Saved up enough to buy a second-hand Surface Pro 5 to replace my Pro 3.
Nervous as it was £90, which is a massive amount for me, but if it works then yay. Granted, running Win8.1 on it was actually an okay experience, but once the replacement arrives, I'll be using it as a dedicated Linux machine (Zorin, probably) so I can get used to that.
Hate spending money, though... grew up poor and that's never left me.
So got those working, but when trying to install the linux surface kernel, it reboots to that same error.
It only boots if I turn off secure boot.
Think I'll just go back to Windows 8.1 and just deal with it not being too secure... or do I take it to Windows 10 and strip out a lot of the OS so it works at a better pace?
