Unattended Problem

[runt]

Ok, I lost my last unattended disc somewhere in my basement. No big deal, I'll just grab my copy of XP Pro Corp. MSDN edition and slipstream SP2 the hotfixes, make the image and use it, right? Wrong, everytime I either try the image in MS Virtual PC or burn the disc in Nero I get an error saying to insert the Windows XP Pro CD into drive A:. Now on my computer, drive a is a 3.5" floppy drive so that won't work. My plain XP cd doesn't have SP2 on it, and I tried creating one with just that slipstreamed, same problem

Do I have to slipstream SP1 onto it and then slipstream SP2 onto it to get it working? I really need the disc to do a repair install of Windows on my system (so I can have it up and running properly ASAP) and this is bugging me.
