I had to screw around with the UEFI boot option on my Toshiba laptop to test a Ubuntu OS, and it borked my Windows installation.
Took me an hour to figure out how to get it back.
You probably have a similar issue - you have to screw with UEFI stuff, and the machine won't like it.
It is actually a cheap little Windows 10 Chinese touchscreen Walmart / SamsClub special, called a Nextbook. They sold a ton of them and there was an active community of people trying to get the most out of them. The issue was a lack of certain essential drivers. So no one that I know of was ever able to get full functionality. I wasted quite a bit of time myself, but it always turned into a dead end. It was things like no wifi, no sound, no touch screen and touchpad drivers and stability problems. It has limited resources so I am sure that Linux would make more efficient use of the thing if it were not for the lack of drivers.
