Well, your computer has to be able to boot from a usb (it should be a selection in the 'BOOT' section of your computer BIOS). If it will not do that (recognize a usb as a boot device), you are stuck with CD-ROM boot.

Have you successfully created a 'Bootable' BOINCpe CD-ROM? The process is a little tricky. And you can test the CD in any working computer without screwing up that computer. If you have a 'working' CD image. That image will work with PeToUsb.

The last thing is, PeToUsb seems to have problems recognizing some USB drives (i'm using some sandisk 1 gig micro cruzers) . You have to read the info on the PeToUsb download site.

The stuff works. You just have to stick with it.
