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.
Can you boot to the BIOS?
I can get to a grub command line.
