I found the cause of this problem, which is a bug in Ubuntu only to the
extent that the problem does not occur in the installation of WIndows
or FreeBSD on my current hardware.

The original hardware was an older Chaintech motherboard with Athlon XP
and there was an Artec/Ultima DVD/CD combo drive. Ubuntu 10 ran
perfectly on this hardware. Following a failure, a Gigabyte GA-880
motherboard and Athlon II X2 was fitted.

Ubuntu 10 did not install correctly on this setup (though as mentioned
other OS did). More accurately, I believe now that it did in fact
install correctly, but at boot time the wrong information was being
supplied as to the UUID of the boot disc.

Later, I recalled that the Artec CD drive had a compatibility problem
when originally fitted in a RISC OS machine. I therefore removed the
Artec drive and fitted a new Samsung.

The problem has vanished. I conclude that there was a minor
incompatibility between the Artec drive and the IDE system on the new
motherboard, to which Ubuntu was uniquely vulnerable.
Having changed the drive I regret it is no longer possible to reproduce
the problem but I thank you for your concern.

best wishes

Martin
