Excuse me such option in the BIOS Settings in addition to the system time is can modify, the other is gray can't modify, what method?
See someone online said delete secureboot secret key, the secret key and where is it?

CodePudding user response:

First perform the OS Optimized in the BIOS Defaults to see whether recovery, not just LoadDefault Settings,

CodePudding user response:

"Can only be closed by means of removing PK Secure Boot", "can only be opened by factory default Secure Boot", is gray Secure Boot the PK, below, choose the clean, ok, F10 save after restarting it close again, hope you can understand,
