There shouldn't be any mistery for this. If the BIOS is capable of
booting from a USB device but the drive where Debian has been installed
is bypassed by the BIOS, I would check that:
1/ GRUB is installed into the MBR of the USB disk.
2/ Partition where "/boot" is installed is marked with the bootable flag
(if there is no dedicated partition for "/boot", then "/" should be the
one to be marked).
3/ The system can be properly booted from an external source (i.e., using
a LiveCD of SuperGrubDisk).
