And tell more. Unless a clue is revealed such as "the BIOS mode was changed from AHCI to LOLC" I think you are looking at a factory recovery (hope you had nothing on that laptop!)
Toshiba Satellite Laptop Model L775-S7108; Windows 7. I attempted to troubleshoot "Loading Windows" at Toshiba's website but no luck. I tried to load in safe mode by pressing f8 as instructed and it just continues to the "startup repair is checking your system for problems" screen. From this point, it just runs and runs. Can someone please assist?
