You need to be sure your motherboard can support booting off an
external USB drive - I believe most modern (~2 year old) MBs can.
I've never booted Windows from a USB device, but I imagine that it
would expect to be the first partition on the drive - just like it
does for IDE devices. If that is the case, then I would suggest that
you get familiar with restoring your bootloader in the event that
Windows or Linux (yes, Linux!) accidentally corrupts it.
This happened to me more times than I can remember. My final solution
has been to install Windows on Master of IDE 0, then change jumpers to
place it elsewhere. Then I use:
map (hd0) (hd1)
map (hd1) (hd0)
to trick Windows into thinking it's sitting on the first drive (hd0.)
Since you'll probably have Windows as the first partition, the most
common repair tool will be 'fixboot' or 'fixmbr' from the Windows
installation disk. After that repair runs, you will likely need to
edit your C:\boot.ini file to make it Linux-aware again.
Let us know what you find out!
