Hi. I use bitlocker on a 500 gb partiton in my hard drive. Windows 7 is also installed in the same drive. before it was all fine but since this morning i hvnt been able to start windows(it hangs at the welcome screen). I switched on the computer then I enter the numerical bitlocker password ....then it hangs at the welcome screen. I tried accessing the Bitlocker encrypted drive from other operating systems....the drive is shown as locked. when i tried to open it, it prompts for the password. when I enter the password the computer freezes. Plis help me out. I have important datas in that drive.

Hi, I would suggest you to follow the methods below. Method 1: Test the issue in Safe mode http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode Method 2: Perform a clean boot If the error doesnt appear in Safe mode, then a non-Microsoft program might be the cause of the issue. A clean boot helps in eliminating software conflicts. Visit the link below to know how to perform a clean boot to get rid of the conflicting program.
