Drive does not exist

**dsmithnc** · June 17th, 2010

Yesterday, I tried to boot my desktop into Lucid and received this:

Gave up waiting for root device. Common Problems: e52f5315c2f
-- Boot Args (cat/proc/cmdline)
-- Check rootdelay=(did the system wait long enought?)
-- Check root= (did the system wait for the right device?)
-- Missing modules (cat/proc/modules; ls /dev)

ALERT! /dev/disk/by - uuid/56f07de1-e97f-471f-aa12-8e52f5315c2f does not exist. Dropping to shell!

BusyBox v1.13.3 (Ubunt 1:1.13.3 -1ubuntu11) built in shell (ash)
Enter 'help' for a list of commands.

(initramfs) _

Everything worked fine the day before.

I booted from a live cd and was able to access the boot drive but somehow the grub loader isn't seeing it.

At leas the data is safe...

Any suggestions?

Yes. I have found this bug. Can't boot by-uuid or by-label.
During boot does not exists /dev/disk/by-uuid
Only exists by-id and by-path
The udevd can't load blkid because it's not in $PATH.
The bug is from initramfs-tools (0.92j)
at end of /usr/share/initramfs-tools/hooks/udev it does:

Code:

copy_exec /sbin/blkid /lib/modules

and it should do:

Code:

copy_exec /sbin/blkid /sbin

Once it's corrected remember to:

Code:

update-initramfs -u

Good luck

Thanks for that. I'll give it a try as soon as I can.

Previous suggestion did not work. At best, I'll simply reinstall 10.04 to a new disk. I can still access the data.

I started the pc with the Lucid disk and then mounted sda1 and made the changes suggested to no avail.

Thanks for trying.

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and do the following:

1. Download the boot info script. There is a link in my signature.
2. Once downloaded move the boot info script to the desktop.
3. Open a terminal and run the command

Code:

sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

See here for more info on the boot info script.

Sorry for the delay, here is the results.txt contents:

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=56f07de1-e97f-471f-aa12-8e52f5315c2f ro

## should update-grub create alternative automagic boot options
## e.g. alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false

## should update-grub create memtest86 boot option

Looks like a dist-upgrade gone awry. You should have chosen to use GRUB 2 if given the choice during the upgrade process. your menu.lst looks like a strange mix of legacy GRUB and GRUB 2. Legacy GRUB uses menu. lst and USUALLY uses this designation to refer to partitions: (hdx,y) instead of UUID. I would back up any data on Ubuntu's partition that you don't want to lose and do a clean install of Lucid.
