Your post doesn't
make clear exactly what's happening. Windows
won't fully boot? The computer can't find anything
to boot? A PC doesn't ask to boot from a CD, but
if you've got a bad configuration it could show a
message like "Insert valid system disk." I've forgotten
the exact wording of that, but it means that none
of your bootable drives (usually floppy, CD, disk, in
that order) has anything bootable on them. So it's
asking you to put in a floppy or CD.
Are you familiar with the BIOS? You should have
your bootable hard disk set in the boot order. You
should also have it set as master. And make sure
all the plugs are tightly pushed in on the drives.
And note that there are two ways to set the master:
via cable select or via actual master pin position.
Either way you need the connector on the pins right
on both disks.
You also didn't mention whether you *have* a
bootable OS on the 60/40 pair. If you're setting
one disk with XP at the front of the disk as master
in the new PC then it should boot.
