I'm running a Lenovo Y500 Ideapad with Windows 8. I've had it for just over a year now, with no problems really whatsoever. Until now. I was playing Fallout: New Vegas, and my computer crashed and I had to turn it off using the power button. Once that happened, it got stuck into a "Preparing to Repair" loop. However, somehow, it eventually got to the troubleshoot menu. I tried to refresh it, but it said it didn't have access to the drive. I'd (obviously) rather not restore my pc to factory settings (and I'm not even sure if it would let me). I tried the other options in troubleshoot, but the System Restore, System Image Recovery, and Automatic Repair didn't work.
I do have access to the Command Prompt and UEFI Firmware Settings. I've done some googling, but I don't exactly know what I should do with either of these at this point, and I'm kind of nervous about making the situation worse by just trying stuff that worked in similar situations that I don't fully understand.
Any help would be greatly appreciated. Thanks.
