I have a really weird problem. I have a Thinkpad T495 with stupid proprietary Bios. In there, unlike for example Acer Bios, I have no option to add EFI keys or in general boot targets at all.
Currently I have setup Fedora and Windows boot manager, but I cant boot from USB! I checked my live USBs a lot, Tails, Ventoy, Kinoite, KDE Neon,… they dont work, dont show up in the F12 options or in Grub.
Do you know how I could fix this? It really sucks. Maybe I can use efibootmgr to create some generalistic USB boot target?
I have enabled legacy boot, disabled the “recommended Windows 8 settings” and all.
