Comment 34 for bug 67256

when my newly installed linux mint refused to boot most times and dropped to initramfs-shell i tried every solution i found, like rebuilding initramfs, etc.
but nothing worked.

now i found the solution for me:
i changed back the kernel parameters in grub's menu.lst.
i think, i switched the root= parameter from UUID=x to /dev/sda1 some time ago (stupid suggestion found in a wiki)
and it had not caused any errors until the kernel wouldn't find the root device anymore.
setting the root device back to an "UUID=x" entry in the default kernel options in /boot/grub/menu.lst and "sudo update-grub" made my pc booting flawless again!
(to get the UUID of your device us "sudo blkid")

just if this same thing happend to anyone out there..
