I recently needed a cheap 2 in 1 laptop, both for having a smaller lightweight astrophotography laptop, and for general usage. I chose the iOTA 360, currently on Amazon for less than 200£.

It was a bet, since looking around I couldn't find anyone claiming a successful GNU/Linux installation on it, but with some work I managed to get pretty much everything working.

The following guide should help you installing any recent version of Ubuntu on the iOTA 360.

A lot of these instructions/tools (including EFI 32bit bootloader, and Screen Rotator) can apply to other 2in1 laptops as well
