I'm new to the multi-media OS's. Is MC2005 a stand alone install or do you need to have an underlying OS of Xp installed prior to installing MC2005? I just purchased and oem of MC2005. I just put together a mini case Antec Aria with DFI k8m800-mlvf MB, AMD Athlon 64 3700 and gig of ram and WD 300gb sata1 hd. Any tips on the installation greatlyappreciated.
