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!

    rEFInd can auto-detect bootable devices, and you can select them during startup. You need to install it to the efi partition as your boot manager.

    With a simple config edit and file copy operation, I put a memtest86 efi image on my boot partition, and it shows up as an option for every boot. It’s nice to know I won’t have to fumble around with USB drives if I need to test my RAM in the future.

      Thats awesome! But sounds pretty hacky… so I would remove grub and use refind instead?

      Fedora Kinoite is built for Grub afaik, with the deployments and all. Not wanting to destroy that really…
