For those who want dual os on the teclast x2 pro, got it working with the android x86 cm13 version.
also tried out the normal android x86 rc6, which is a bit more convenient to use because of the resolution (icons are bigger ...) but still wifi isnt working
just put the android x86 cm13 iso with win2disc on sd install on another partition without install grub to win partition! then boot windows and install grub2win, change boot priority to win2grub bootloader. now you be able to switch between each installed os.
the only problem seems to be switching the os without the keyboard,because the touchscreen doesnt recodnize any type.
i found some "switch os" files for other teclast dual os tablet, but they arnt working.
if anybody find out a way to get this done pls free to let me now, thx
