Okay I tried to boot my laptop with Win7 and it goes to a menu with two options.
1- Launch Startup Repair
2-Start windows normally

When I try the second option it gets stuck on the windows is starting up screen and a blue screen error flashes for a fraction of a second. When I try the first option I get stuck on a grey screen after it says "windows is loading files". I tried every other start up option in advanced boot menu, but they all cut back to the first two options. What should I do?
