Installing Ubuntu 7.04 to a USB Hard Drive

[Preston Smith]

Hi!

I have a Compaq Presario V2414 running XP.  I would like to install 
Ububtu on a USB drive so that I can maintain the integrity of the 
Compaq's proprietary software (for my wife to run XP) while allowing me 
to have the choice to boot to XP or to Ubuntu resident on my USB drive. 
Of course, while in Ubuntu, I would like to have access to all of the 
Compaq's features.. the Compaq's bios does not allow booting from a USB 
device.

Ideas please!

Thanks

Preston
