This little thingy did a trick for me! Just check enable when the program starts. Please use it at your own risk as I obtained it from another forum (X16), and I don’t know does it interfere with previous BIOS tweaking on Tbook 16 Power (mine is M5F8). Cheers, Goran
Thank you so much Goran!!!!!! Finally I have the screen selection again!!
Ok, finally I fixed reinstalling all manufacturer firmware; windows 10 installing following Teclast manual is diferent to microsoft’s media creator, and it seems to create all needed partitions and boot files.
