blank screen with blinking cursor at boot to win10

Upgraded to windows 10.

Everything worked great for a few weeks. Recently turned off the computer and can't boot to windows anymore. The computer gets stuck on blank screen with blinking cursor. Will not show any win 10 screens.

Any suggestions?

Thanks,

 

Black screen with blinking cursor

I run Windows 10 and have a black screen with a blinking cursor in the upper left corner. I can hit Control, Alt, Delete, and it reboots momentarily, show the Dell logo and F2 Setup anf F12 Boot Options in the lower right corner. Regardless of what key
I hit, it goes right back to the Black screen w/ cursor. I can't seem to do anything. Any suggestions?
