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.

Solved :USB Boot not showing in Thinkpad e14 (programming.dev)

As the title says, my bootable usb is not showing up in the boot menu for my ThinkPad e14 AMD ryzen 5 7530u , gen 5 I think. I have disabled secure boot in the uefi and disabled fast startup in windows. Am I missing anything ? Note: this is my first time using a uefi bios so I don't know if there are any other kinks to mess with .

Edit : I contacted lenovo support for the above issue but even they couldn't find the answer so I guess won't be using linux for this laptop. But since it's for uni I guess it's fine. I will just use WSL

Edit 2: Reinstalled the bios , the usb boots now . Finally slapped opensuse on it and now running it

I suggest a few more things:

Try a different brand usb. Different motherboards sometimes don't support some usb brands. In fact, a Lenovo server I rebuilt refused to boot off certain usbs.

Some motherboards don't initialise boot off some usb ports. Sometimes the additional ports are on another controller and initialise too slow.

Just try a straight working Ubuntu live boot usb to remove any ventoy from equation. Ubuntu has real signed uefi (and no shim) granted by Microsoft. I think that's how it works, uefi is a mess.

Try to start isolating all the different factors, and there could be more. It doesn't necessarily mean anything definitive if it works on another machine.

Tried right now with a SanDisk with just Ubuntu using Rufus but that also does not show up

And you probably confirmed that live boot worked too I assume.

In the actual bios, can you see a boot order and see uefi for Windows/whatever is on your internal disk? But not any other entries?

I can see the windows boot manager, the nvme sdd and pxe boot thats it

Other then legacy and uefi does it have a CSM compatibility support mode? An option to enable usb initialisation before bios? Eg wait for usb initialisation?

Some "boot faster" options kind of reorder boot initialisation to a point where it's not holding the system back.

Though I'm really running out of suggestions.. I can imagine you're pretty frustrated. I know my Dell laptop was a pain to get the right settings to get usb to boot and the stupid 100db beep to silent on boot interruption.

No options for csm , no usb initialisation as well
