Ubuntu Installation :: Non-existant UUID Number Prevents Boot Up?
Feb 1, 2010
I put my two SATA hard drives in a new computer (new mb, cpu, no pci SATA adapter, built-in nVidia graphics), and I thought everything was going well. The Mythbuntu logo came up, but the bar at the bottom did not move. It eventually dropped me out to a (initramfs) prompt.
When I used the recovery mode, this is where it had problems:
[ 4.756000]ata1:SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 5.068000]ata2:SATA link down (SSTatus 0 SControl 300)
[ 5.552000]ata3:SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 5.864000]ata4:SATA link down (SSTatus 0 SControl 300)
[Code]....
I had a SATA PCI card in my old computer, would adding that to the new system make it work? Is there someway to update the UUID numbers (I think I have done this before).

So I recently set up a fedora 13 server using software raid. Let me go over the initial install and maybe that will help explain why I'm running into problems with one of the arrays. During installation I had only 2 disks in the equipment (WD 750GB each) Partitioned them thusly:
Code:
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00062206
[Code]...

In the past month or two I've run into a strange problem where Grub gives error 18 "Selected cylinder exceeds maximum supported by BIOS". Strange because:
1) after a few tries it mysteriously starts working again without any change on my part
2) I am not running a dual boot system, which seems to be the usual cause of this problem
3) though I have SATA hard drives, I have the RAID capabilities disabled in the BIOS, which can also apparently lead to this problem.
I'm currently running lucid but it also happened once before I upgraded. It seemed to start happening not too long after I installed a new 1TB drive, though that drive is only mounted under /mnt/backup, and not anywhere else of importance, so it may be a coincidence.
Here are some specs on my machine:
BIOS is ALive NF6G-VSTA P1.80
I have 2 SATA drives (no IDE drives except DVD-ROM):
/dev/sda is a 200GB Samsung drive with two partitions
- sda1 is about 197GB and includes / (including /boot)
- sda2 is about 3GB of swap
/dev/sdb is a 1TB Western Digital Drive
- 1 partition mounted at /mnt/backup
If the problem is that I don't have a separate partition for /boot, shouldn't the error show up every time I boot, not just once in a while?

It seems today's kernel update has given a few people some difficulty - but my symptoms seem pretty unique.
* I go through GRUB normally. I 'esc' out of plymouth, and watch my services start. I get message 'mdadm: No arrays found in config file'. Don't remember seeing this before, don't have any RAID devices.
* Next, my file-system gets re-mounted in read-write mode (don't know if this is normal or not). Then, my services begin to start-up. My last service is 'crond'. All services start normally. When it gets to 'crond' the [OK] status is never reported. Visually, the screen flickers a few times, stops, then nothing happens. I can type characters though, and they do show up.
* If I then shutdown my computer by pressing the power button, the shutdown procedure begins. 'crond' shuts down successfully (indicating it started just fine), and the computer goes down normally.
* I don't believe this is an NVIDIA issue. I rescue-moded and changed my XORG.conf to the basic VESA driver to eliminate this possibility.
* Worst of all -- No older kernels work now either. They behave in the same way. When I try to boot to other run-levels, no luck either. This tempts me to think the problem might be file-system related and the re-generation of grub.conf threw something off?

I'm currently running Ubuntu (w/ GRUB) and Windows XP. I'd like to remove Ubuntu and run the recovery on Windows XP because it has started not running correctly. The computer is about 5 years old and I figured I'd just wipe it clean and start over (read: remove Ubuntu and reinstall windows via the recovery console).
I intend to follow the tutorial here: [URL]
However, I'm confused about determining the boot device number for Windows. I've run "sudo fdisk -l" and I can identify the windows drive in the list it says:
Device: /dev/sda1
Boot: *
Start: 1
End: 19352
Blocks: 155444908+
Id: 7
System: HPFS/NTFS
Am I looking for the 7, the 1, or something completely different? This is also the first partition on the list.
sda2 (id: c) is a FAT32 drive. I think this is the recovery partition included on the HP desktop.
sda3 (id:83) is Linux
sda4 (id: 82) is swap
I just need to run fixmbr.

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).

I am following a guide on how to change the boot order using a terminal on Ubuntu.
Link:[url]
At the Back Up Grub Settings part I do the " /boot/grub/menu.lst_backup " command and input my password and it gives me this:
So I hesitatingly decide to skip this part. At the Open in a Text Editor part I do the " /boot/grub/menu.lst " command in the terminal and it opens an empty file and I get a hunch...I go into /root/grub to check if the file even exists and I cannot even find the menu.Ist file anywhere.
I am guessing there may be a problem or the file is simply named differently for some reason, whats wrong or where the menu.Ist file is.

I changed something in the BIOS which causes a kernel panic, if my card is installed (Ultra ATA/133 PCI-to-ATA Host Controller). I had it working fine til a month ago, when I installed some Linux on a HD on that card. That booted fine too, and I did some disk switching. Still all was well, but yesterday I tried to boot XP (2nd IDE master)(GRUB is Ubuntu/2nd IDE slave), and XP wouldn't load. I clicked here, and clicked there, and now XP and Ubuntu boot, ONLY if the RAIDbus card is Out. Put the card in, and I get a kernel panic/lockup. This HAS to be a BIOS function - nothing is different on the disks, including GRUB menu.

Something wrong regarding grub2 (on 9.10). Yesterday everything worked fine and has done for several months. I didn't mess with anything yet when I booted from grub today it informed me that my UUID doesn't exist and that it's given up waiting for root device. I should also mention that it no longer does the 3 second count down either (not sure if thats significant). I can boot into my other linux and windows without issue. This only seems to affect all the ubuntu boot option. This is all way beyond me but I've searched around and tried the fix where you add all_generic_ide to the boot command but that didn't work. I also worked out how to check the UUID but the number look alright.
grub.cfg and blkid below:
# DO NOT EDIT THIS FILE
# It is automatically generated by /usr/sbin/grub-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub
### BEGIN /etc/grub.d/00_header ###
if [ -s /boot/grub/grubenv ]; then
have_grubenv=true
load_env
fi .....

Today I decided to install the BURG bootmenu on my computer so that I could enjoy nice, pretty graphical bootmenus instead of boring old text-based ones.I installed and configured BURG using this tutorial(after some few snafus wherein I tried to use older tutorials and went through many needless complicated steps that didn't end up working anyway).Restarted, and it worked great - except for one thing. Windows would no longer boot.It would get to the "Starting Windows" screen, then about halfway through there it would flash and restart.It wouldn't start in "Startup Repair Mode" either (the same thing happened). So, I did some frantic googling, and discovered this thread. I followed a set of instructions posted therein to install Lilo, reconfigure my MBR to Windows' liking, and reinstall Grub2.Windows booted after that.Well, I thought that the problem must have been caused by one of the numerous false starts I made while trying to get BURG installed, so I installed BURG again, set it up again, and bang - Windows wouldn't boot any more.So, I re-did the MBR with Lilo again, only this time I forgot to reinstall Grub2 (oops!) and had to boot from my LiveCD and install it thataway.At any rate, I'm fairly certain that installing BURG is what's keeping Windows from booting.

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.

I've just upgraded my wife's netbook to UNR 9.10. This seemed to go well and the netbook has been working fine since. Yesterday my daughter used the netbook with out any issues, but when my wife tried it halted during boot with:
Swap waiting for UUID: xxxxxxxxxxxxxx
After a couple of reboots it started working fine, but looking at /etc/fstab the entry for swap is different to the UUID shown in blkid Do I just update fstab with the UUID from blkid?

I'm running 64bit Lucid. I've recently had a severe problem with my softraid (5) array, and have had to recreate the array to fix it. However this now means that something is up with GRUB/initramfs, and booting times out while waiting for the root device (md0) to be ready. /boot is on a normal partition, not the raid array itself. A friend of mine has rebuilt my initramfs file with the new UUID, but now I get the message: 'Kernel panic not syncing: VFS: unable to mount root fs on unknown-block (9,0)'.So my question is either how do I sort this error, OR how do I rebuild initramfs/grub in a way that will boot?

I've got the latest version of Ubuntu on my machine.My Linux partition is ext4, so I need to use a Linux boot loader capable of booting from ext4.Also, I want to be able to use the UUID of my partition instead of specifying "/dev/sda3".Right now I'm using the Grub2 (or whatever the f*** it's called) that comes with Ubuntu. It's the ugliest boot loader you'll ever see, the configuration file is disgusting.So with that in mind, I'd like to change boot loader.Lilo would be OK but I can't seem to get it to boot from ext4.The older version of Grub was fine too but again I don't think it can boot from ext4.

After doing the proposed security updates (re)booting stalls with a message like:One or more mounts listed in /etc/fstab cannot be mounted yet /home: waiting for UUID.In the escape shell I can see from /etc/fstab that /home was mounted to /dev/sda6. But when calling blkid this device is missing.Trying to mount /home I get the error:mount: special device UUID=... does not exist.In other threads I have read that the UUID-entry for /home in /etc/fstab has to be corrected. But how do I get the correct UUID? Will making a live-CD, booting from it and then calling blkid give me the UUID for /dev/sda6?

i wanted to see the red hat side of things and do some virtualization with CentOS, so i am trying to dual boot ubuntu 10.04 LTS and CentOS 5.5. the machine is a laptop, toshiba A100 series. what I did was to create the following partitioning scheme via Ubuntu LiveCd
Code:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 19457 156288290+ 5 Extended
/dev/sda5 1 2103 16892284+ 83 Linux
/dev/sda6 2104 9988 63336231 83 Linux
/dev/sda7 9995 12623 21117411 83 Linux
/dev/sda8 12624 18800 49616721 83 Linux
/dev/sda9 18801 19457 5277321 82 Linux swap / Solaris
created an extended partition and in there have made sda5 and sda6 as / and home for ubuntu and sda7 and sda8 as / and home for CentOS. and sda9 as swap. I installed ubuntu first and then installed CentOS with no bootloader. Run sudo update-grub through ubuntu and now i have both Ubuntu and CentOS available. But when i select CentOS, i have an error which reads "invalid magic number".
I have grub2 installed, haven't downgraded or done anything to it and the ubuntu install is fresh, one week since i updated to 10.04 from scratch. I have found much contradictory stuff on google, but not something that provides a definite solution and also this post but the second command provided in the solution is one i cannot understand very well and it doesn't seem to work. what I am doing wrong here and how to make this work. I would prefer to do things via Ubuntu since debian stuff is what i am comfortable with and i am installing CentOS to learn not to do work on it.

Fresh install of 9.10. Update all. The update froze at the very end: configuring grub-pc. I let it run like that all night before settling for a reboot while the update manager was still running. (The update also raised the kernel version.) After reboot, I tried the newer kernel [2.6.31-17-generic] at the grub menu and got this error:
Quote:
udevadm trigger is not permitted while udev is unconfigured.
udevadm settle is not permitted while udev is unconfigured.
svgalib: Cannot open /dev/mem.[code].....
And, cat /proc/modules gives me a long list of modules (too much to retype for now).So my hard drive is there. maybe some errors on the / home partition [sda6] and I can get to the root directory.
FYI: MS-win XP still boots fine from grub.

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.

Alright, I have downloaded the upgrade for 10.04 and installed upgraded from my previous 8.04. Everything was working all fine until I had to reboot my pc. When I did i got some errors
Mount: Mounting none on /dev
It goes on to tell me that my UUID does not exist. Then it says
ALERT! Alert! /dev/disk/by-uuid/xxxxxxxx-xxxx-xxxx-xx$ does not exist. Dropping to a shell! It then drops to a very simple shell which has no flexibility and is very frustrating.
EDIT: This is the full error message
Mount: Mounting none on /dev
boot args cat /proc/cmdline
check rootdelay =(did the system wait long enough?)
check root =(did the system wait for the right device?)
missing modules ( cat /proc/modules)ALERT! /dev/mapper/debian-root does not exist dropping to a shell.

I 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?

I have 2 CPUs Which are Intel and AMD based. I used F9 before and didnt have any issues while I removed the hdd that I'd installed F9 on INTEL based and then put my hdd on my AMD based cpu. Well it booted and ran perfectly no issues came up.And then I've done the upgrade to F10 (clean install on INTEL). I do the same case above.But I got error msgs it said that the UUID cannot be found (I was using label on F9 fstab and worked fine).
I put back my hdd to intel based cpu and then try to edit my fstab and menu.lst (change UUID to LABEL). WOW I thought by changing UUID from fstab and menu.lst would resolve my problem but it doesnt solve anything. My devices (sda1/2/3, /boot, and /home) cannot be reconized.Well do you guys know how to change UUID to LABEL? and what exactly my problem?

Been doing some installations in a newly upgraded machine where I'm setting up two instances of 8.2 in slightly different configurations.Installing from netinst AMD64 DVD with firmware non-free. First installation goes smooth as then the second changes the UUID of the swap partition, meaning that the first then can't find it. To add insult to injury the second installation doesn't install GRUB in the MBR of the HDD.
Nothing different or special about the installation which is standard graphical with manual allocation of previously set up partitions. I don't touch the swap drive in the partitioner - just point to the correct partitions for / and /home as I want them. This is exactly as I've done before, many times.Setup asks me if I want to install GRUB in MBR and I answer "No" (because it would otherwise load in MBR of sda where I want it on sdb) then point to sdb in the next screen. Again really nothing different to what I've done dozens of times.

I just attempted to install to a USB drive, and somehow in the process, GRUB overwrote my Windows 7 bootloader on the internal disk. My work laptop is now booting into a grub recovery whenever my USB key isn't present (with error: no such device and the uuid) - and hangs on a blinking cursor whenever the key is plugged in.I'm not familiar with what my options are for grub rescue, but ls shows (hd0) (hd0,msdos2) (hd0,msdos1) (fd0)
My laptop is encrypted, so I don't have much chance of recovery unless I can get back to the windows bootloader.

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 :
