I can't remember where I read it on microsoft's knowledge base, however a limitation of Windows XP is it cannot be installed to a USB hard drive and boot from that location. It can, however, be installed to a FireWire hard drive and work. IIRC there was some mention that "this may change in a future verison of Windows."

So, does anyone who is testing the beta know if it works when installed to a USB hard drive or does it still fail as it does in XP?

Thanks!

Vista needs to be installed on NFTS partition with at least 15GB of space of so.

I believe it can be shrink to 6GB afterward, but still too large to run it from USB flashdisk. Or superfast i-RAM, where I put Win XP SP2 just in 2 GB with other 2GB for swap/temp/spool/scratch etc.

So, one would really need USB hard drive just to fix on space available (:-
Haven't checked since I don't possed USB HD.
