W10 external drive display problems
So I'm trying to get W10 running on an external J500 T-bolt drive, I'm using Winclone.
My internal bootcamp runs perfectly, when I try to boot into the external drive partition I can reach the login screen just fine, but when I get to the desktop the viewable menus and mouse cursor start flickering the mouse specifically seems to 'flicker' between the actual cursor and a loading icon. I can not use the mouse(I can move it around) and keyboard commands seem to only partially work. I can CTLR+ALT+delete into the task manager, log out, switch users, ect, but can not simply navigate to anywhere using say, the command key and arrow keys. Unfortunately I can't boot into safe mode by this method and I'm kind of dumfounded on what this could be. Possibly a display driver problem but it only happens on the external drive.
Curiously Disk Utility reports a 5GB difference between the used space between my external and internal drives (they're supposed to be mirror images)
not sure what's going on with that.
Specs;
iMac late 15 6700K/ 1TB SSD

I'm using a Transcend J500 512GB SSD T-Bolt drive, which I've seen other people successfully use.
Anyone have any problems?
