I do own a tablet (Xoro PAD 9W4), which initially ran Windows 8.1. I upgraded to Windows 10, but due to some issues (mainly touchscreen issues), I want to reinstall Windows 8.1. For this reason, I made a bootable USB flash drive.
Although I managed to enter UEFI BIOS, there is no option in boot manager to boot from usb. In particular the displayed message is: System doesn't have any USB boot option. Is there anything I can do about it?
P.S. Unfortunately, there is no official support for the specific model.
