I have a lenovo laptop from late 2018 and I fail to install windows 7 using rufus and a bootable usb. It freezes after the first reboot.
Also, I can't install any version of windows 10 prior to 1709. Same thing, spinning dots keep spinning for ever after the first part of the installation (first reboot).
For some reason, I did succeed once installing windows 1703, but it never worked again after many other attempts.
Does anyone know if there is a way to bypass this ? I tried to roll back to previous bios versions but with no success.
