Secure Boot option is grayed out in BIOS

[darthremus]

I recently installed Windows 11 and before updating it to 11, compatibility was everything it was supposed to be, no issue was found. But now when I try to enable the secure boot option in BIOS, I am unable to as it's grayed out. 

I have disabled the Fast Boot option from Control Panel -> Power Options -> Choose what the power button does -> Change settings that are currently unavailable and then unchecked Turn on fast startup (recommended) and saved the changes.

My legacy support is also disabled.

I have 1 SSD and 1 HDD which is GPT Partition style. 

Can anybody help me out here, please? I don't know what can I do further.

 >>Fast Boot option from Control Panel -> Power Options ....

It is recommended by MS for HDDs but not for SSDs. It creates a big hiberfil.sys that get's corrupted easily and after a while it causes a lot of trouble. Switch that off (!) in the cmd (admin) command:

powercfg /h off

2. Secure Boot in BIOS

when an option is greyed out it usually indicates that you have to change certain settings before you can activate it. (see manual)

It is also possible that you don't have the administrative  "rights" to make the change. 

Try these steps
Write down a simple password on a piece of paper
go to Security Tab
Set supervisor password
Enter New password
Confirm new password

activate secure boot (if possible)

go to Set supervisor password again

enter current password
enter new password (leave it blank!)
confirm new password (leave it blank!)

I solved this issue by going to BIOS, then System Configuration, then Boot Options, and clicking on Load HP Factory Default Keys, which then removed the gray color from Secure Boot. Finally, its enabled.
