Hmmm, with all due respect, it sounds to me like a solution to a non-problem, actually making it worse. I mean - speaking of laptops - if you put a password protection on BIOS after having "forced" the boot from the internal disk/device you are IMHO a tadbit safer than "forcing" USB boot. Of course some laptop BIOS passwords can be worked around and of course some Operating Systems can also be "tricked" during booting, but with some care these can be patched or avoided, but allowing (actually "forcing") USB booting represents - as I see it - a much "wider" attack surface. On the other hand, you lose your keys and you cannot use the laptop while waiting on the porch for the locksmith to arrive...
