Ubuntu 10.04 problem med grub2

Hej Linux brugere

Jeg har lige geninstalleret Ubuntu 10.04. Jeg har installeret med Alternate disk og jeg har lavet en fuldstænding sletning af alle partitioner og lavet 1 partion til / og en til swap (via guiden)
Når jeg booter min PC får jeg en fejl
ALERT! /dev/disk/by-uuid/fec3f483-2619-4a55-a00e-94121a8d2294 does not exist. dropping to a shell!

busybox

(initramfs)

Hvis jeg skriver "exit" booter den op i Ubuntu (som regel. nogle gange får jeg samme fejl igen)

Jeg synes jeg kan læse at det er fordi ubuntu bruger UUID istedet for /dev/sdx
Men hvad kan jeg gøre herfra. Jeg må indrømme GRUB2 er noget mere kringlet en det jeg er vandt til.
