As far as (1), obviously very bios-dependent, but sometimes I've had to set
the boot order to things that didn't look like usb drives.  Sometimes they'll
have options for generic USB, sometimes USB-HDD, or even USB-FDD.  I've even
seen some bios' that have an option to have an USB drive interpreted as a
floppy (although that may be only on older systems).

For (2), is the bootloader for Foresight grub?  If so, you might be able to do
something like the following from a grub prompt (hit 'c' to get a prompt):

 # this first step may or may not be necessary, depending on the current
 # contents of your /boot/grub/device.map
 device (hd1) /dev/sdb  # supposing sdb would be your usb drive, which it
    # would be if you only have one real hard-drive
 root (hd1,0) # supposing the first partition of your usb drive is bootable
 chainloader +1
 boot

Oh, one more thing that bit me once: the first partition on your usb drive
need to be marked as bootable/active.

HTH,
