Hi, I'm almost embarassed to ask this question, but if I
purchase XP professional Upgrade, will I have to reinstall
the previous OS, then XP in case of a crash?
If you have a regular CD of the previous system (not one of the
'restore' OEM ones that just copies back an image of the original
state), then all you need do is show the XP Setup that CD in the drive
when it asks where windows is.
If it was such a restore disk, you would have to restore it. Then Run
the CD from that system. Enter Install, change Upgrade to New Install,
then when it asks you to confirm where, hit ESC and get the chance to
select the current partition, delete it, and create a new RAW one,
going on to format it as part of the setup
This will have detected the eligibility to upgrade by that time
