Amazing! New hdd installed and not only does it boot, but the BIOS / OS (?) reset the partition letters on the new hdd to as I want it!

Easy peasy. My only 'comment' on a first boot, having gone from a 500 gb that had a few partitions that were almost full, to a 1 tb with double the C: partition size (from 60 gb to 100 gb on XP) it seemed a bit slow to boot. May be that will improve as the os learns!
