Below is the screenshot of the error I get while Windows 7 loads. Any idea what it is?

C:\Windows\System32\winrnr.dll is either not designed to run on Windows or it contains an error.

Couple of things to try:

Open an elevated command prompt (right click on the icon for cmd.exe and choose "Run as administrator.") and run: SFC /scannow

If that doesn't fix the problem (do a restart after running SFC to test) open an elevated command prompt again and run: Regsvr32 winrnr.dll

Finally, if none of the above works try an in place upgrade. (n.b. this instructions are for Vista and I have never performed an in place upgrade for Windows 7 but I assume it is very close to being the same)

In-place Upgrade

  1. Start the computer by using the current Operating System.
  2. Insert the Windows Vista DVD in the computer's DVD drive.
  3. Use one of the following procedures, as appropriate:

    • If Windows automatically detects the DVD, the Install now screen appears. Click Install now.
    • If Windows does not automatically detect the DVD, follow these steps:
      a. Click Start, click Run, type Drive:\setup.exe, and then click OK. Note: Drive is the drive letter of the computer's DVD drive.
      b. Click Install now.
  4. When you reach the "Which type of installation do you want?" screen, click Upgrade to upgrade the current operating system to Windows Vista.
