I wanted to install elementary OS Loki in dual boot with my win10. For information, I have a old motherboard mode with legacy bios, I hope is not a problem to install elementary OS Loki.
I used Rufus and followed the tutorial (just in case I missed something), after selecting the USB stick, and before getting any install menu, I got this:
Remark: I tried to install Ubuntu to check my computer, I got the same error with > Ubuntu 16.X. But it's working with all Ubuntu (I tested the liveUSB mode only) <= 15.X, and finally it's working with elementary OS Freya (based on Ubuntu 14.X, if I remember well).
I didn't find out what change between these version yet :/ Any idea ?
