Not necessarily: if the BIOS supports legacy mode, Grub can see USB 
plugged disks/keys like normal HDDs. Passing down another root to Grub 
to boot from it is rather easy:

It used to work with "older", non-UEFI machine. With todays RST, UEFI 
and SecureBoot, it does not work as easily. But might be worth a try. 
This assumes that you can have a CD/DVD boot disk + USB disk connected 
to the station.

BIOS configuration may also provide an option to boot "legacy" or 
"UEFI", with UEFI being often enabled by default. Do you have access to 
BIOS/EFI configuration menus?
