operating system not found

I have an Acer Aspire laptop and installed an 80 gig. Seagate HD. The failed one was an 80 gig. western digital. I have set the CMOS to install windows from the cd-rom, the CMOS are very simple and there isn't much else that can be done there. I thought that the new HD was broke so tried another one and I still get this message "no operating system found". I'm wondering if Acer has
the bios programed for just them to install the HD?
I just don't understand whats going wrong, then I put the Windows disc in the cd-rom I hear it spinning then it stops and says no operating system found. Any ideas what going wrong here?

When CDROMs age they can lose the ability to boot but work fine in other ways. I keep a laptop CDROM drive handy to test for that issue.

Not working fine.

Otherwise you could have booted your XP CD.

If you insist the drive is fine and the BIOS is set proper then the CDs are defective.
