Fix BitLocker Access is Denied Error

Problem :

I am trying to enable BitLocker on a Windows 7 Enterprise C:\ drive and the laptop that I am doing this on does support TPM. The problem is, when I go to the control panel>Bitlocker Drive Encryption> and tell it to turn on bitlocker for the C:\ drive; it gets past the TPM initialization and stops at "Please wait while Bitlocker initializes the drive" and below that says "Access is denied".


Solution :

These files were malformed:

1) Bootres.dll

2) Winload.exe

3) Winload.exe.mui

4) Bootmgr
