Well, I think the Question Title pretty much asks the question. I could also add that I know to keep the original HDD as a Slave drive. And isn't there something to do with the wpa.dbl file in the System32 folder?
I know that I could probably reinstall XP after formatting the 10Gb HDD, and then use a disk imaging program to copy the new C drive onto the 80Gb one. However, I would rather not do that if at all possible. Such a bother!
BTW, the 80Gb has been partitioned into two 40 Gb volumes. Will that confuse the issue?
Cheers for the help in advance!
