I forgot to mention, putting pagefile on USB flash drive doesn't work. I
think Windows tries to create it during boot, but USB drivers don't get
loaded so it can't access the flash drive to create it. (Probably why you
can't boot in to Windows from USB drives, I even tried enabling BIOS support
for USB drive which works for booting Linux). When I got into Windows and
checked, the pagefile never got created. But if you have another internal
hard drive or maybe even eSATA (in non-ACHI/RAID mode) you can create a
Done. I think.
