Boot device not found

[Dotcom1098]

I downloaded Call of Duty Modern Warfare 4 and it told me I needed a BIOS update. I figured out how to update it and it said "secure boot disabled". I went back and made sure it was on only for it to not save the change for some reason. I did this several times according to Google even clearing the tpm in windows and on HP menu. Now when I boot my Omen up it shows "Secure Boot Violation" and it tells me to click submit and then takes me to "Boot Device Not Found" telling me to install operating system on my hard disk (F30) with a button that says "System Diagnostics" . These two screens are locked into a loop and I've tried spamming F10 or Esc upon rebooting the Omen and the keys are not working. I've tried turning it off, unplugging it, and draining the residual power out of it for a hard reset and trying to get F10, Esc, or Windows plus V and nothing works.

Hi @Dotcom1098 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for your patience, 

We know this isn't the answer many customers were hoping for.

Our engineers' latest advice is to follow the steps in the Technical Knowledge Base (TKB).

Resetting the TPM might fix the issue for some computers, but it can also affect Windows security settings and may require extra setup or recovery. That's why we included a warning so you can decide whether to try it.

BIOS updates are carefully tested before release. For older products that are no longer supported, we may not be able to release new BIOS updates.

At this time, this is our final recommendation. If anything changes in the future, we'll share an update through our community. 

Take care, and have an amazing day!

Regards,
