Computer keeps booting with a black screen and flashing cursor.

It gets past bios but beyond that nadda. And on the slim chance i get safe mode to boot up. All i get is a black screen on safemode and a normal mouse pointer. I think my operating system is dead. Because when i used my windows vista cd to check for repairs it lists everything on the HDD as normal. As in i can see all my game folders. Is the solution to repair windows 7 using the cd? because i dont have a CD to boot it. since i left it with my friends when i moved over here lol. Im thinking about using killdisk and reinstalling vista untill i can buy a new copy of windows 7 64 bit

Try opening the task manager via ctrl+shift+esc. if it opens, go to run and type "explorer"

Use your vista disk and open up a command prompt, you can type fixmbr and fixboot to try and get it booting up, just google for how to use a windows disk to write a new MBR or to fix boot problems, there are plenty of good guides and I'm on my phone so I can't link you anything easily.JohnF111
