I have used a usb hub, keyboard and a usb stick with Android X86. It runs pretty slow on my tablet, but it works.
You can enter the bios when you type in “exit” in the EFI Shell. For me it starts up the Bios then.
I’ve made a pretty good step. I’ve made a Windows Boot Stick which wasn’t working. But I’ve installed Android x86 as a boot image and now I can start the tablet from Android at least. Very slow, but it works. Now I need a way to recover Windows from Android.. But I think that should be doable.
If someone has an answer for this, I would like to give in a question that belongs to it: Is it possible to install Android only without having Windows installed? My X98 Air 3g just broke my Windows Only Installation and because I’ve had much issues with it I would like to install Android only too. (Just playing around until I sell it to buy a new Cherry Trail Tablet.)
