I'm setting up my first mac and being a switcher, want to install XP and a few programs. I have a legitimate copy of XP (SP1), but I see that I need the SP2 version. I tried a couple of guides on slipstreaming (combining XP with a downloaded SP2) to make a bootable XP SP2 CD. I got an error message halfway through, which one guide explained was caused by my OEM version sold by major pc makers - thank you Dell. In reading other posts, I guess I'm confused with the Windows license and may mean I'll just go out and buy a new copy???
