Back up your menu.lst file
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak
Update your bootable drives
That should regenerate your boot drives, I'd then make sure you turn
off the bootscreen by commenting out the line "hiddenmenu" in the grub
menu.lst file and upping the time you have to select an os to boot by
taking the timeout option in the same file up to 10 at least.
This will hopefully give you the chance to see your other bootable
OS's, I had a little trouble getting my Winblows drive to be
recognized and usable and this turned the trick. Turns out it was
actually there, but the default 3 seconds wasn't enough, seems to lag
about 2-3 seconds just showing the screen so my default just kept
getting selected without my intervention.
