Windows 10 | Use a device button missing | Rescue disk

[system]

So previously I had problems with installing the avast rescue disk, but I sorted that out, but now, when I use the advanced start-up menu, the ‘Use a device’ button is not there.

I’ve looked online, and I can’t find a fix that works.

You already have a topic to deal with your probably infected computer. Please stick with that topic
New topics only confuse and convolute the attempt to help.

Have you tried enabling the USB device as a boot device in the BIOS?

Also, is this a Win10 machine with UEFI “Secure Startup” enabled?

Yes. But that isn’t do to with this. This is an error, not a infection.

It is the 3rd boot device (idk what that means) by default.
It is a win10
And yes.
Also, apologies if I am late replying, I had a family event to go to.
