I am currently running 98 and will be moving up to XP Pro shortly. I have already run the XP wizard to make sure my system will run XP and have already gotten the drivers I might need. Here is my question, I will be doing a clean install with the full version so I want to format my hard drive. This is my current setup: I have two physical hard drives, a 13 GB which is partitioned as C: and E:, I also have an 80 GB hard drive which is D:. I want to format C and E and lose the partition. What is the best way to do this. My other question is, what happens to the programs that are installed on D:. Since I will be formatting C: which is where my current OS is installed, I will be wiping out all of the registry files. Will I have to re-install everything? Hope this makes sense. This is new to me. Thanks for any help.
