Shutdown tablet. Try push Power Button and vol+ together for 2 seconds.
I try from android and windows (+-)power with no luck.
any other suggestion?
Is this switcher is build in the boot or in bios?
How to get it back?
I found the way.
Need to log to android then reboot to windows and after 3-5 sec of booting by pressing – + I did get the option screen and enable a check mark.
I missed to write the words “while booting”. Thanks.
