Windows 10 recently updated. Received message: Secure Boot Violation Invalid Signature Detected. Now have black screen- no logo + unable to access bios. Have an Asus ROG G750JX. Please help.... I’ve removed battery & plug, waited, restarted, pressed f2, esc, del, f8, etc. but can’t get into bios.

Thanks for replying. I followed that link earlier, but can’t try any of those possible solutions since I can’t get into the bios. I can’t get a logo on the screen, and have pressed f2, del, f2+del, f8, esc, esc+f2... but can’t get beyond this black screen. Lights are on, that’s all.
