From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do I add UEFI entries to boot any USB device? (feddit.de)

My stupid Lenovo "Thinkpad" UEFI doesnt have a real F12 devices menu.

It just shows registered UEFI targets that can be booted.

This is pretty catastrophic, somehow I got Fedora and Windows installed, but thats it. If something breaks, I am in trouble. I cant do a memtest86 even though I think my RAM is faulty.

So in Linux, is there a way to add an UEFI entry to boot just any USB stick? Or to boot a specific one, like with Ventoy on it?

Thanks!

Huh? Every ThinkPad I've had let's me boot to a USB drive. Check your bios settings something is off, unless it's through a company and they have it specifically disabled.

Not that one. Not from a company too. Maybe only using legacy only will solve this.

What model?

I'm not seeing anything that would be preventing this from showing up in the BIOS, is the USB drive formatted GPT? Does it recognize on any other computers? It may just be that it's not discovering the EFI file. Also check Startup > Boot > Excluded from Boot Priority Order, but this shouldn't matter for the F12 menu.

Some random thing fixed this. Maybe me nearly resetting my BIOS and then quitting? Or Windows attempting some "disk repair" again? Its showing devices now, since like half a year, its completely weird
