Currently, my boot sequence shows both SSD drives passing examination on boot. Then I get a black screen with a non blinking cursor in the upper left corner. The drive light shows no activity at that point. Waiting does nothing. If I attempt to boot from a thumb drive I can see the boot sequence on the screen, and then the black screen. It is almost as if the graphics loading fails.
Any insight, questions, solutions would be great.
If you have an NVIDIA card, then you driver is your issue. You are going to need to boot to a USB and then fix your install from there.
