Hello, I have Teclast X80H FB5M dual boot. When I let windows update to windows 10, Android was damaged. I got the software from Teclast and flashed android and it is perfect but I coud not install windows. I think I used the wrong flash file and windows is gone but I flashed it again and it still the same. I can not boot the tablet from usb. There is only UEFI boot option only in the bios. Windows Boot Manager option does not appear and the bios does not read any external usb drive. I am thinking that wiindows partitions are gone an I need to do it manually but not sure.
Please help.
