Alert ! /dev/disk/by-uuid/75800786-8994 does not exist. Drop to a shell
Hi everyone,
I've been using backtrack 5 r1 on a usb flash drive persistent mode for a couple of months now. Recently, I decided to use a usb 3.0 external hard drive with a flesh install of backtrack 5 .The install went well however, every time I try to boot backtrack off the external hard drive I receive this error ... Alert ! /dev/disk/by-uuid/75800786-8994 does not exist. Drop to a shell and this occurs a busybox shell comes up.. I've check the UUIDs in grub.conf and even formated and reinstalled backtrack again. I don't know how to proceed from here any help will be appreciated. |
Try checking the UUID's are right in fstab.

Here are the contains of grub.cfg and fstab.cfg.....

Please note that the UUID in the first post at the top is different since I reformat and tried to reinstall backtrack a second time. However the problem still remains the same. |
Do the UUID's match the partitions?
