problem with root device

Post by Stupot » Wed Aug 15, 2007 5:28

I'm attempting to install Sabayon on my sisters eMachines (yuck). Anyway, the LiveDVD worked fine and the installation went fine enough. After it installed I went straight to boot into Windows XP to make sure that worked fine. Well, it didn't, I saw my mistake, went back to the LiveDVD and did the bootloader recovery option.

Long story short, I can now boot into Windows XP just fine, but when I try to boot into Sabayon I get this message....

!! Block device /dev/disk/by-uuid/7f08e225-1ac5-423e-9609-e877d91d3af1 is not a valid root device...
!! The root block device is unspecified or not detected.

Any ideas? I tried looking at the grub.conf but I couldn't see where the problem was. This installation was using Loop3.

If you look in the grub.conf file for the sabayon entry it might say something like real_root=/dev/disk/by-uuid/7f08e225-1ac5-423e-9609-e877d91d3af1
you can change it to read real_root=/dev/hda2 (or where ever your sabayon partition is).

All the best

uuid is the worst idea I've heard of. I had problems mounting my swap drive in Kubuntu with it.
