Hello, I'm having an issue with my Dell Precision M4600. I'm ridiculously new to this whole thing. I only ever work on computers. Not in them. But I started it up one day and it wouldn't go to the login screen. Instead it went to a system repair thing. I messed with that the best I could, but to no avail. I tried reinstalling Windows, but it only says "No signed drivers could be found." I've been told by a barely semi-reliable source that I need a new internal HDD. But I'm unable to acquire one at this moment. The thing is a little over a year old. But it's been like this since the past July and I'm starting to get really frustrated. Is there anyway you can talk me through what I'm doing, and possibly help me out here?? I apologize for the lack of detail. But as I said I have no clue what I'm doing. I can post pictures if that helps?? Thank you.
