Solved issue
This is a reference to a list of Machine Owner Keys (MOKs), which are cryptographic keys that are associated with Shim. Secure Boot requires that boot loaders be signed with a key to verify the binary's authenticity. A few public keys are stored in the computer's firmware or NVRAM; but the only keys guaranteed to be stored in this way belong to Microsoft, which has rules about what it will sign. To make a long story short, most Linux distributions use a program called Shim (shimx64.efi, normally), which is signed by Microsoft and that adds a new key for the Linux distribution that released that version of Shim
For ASUS it use to be
Then you should was able to boot on the USB key to reinstall the system. During installation, you may need to set a "Secure Boot" password
For ASUS it use to be
- Go to Bios (tap F2 at startup)
- Advanced mode (F7)
- Security tab > Security/Secure Boot > Key Management
- From there, delete all the security keys and reset them to factory settings.

Yea I figured that out, but now I can’t get into the bios
Try pressing the Fn button and the F2 button when you turn the power on. You'll also want to be patient.
I this doesn't work, it's quite likely a hardware issue and not something we can repair. I hope it's not hardware, but the directions from ASUS themselves say to press and hold the F2 button.
Anyhow, try it with the Fn button held as well and keep the button pressed for a bit.

you may also want to reach out to ASUS support if the laptop is under warranty --> https://www.asus.com/us/supportonly/gl553vd/helpdesk_warranty/
Yeah if I use the fn button it just boots normally, think it might be a hardware issue
That's horrible. At that level, if it's hardware, it's not something you'll likely be able to fix. I suppose there's a slim chance that it's RAM but it sounds more like an actual BIOS corruption type of issue.
You might be able to take the device apart to see if there's a jumper to clear current BIOS settings - or a small cell battery that can be disconnected. Those would hopefully reset the BIOS to factory defaults. If it's a corruption issue, that might work.
I doubt it'd be recognized that early in the boot process, else I'd suggest (as a shot in the dark) trying an external keyboard. I mean, after all, what if it's actually the F2 button that died?
I just tried the external keyboard, no luck ;_; I’ve been trying to take it apart but there’s one screw that’s completely stuck and it looks like either I have to break the back plate or drill it out, is there like a cmos battery in laptops that I can use to reset the bios?

Yes, there is a cmos battery.
If you are able it may be an idea to replace the battery.
They are usually a CR2032 .....but check first

Usually, yes. Some will have a germanium capacitor or similar but that's pretty rare these days. There may also be a special jumper you can remove for a few seconds and that will reset things.
As Condo suggests, replace it while you're in there. They're only a couple of bucks.
At this point, I'm going to suggest hitting up a video site, such as YouTube, to find a repair video for your laptop model. You can also try just using regular web pages but video seems convenient for this. Someone has taken that device apart and will make it easier for you to do so. Laptops can be pretty tricky to take apart at times - though your device may be quite simple.
While you're in there, take a look around. Look for things that stand out, like a leaky capacitor. Those are harder to repair but not impossible - if you have the tools and patience.
I picked up a CR2032 for my HP Stream 11 then opened it up only to find the original battery was a CR2016. Same diameter, same voltage, half as thick. Also apparently half the lifetime - no wonder it went dead at only a few years old! The laptop now has a CR2032 in it, so it will probably outlive me.
Ayt thanks for the help will give a try
Yea I’m gonna try change the battery and give it a try
I removed the ram and put it back in and it didn’t work but I changed the slot and the bios came up, I’m so happy it’s not a hardware issue
Got the bios working and this worked thanks for the very well detailed instructions
