I got a Thinkpad X13 Yoga (Gen. 1) where I got no access to BIOS settings. I got it from a former job and the settings are password protected.
The BIOS is updated as the box has been running Windows 10 until recently and I have updated regularly using the Lenovo update tool.
I successfully installed Linux Mint, 6 weeks ago, using a live USB stick and I can also boot with Clonezilla, Macrium backup and Windows boot sticks.
EOS boot media will not load though. As secure boot is probably turned on I guess there is no way I can get EndeavourOS up and running?
