I own a Toshiba satellite C675 w/Windows 7 updated to Windows 10:
Started it up and black screen w/red print said "WARNING" Toshiba Recovery Wizard. It said it would either recover system to "out of the box" OS and erasing all data or I could select recovery using my data. It had a yes or no at the bottom of the screen. I selected "No" thinking it would jump out of recovery mode and load up like normal....... Well it's been thinking ever since.
