Thread: Ubuntu won't boot, and I need to recover some important files. :(

hello there y'all,

i've been checking threads around here , trying of recommended stuff, nothing worked, hope guys can me out, since i'm kind of desperate i'm trying recover important files work due next monday.

updated system last night before going bed , turned laptop off, , when tried boot again morning, wouldn't boot. says following:

code:

mount: mounting /dev/disk/by-uuid/d7006343-535e-4b63-9c40-c1ed66cf37af on /root failed: invalid argument  mount: mounting /dev on /root/dev failed: no such file or directory  mount: mounting /sys on /root/sys failed: no such file or directory  mount: mounting /proc on /root/proc failed: no such file or directory  target filesystem doesn't have /sbin/init.  no init founf. try passing init= bootarg.

as suggested in this thread, ran ubuntu 10.04 cd , ran boot info script, , these results:

code:
