I've been trying all night to get Ubuntu mate running on my PC but have kept running into problems with the installation. I've made a boot disk, and plan on using it to get into a live "try ubuntu without installing" session and then from there install it onto a 64 gb flash drive. After many, many error codes and scouring forum after forum I finally got ubuntu live to boot, but I had to switch my boot option from "Uefi+Legacy" to "uefi only" for it to work. After that my main windows drive wouldn't show up in the boot drive selection page of my bios, even if I switched back to legacy+uefi. I finally got all of that sorted out and my windows drive booting again but get the same errors when trying to boot ubuntu. Am I going to be forced to reinstall windows in the uefi only mode or is there a workaround that will allow me to boot into Ubuntu without changing my uefi settings? Any help would be greatly appreciated.
