I am unable to boot Ubuntu 10.04, with the built in boot shell giving out this error:
Gave up waiting for root device. Common problems:
— 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; ls /dev)
ALERT! /dev/disk/by-uuid/aa91b9fe-1e27-44d7-9c1b-72dd7d4e8575 does not exist.
Dropping to a shell!
BusyBox v.1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash)
Enter 'help' for list of built-in commands.
This error occurred after I updated my
2.6.32-26 version kernel and booted directly in Windows.
The rootdelay solution did not work. Is there any chance that my disk's uuid got changed (maybe by windows), I could log in to my Ubuntu earlier but after logging into windows, and rebooting I get this error. As far as backing up is concerned, do I need to even if I have separate home and workspace partitions than Ubuntu installation?
The update after which this happened was just an update (no new install) of
version 2.6.32-26. So I guess this has something to do with last update of this version of kernel. Also since it was not a new install, no new menu entry was added. By any chance may this be caused because of my rebooting in Windows after the kernel update.
Installed older kernel by chrooting through live USB, still the same problem with the kernel, so it seems the problem is not due to kernel update after all.
I have faced this problem earlier too but back then, I just considered reinstalling distribution easier (I used to distro switch a lot). But now I had configured it too far and so looking for some last resort.
Reinstalled Ubuntu. Configuration was easier this time thanks to separate home and workspace partitions. Even tough I don't need the solution of this problem just now but if you know any possible solution please post here for future benefit.
