Exactly.
The stuck Fn / F-Lock issue should be considered, but it sounds to me there are keys affected that do not typically change their function depending on that. Check it, but I have a feeling that won't be the problem here.
As for software issues, I can't even imagine what kind of a Windows problem would cause that, and the fact the boot menu is affected suggests it is not. At that point, Windows native drivers have not even been loaded. You can boot some Linux LiveCD if you want to test it completely different environment, but I wouldn't consider that necessary.
