Thanks for that, but sadly my motherboard has not heard of SATA! It's PATA
all the way down....

The only SATA drive I have is an external one used for data backups through
USB, and not normally plugged in.

I've found  I can actually boot from my 'old' DVD reader (after reinstating
it in place of the new drive), so the problem appears to be associated with
the new DVD writer. I have sent it back for replacement (or to be specific,
I reported the problem and was asked to return it for replacement).

Let's see what the replacement does.
