No idea, but I'd suggest:
ensure you have the latest bios, and then do a 'reset to defaults'.
I'm pretty sure (not 100%) that Mint is not a secure boot compatible OS, so those won't work.
What is your combination of motherboard, cpu, ram, & graphics?
There should also be a key that you can hit during boot, to try a safe mode, or at least see a log of what's happening leading up to the problem.
