BIOS Boot on External USB HD on I:\

Using XP Home. All Windows updates.

This COMPAQ PRESARIO S5100 was working fine with a 1 GIG flash drive plugged
into the front USB port and a 75 GIG plugged into the read USB port for 2
years.

Then the last MS Updates tried to install something using the External USB
HD on I:\ but it failed. Now this PC will not boot up with either USB drive
plugged in.

The External USB HD on I:\ has to be unplugged or the BIOS sits there
waiting. As soon as it is unplugged the PB boots normal.

A restore with it UnPlugged and then a MS Update, install and restart worked
fine and dandy. But when the External USB HD on I:\ is plugged in the PC
will not restart. It hangs in the BIOS untill the External USB HD on I:\
is un-plugged.
