Windows Vista Windows Vista won't boot

My HP laptop with Windows Vista was working perfectly fine until one day it suddenly wont boot after I turned it on. I didnt remember installing any programs after this occured. I just removed the battery to turn it off and tried to turn it on. Message appeared that an error occured and there was an option to repair it. I chose repair but after loading windows file with the command propmt, it went blank. I waited for like 15 mins but nothing happened. Tried to remove again battery and truned it on. I thought of doing System Restore with command prompt in Safe Mode but still the same - it will load Windows files then will trun blank for minutes. I dont know how to fix this. Please help. Thanks a lot!!!

 

First of all, try a Vista Startup Repair, which can cure a lot of problems http://www.vistax64.com/tutorials/91467-startup-repair.html

 

A slow but mostly working way is to burn a CD with GParted http://gparted.sourceforge.net/
and use it to boot Windows Vista (Do not boot GParted though)
