Re: iso file (win xp pro x64)
There are programs like Partitoin Magic that allow you to make multiple partitions without formatting, but I still don't feel comfortable using those.
An external HD might work, but I'd say go for an internal. You loose a good bit of performace with external drives, and it's cheaper to stay internal
Desktop: Athlon 64 3700, 1024M RAM, GF 6200 TC 256M, 2x 80G, 2x DVD-RW
Laptop: Sempron 2800, 512M RAM, Unichrome, 60G, DVD-RW
Macintosh:G4 1.33GHz, 512M RAM, Radeon 9200 32M, 40G, DVD/CDRW
They get me from 0 to 1...
