
So I've a computer with a lot of disks which is running Ubuntu 9.04. The setup is made od a software raid 1 array of 200 MB for use in /boot (md0), then another raid1 array of the remaining space as a unique PV for the LVM2 vg0. This vg0 is split in many lv, for /, /usr .... and swap. A few days back, one of the raid1 disk went wrong. So as the raid is built on 160Gb disks and nobody in my town sells so little disks I bought a couple of 320GB disks. The partitioning was made like the original partitions, except that the second partition is way bigger than it was. I replaced the failed disk in the arrays, and now I've an md0 of 200 MB and an md1 of roughly 150GB as it was previously and all is in sync. This replacement was made using a rescue disk (in order to be sure that the machine was not locking anything...)
So I thought it was fine. But upon reboot on the hard disks, I get a fast GRUB message "error: no such device : <UUID ending in 4ec05>. when I start the first Ubuntu entry I get the same error. So I edit the boot entry, remove the "search --no-floppy --fs-uuid --set <UUID ending in 4ec05> " and boot the damn thing. When booted I ran :

Using a M2N32-SLIDeluxe MOBO, both OS crash trying to start. It says that the timeout trying to boot from my sata device was reached.It seems that is a problem trying to boot/mount the HD by uuid, because all the other systems that does not use grub2 has problems.
View 3 Replies View RelatedFor reasons long and unique, I want to disable UUID in my recent Ubuntu 10.4 install, and use the old fashioned /dev/sda1 /dev/sdb3 etc. method. I had this "all fixed" under GRUB (pre-2) on Ubuntu 8.04 and it has served well and bug free for years. (Warning: I use old stable hardware - others may have disasters.) But with GRUB2, the task seems more complicated. (This guide me make the backups I haven't done since the fresh install 2 weeks ago.)
Is the following process complete, necessary, and accurate...
Edit the file /etc/default/grub to remove the # in the line...
#GRUB_DISABLE_LINUX_UUID="true"
... making sure to add the two " if missing .....
Copy nearly the entire /boot/grub/grub.cfg file
into /etc/grub.d/40_custom and then...
Comment out every line that says...
search --no-floppy --fs-uuid --set (etc.)
Change every line that says...
linux /boot/vmlinuz-2.x.yy-zz-generic root=UUID=(etc.) into...
linux /boot/vmlinuz-2.x.yy-zz-generic root=/dev/sda1
Edit /etc/fstab and change every instance of UUID=(etc.)
to the appropriate drive and partition e.g. /dev/sda1
edit /etc/initramfs-tools/conf.d/resume and change RESUME=UUID=(etc.)
into RESUME=/dev/sda1
Run update-grub
Do all the above, every time I do a kernel upgrade. (Is it important to do all the above before or after rebooting for an upgrade?) Am I correct, succinct, and complete in the above process? Any mistakes? Any omissions?
I'm trying to install GRUB2 on root partition under RAID 5. I tried using the alternate CD, but installation failed. Now I'm trying under the live CD and grub-install ... but I'm being told it can't find the device even though /dev/sda2 (root partition) and /dev/sda are mounted.I have 4 discs, each with a swap partition (/dev/sdX1) and a root partition (/dev/sdX2).

I was upgrading from 9.10 to 10.04 and now my HDD can't boot at all to the 2.6.34-rc6 kernel, I get dumped to the busybox shell, and when I select the 2.6.30.9 I get "The hard drive for / is not ready or not present."
I can see the drive fine with fdisk -l, /dev/sda1 is my HDD, but when booting something isn't working right. Also, is there a way to make GRUB 2 automatically show the menu so I don't have to hold down the shift key?
I posted this first to thread 'Boot problem - "Gave up waiting for root device.", (initramfs)' then realized that I should start a new thread because the problem is not the same. On boot the splash goes black and nothing happens, On a recovery boot it drops into shell BusyBox and messages indicate that the root partition cannot be found. After booting from CD Gparted GUI partition information shows no label or ssid for the root partition sda2. The data for the root partition appears to be there. how to fix this? My /home, swap, and / are on separate partitions formatted ext3. I have a recent backup only for my data. I would like to avoid having to rebuild my system from scratch.

View 2 Replies View RelatedLast night I attempted to upgrade my Ubuntu 10.10 (amd64) machine. After reboot (it installed a new kernel), the grub menu only had the memtest. Booted into a livecd and it seems that I was missing most of the files in /etc/grub.d/. Reinstalled grub-common and grub-pc didn't seem to restore the files. I ended up having to download the dpkg, expand it and copy the files manually so I could get the box generate grub.conf and boot up. I think grub may have been broken before the upgrade but exhibited the problem when it upgraded the kernel and reran upgrade-grub but I can't seem to figure out why reinstalling grub doesn't add the files back.

View 7 Replies View RelatedI'm a long time Linux user. Finally got around to upgrading my Fedora 11 system to Fedora 12 by using the 'preupgrade' tool. The upgrade appeared to go well (downloaded packages, rebooted into installer, etc). However, now that the upgrade is complete, I'm unable to boot my system.
Here's my configuration:
/dev/sda (80Gb)
200Mb /boot partition (ext3)
52Gb / partition (ext4 - managed as logical volume)
2Gb swap partition (managed as logical volume)
20Gb /spare partition (ext3 - managed as logical volume) .....
All worked fine under Fedora 11 for the last few months. Grub now presents me with 'Fedora' and 'Windows XP' boot options. The /boot/grub/menu.lst file is essentially the same as it was for Fedora 11, except for the different kernel versions, etc. The boot sequence shows the Fedora bubble (??) and gets about 80% full when the screen goes black and the message displayed is:
No root device found
Boot has failed, sleeping forever
If I boot Windows, all works fine.
Am able to boot using a SystemRescueCD disk. The disks all look okay and I can mount/modify all partitions, etc. The grub menu.lst file read as follows (sorry, typed in, not copied):
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.32.11-99.fc12.i686.PAE)
root (hd0,0) .....
I have 2 Debian OS's and wanted to put Fedora next to it.
Install went ok, but after rebooting it says: "No root device found. Boot has failed, sleeping forever."
During install from the live CD I didn't "v" the boot (efi or something?) because I thought Grub would take care of everything.
Should I just reinstall again and choose the Fedora bootloader? Won't it mess up Grub?
I insert my F14 CD and booted the computer; I see the beginning of the installation and the the screen goes black and says:
No root device found.Sleeping forever. Boot failure.
In the fstab it is written to run :
"vol_id --uuid"
and that it is a robust method...
but well there is not vol_id
command not found
I downloaded fedora 14 64 image then created a bootable flash drive and put the image on the flash drive. I rebooted and tried booting from the flash drive and that's the message I received. What do I do?

I recently installed Ubuntu Netbook Remix (10.04) on my brother's Acer Aspire One (751h) netbook, set up to dual boot with XP Professional. The initial install was successful, with both OS's booting correctly. However, after a series of updates and module builds (this machine has the Poulsbo chipset, still somewhat of a mess), Grub2 is now unable to boot XP, displaying the error "Operating system not found."
To be clear, grub works properly (aside from not booting XP), so the MBR is intact, although I've rerun grub-install to be safe. Restoring the windows MBR (using testdisk) boots XP happily, but of course ignores the ubuntu installation. I also had testdisk rebuild the NTFS boot sector, to no change - grub still doesn't work, the windows MBR does. Using the grub console, I can "root (hd0,1)" and see files on the XP partition, but "chainloader +1; boot" again fails with the same error. The ubuntu install can likewise mount the NTFS partition with no problems.
Given the fact that switching the MBR fixes the issue, I'm suspecting a Grub2 configuration problem. However, the simplicity of "root (hd0,1); chainloader +1; boot" leaves me stumped as to what that could be. Also, the error text "Operating system not found" is suspiciously identical to my BIOS's error message when attempting to boot from a non-bootable medium (as I found out while attempting to make a bootable usb stick with my mac).
instead of normal grub menu I am greeted with an:
Code:

I have been reading this but could not resolve my issue: [URL]. The problem is as follows. I got a samsung laptop and there is some kind of recovery utility installed. After installing Ubuntu I get too windows grub entries, one is called Windows Vista (loader) on /dev/sda1 and the other one is Windows 7 (loader) on /dev/sda2. The latter is correct and the first one is something that I'd rather not have active at all in the grub menu. Both of them are of course created by 30_os-prober in /etc/grub.d. I figured that I would most likely prefer a custom entry for Windows 7 and remove the x flag from 30_os-prober. I tried to create a file 50_windows7 in a described manner:
#! /bin/sh -e
echo "Adding Windows 43_custom" >&2
menuentry "Windows Vista 43_custom" {
insmod ntfs
set root=(hd0,2)
search --no-floppy --fs-uuid --set 7cecddfbecddb01e
chainloader +1 }
Unfortunately during update-grub I get following:
