Had a VIRUS that slipped thru AVG and McAfee BOTH!

Tried to go back to a previous setup after the Virus was deleted. WIN XP PRO will not completely initialize so some files are obviousy damaged.

Lucky for me I had my old Harddrive as D:\ and WIN 98se was loaded because I could no longer boot to WIN XP PRO on C:\

I reversed the boot up in the BIOS (00--->01).
Now my c: is d: and d: is c:

I was wonderig if I can copy WIN XP PRO over itself on the original harddrive or if WIN 98se will redirect the install onto it's own disk?

Basically, will I be able to direct the install (setup) to the Disk of my choice?

Thanks.
