Boot up from the Ubuntu Desktop CD. Go into a terminal and type:

grub-install /dev/hda

See if that helps. If it gives you an error message, please post it here.

You can also change the Bios boot device to USB

Booting From USB HD
by MontVer / December 29, 2012 10:37 PM PST
In reply to: Bios

I have Ubuntu 12.10 on an external HD, and I've configured the boot options to boot from the USB before booting from the internal hard drive or disk. But, it still boots directly into windows 7 when I start my computer up, and when I go to manually select the ex HD to boot from, it doesn't show up as an option to choose. I'm thinking it has something to do with the external HD not mounting during rebooting but I really don't know enough about that to be sure. Any help?
