Microsoft Windows 10 (64-bit)

I tried enabling secure boot but I get the message 'boot device not found. Try installing an operating system on your hard disk'. I've already enabled TPM because Windows 11 update told me to. But I'm having problem enabling secure boot. Help, please.

I've a Pavilion 590-p0055il desktop.

@MusashiMiyamoto -- was Windows installed with Secure Boot "on" or "off" ?

 

Did Windows boot normally before you enabled Secure Boot?
