If the attacker can write a file anywhere the booter can load it,
you've lost. Perhaps most simply, that file can be a kernel with a
ramdisk filesystem including a full-fledged OS - there are many other
possibilities.
If the machine has no writable drives at all, you are probably okay.
Probably. I wouldn't want to count on it.
