Boot the live CD and then post the output of

Code: Select all

sudo fdisk -l
from a terminal. Also post your /boot/grub/menu.lst from Mint's partition.

Sdb seems to be a secondary drive. Sda should be the master. You won't be able to install Mint's grub to sdb and boot it directly. Is there an OS on sda?

I didn't mean you had to move the drive order. I was just trying to make sure I understood the drive order. The point I was going to make was if sda was the master drive, then the PC will try to boot from it first, and there is no link to the second drive(sdb) where Mint/grub is installed. The master drive that the PC automatically boots to first is the gateway to all the drives connected. What distro is on sda?

In that case, it would probably be easier for you to switch the drive order in the bios settings and do a quick reinstall of Mint on sdb.
