So, here's a crazy request.  For reasons unknown, I'm working with a BIOS which doesn't have to option to boot from USB devices, but I really want to boot off my flash drive.  The BIOS does allow me to boot from a CD (or, obviously, the hard drive, but that's not useful to me).  Is there some way I can create a CD/DVD that will allow me to then boot off my flash drive? I read this post, which is a bit beyond my level, but I think it's similar to what I want to do. Can I put Grub (or some other bootloader) on a disk, and set it to allow me to boot from USB device?
use bootable disk to redirect to flash drive
boot;usb;dual boot
