Help with Dual Boot with Ubuntu

Hi all,
Well I sent this question to the Chuwi help email address,


I have bought one of your Larkbox with windows 10 installed on the eMMc, but I have also put a M.2 SSD in the slot and want to put Ubuntu on this for a dual boot system, I have heard some horror stories about bricking the system with changes in the BIOS, so do you have instructions for this, or any pointers I need to know on having and setting up a dual boot system…

Much appreciated


And this was the answer I got back today……what the hell…???. How on earth does this help me…….:rage::rage::rage:
