I have a Windows 8 laptop and it recently said Windows has encountered an Error and needs to restart, Bad-System-Config-Error, I waited for it to restart, it attempted to repair itself and failed and now I cannot get to my computer home screen! Heeeeelp! it just keeps restarting and attempting to repair, and Failing!
Sounds like, what Brett is saying,DaneMcAfee.
So i would follow his good advice.
Mind you did you just buy the laptop, I mean if it was pre installed then it must be fairly new. Or did you install windows 8 on it yourself Dane ?
If you just bought it and this is happening take it back.
Most places have a 90day window for these things to happen.
Don't monkey around with it on your own, especially if you don't know what you're doing.
