Hard Disk Device Drivers Problem

Trying to install Home Basic. Running two separate internal hard disks - a
Maxtor 7L300R0 (comes up as 6L300R0 on Maxtor's site) 300gig and a no-name
40gig the computer came with. When I try to install, setup informs me that
it cannot install to either drive and gives me the option to reinstall the
drivers for either or both drives. I don't have the drivers, and I'm not
sure that's what's actually wrong here in the first place. Other details:

Doing a clean install because a) we've got XPPro and b) we found out it's a
ripped copy. Intel P4 2.8ghz processor. 1gig no-name RAM. Running the
setup program that pops up when I put the Vista disc in. 30 gigs free on the
40 gig drive, 87 gigs free on the 300 gig drive.

Help me out!
