I have a big problem: I have tried to install Windows 10 on my ThinkPad T420 from an USB-Stick, but I can't boot from it. The T420 has no OS and no DVD player. I tried an installation with a windows stick and an ubuntu stick, nothing works. Also I have set the BIOS options Legacy Mode to "Both". Unfortunately I can't disable the secure boot because there is no secure boot option!? :/
There are any ideas?
