Thread: Ubuntu No Longer in Grub Menu

i have 11.10 dual-booting windows 7.

decided log-in on ubuntu partition , update it, haven't used in month. updates installed, , decided restart system. however, after restarting computer, grub menu @ boot shows windows 7. oneiric installs found.

how fix this? i'd start using ubuntu again

so ran boot-info script, , these results:

sdb1 looks external hard-drive that's plugged in, , sdc1 usb drive i'm running livecd from.

code:
