can I boot from E:\?

[magic_plank]

Can i boot from E:\? (USB removable device) the only boot sequence options I have are:
1. Diskette drive
2. IDE CD-rom device
3. Hard Drive
4. Integrated NIC

if not, is there another way of making my computer try to boot from E:\ and if it fails, move on to A:\ and then the hard drive and CD-rom?
thanks

Unless you have an option that says Boot from removable media, your BIOS may not support booting from removable media.

Thanks for your reply, but i couldnt see that option.
I dont know if you have an autoexec.bat file on xp, but couldn't I do somethng to that to make it automatically try to boot form E:\? if there is I would need someone to tell me what to put though.
