So I wanna disable secure boot but the pc doesn't turn on when I have a display plugged in it powers but doesn't get into bios cause it beeps cause I don't have a extra fan plugged in and it doesn't beep when I have monitor plugged in I think turning off secure boot will fix this but I can't turn it off when I can see the screen

Hi

 

Secure Boot can cause problems when installing a new graphics card or using unsigned boot devices such as Linux boot media. Disconnecting a CPU fan, or in some cases, disconnecting chassis fans, will give BIOS error code.

 

Please provide specific beep codes. Providing BIOS error beep codes you hear may help to diagnose your problem.

 

Checked this site: http://h10032.www1.hp.com/ctg/Manual/c04828077.pdf  select "check for saved version".

 

Can't find any reference to BIOS error codes.
