I have two USB drives, one is 8G Kingstone, and the other is 32G not Kingstone.
Kingstone USB key was stuck at Green Bar( ‘Loading Basic Drivers’ was shown with ‘esc’ key ).
So, I made installation media again with 32G USB key(the other one) with exactly same method.(BTW, which was Rufus with ISO. not DD).
And installer booted OK.
I think that problem can be related with USB drivers.
I don’t think it’s USB drivers, they’re in the kernel. To me it looks like writing to the 8 GB didn’t go right. If the stick was used before as an install medium, it could have remains from a hybrid filesystem.
