Then the CD drive is toast.

Boot the machine to the HDD, then put the CD in. If the drive works, the CD
should start by itself. If the drive is toast, then the CD won't run and the
checksum error should come up.

OK. Did that. The CD shows up. Auto-mounts and I can see what's on
it. This is really strange behavior, isn't it?

Mmm ! Delete the CD drive from the hardware list and let Windows
re-detect it.

Dirt, fluff etc can cause strange errors from a CD/DVD drive. Really it
depends upon whether you want to take it apart and clean it or spend
£30 on a new one.

Not really, it could either be the drive or the actual CD but it's
definately one or the other, most likely the drive.
Just because you can browse the contents of the CD on that machine it
doesn't follow that it will boot from the same CD, the drive needs to read
the data on the drive accurately for that.
If you have a spare drive try it, if not optical drives are very cheap.

Can you do a bad block scan on a CD drive ?

OK, I went through my software, and "Nero CD/DVD Speed 4.7.7.13"
has a "ScanDisc" option, to check for bad blocks. I dropped in
a DVD 9 disc into my drive, and as I'm typing, it is checking
for bad blocks.

There are some versions of that tool available for download.
