Hi Singular1ty,
· What is the exact error message that you received?
I would suggest you to try the steps mentioned below and check if it helps to resolve the issue.
- Change the boot order in the CMOS setup so that Hard Disk is first on the list. Make sure you select the hard drive on which Windows 7 is installed.
Note: For information about how to do this, see the documentation that was included with your computer, or contact your computer manufacturer.
- Restart your computer and see whether the problem is resolved.
- If the issue still persists run the Bootrec.exe tool in the Windows Recovery Environment to repair startup issues in Windows.
