I can not access the bios from startup and always have to go through windows, which is extremely inconvinient as I often switch between OS’s. It seems that the keyboard isn’t initialized when the Ubook is starting up. Any tips?
Have you tried a USB connected keyboard?
Works every time, thanks for the idea!
However, this solution kinda sucks as I cannot switch OS’s on the go this way 
If all you want to do is pick the OS on boot, why don’t you install the GRUB Bootloader?
I experienced grub as an extremely inconvenient tool to work with. Mainly because of the way it integrates with Windows (which I definitely need to keep). But I might give it another try tho
