Most modern BIOS have the option to boot from a lot of devices, you
can check if your BIOS have options to boot from hd1, or primary
slave, whatever your BIOS call it, just enter the SETUP and check for
it.

LILO won't help you, you're installing the boot loader in a slave
disk, whatever you do, your BIOS will still call for the master (in
most cases), check your grub config twice, change it for the slave
drive (hd(1,0)?!) and change your BIOS to boot from the slave...

Or, better, change the slave/master jumpers to a config where your HD
is the master, OR EVEN BETTER, make it so your CD/DVD drives go at the
secondary IDE (if your're using IDE, I suppose so from your posts).
When different drives with different speeds are in the same IDE one
may interfer and even slow down performance of the other.
