A friend brought me his Nextbook 10.1" Quad-Core 2-in-1 tablet (EFMW101T) recently. I work in PC repair so he thought I could help him.
Problem: He upgraded the tablet to Windows 10 after creating recovery media on a USB drive. Something happened when 10 was finished installing, so he tried to roll it back to the previous version. He wasn't clear on what happened during the process, but now it's in a continual loop.
The tablet starts, and then (if the USB drive with the recovery image isn't inserted) ask for the recovery USB. It spins for a minute or two, and then says, "Restoring your previous version of Windows." It'll continue for about five to ten minutes, reboot itself, and then start the process all over again. I let this process go on for over 24 hours, and still nothing.
I tried holding down the power and volume button. It says to press the Windows key, but that doesn't work. Holding the Windows + I, and FN + F2 key does nothing.
Is there a way to get into the BIOS to get it boot from USB? If not, can this thing be reloaded somehow with a fresh install of Windows 8.1?
