Hey - I've done some digging around, and I can only find one comment on booting to install XP Pro from a USB key. That's on the http://www.experts-exchange.com forum, which is a PAY for information one ... As Stallman says, information should be free Given that CDs only hold around 700meg, maybe 800, and that 2G USB keys are now common, I would like to set up an XP Pro installation on a USB key. Pop in the key rather than a CD, set to boot from USB-HDD, and install away, with more room for apps etc. Note - this is not actually running XP from the key - I've seen lots of examples of that. This is basically emulating a normal CD install, just sourcing it from a USB key rather than CD. Any ideas ? D.
