My computer won't load up video display after disabling secure boot

[IronJavelin]

I was trying to figure a way to load some old HDDs up when i found the secure boot, lucky me i didn't look into it before trying to disable secure boot and now I'm a little stuck & what I'm asking is some visuals on what i should be pressing as it may work just i cannot actually see or a quick way to reset it or at least be able to see things again

I used some of the information on this thread but i still couldn't get very much results as nothing is being displayed.  https://h30434.www3.hp.com/t5/Desktop-Boot-and-Lockup/No-monitor-input-after-disabling-secure-boot/t...
