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!

WTF, the BIOS doesn't let you select the boot-order? Which Thinkpad is this?

Weird, suddenly, after like 20 tries, I can boot any media? Wtf?

Yes I could select the boot order but only for the UEFI entries (Fedora, Linux firmware updater, Windows Boot manager)

Not for plugged in devices. I never saw the name of my NVME for example, now suddenly its there?

I hate this proprietary garbage Bios so much, I cant wait to get a Clevo NV41MZ and flash dasharo on that, then try Heads.

Never heard of the Clevo before, thanks

Novacustom and 3mdeb do all the work. So if you want to support them, get a machine from them!

Did you enable CSM? By default you should never see a device to boot from and should only see valid UEFI targets.

[–] [email protected] 2 points 1 year ago (1 children)

What is CSM?

[–] [email protected] 3 points 1 year ago (1 children)

Compatibility Support Module. It'll allow you to boot non-UEFI things. I often disable that to enable secure boot.

Thanks, that can be it!
