28. How to Perform a Startup Repair in Windows 7

  1. Boot from the windows 7 dvd 

The Startup Repair tool in Windows 7 replaces important operating system files that might be damaged or missing. Startup Repair is an easy diagnostic and repair tool to use when Windows 7 fails to start properly.
To begin the Windows 7 Startup Repair process, you will need to boot from the Windows 7 DVD.

1. Watch for a Press any key to boot from CD or DVD...

2. Press a key to force the computer to boot from the Windows 7 DVD. If you do not press a key, your PC will try to boot to the operating system that's currently installed on your hard drive. If this happens, just restart your computer and try to boot to the Windows 7 DVD again.
Note: Not using Windows 7? Every modern Windows operating system has a similar operating system file repair process

2. Wait for windows 7 to load files

No user intervention is required here. Just wait for the Windows 7 setup process to load files in preparation for whatever task you might want to complete. In our case it's a Startup Repair but there are a lot of tasks that could be completed with the Windows 7 DVD.
Note: No changes are being made to your computer during this step. Windows 7 is only temporarily "loading files."

3. Choose windows 7 setup language and other settings

Choose the Language to install, Time and currency format, and Keyboard or input method that you'd like to use in Windows 7.
Click Next

4. Click on the repair your computer link

Click on the Repair your computer link on the bottom-left of the Install Windows window.
This link will begin the Windows 7 System Recovery Options which contains several useful diagnostic and repair tools, one of which is Startup Repair.
Note: Do not click on Install now. If you already have Windows 7 installed, this option is used to perform a Clean Install of Windows 7 or a Parallel Install of Windows 7.

5. Wait for System Recovery Options to Locate Windows 7 on Your Computer

System Recovery Options, the set of tools that contains Startup Repair, will now search your hard drive(s) for any Windows 7 installations.
You don't need to do anything here but wait. This Windows installation search shouldn't take more than a few minutes at most.

6. Choose Your Windows 7 Installation

Choose the Windows 7 installation that you'd like to perform the Startup Repair on.
Click the Next button.
Note: Don't worry if the drive letter in the Location column does not match the drive letter that you know Windows 7 is installed on in your PC. Drive letters are somewhat dynamic, especially when using diagnostic tools like System Recovery Options.
For example, as you can see above, my Windows 7 installation is listed as being on drive D: when I know that it's actually the C: drive when Windows 7 is running.

7. Choose the Startup Repair Recovery Tool

Click on the Startup Repair link from list of recovery tools in System Recovery Options.
As you can see, several other diagnostic and recovery tools are available in the Windows 7 System Recovery Options including System Restore, System Image Recovery, Windows Memory Diagnostic, and Command Prompt.
In this guide, however, we're only repairing operating system files using the Startup Repair tool.

8. Wait While Startup Repair Searches for Problems with Windows 7 Files

The Startup Repair tool will now search for problems with important Windows 7 files.
If Startup Repair finds a problem with an important operating system file, the tool may suggest a solution of some kind that you have to confirm or may solve the problem automatically.
Whatever happens, follow the prompts as necessary and accept any changes suggested by Startup Repair

9. Wait While Startup Repair Attempts to Repair Windows 7 Files

Startup Repair will now attempt to repair whatever problems it found with Windows 7 files. No user intervention is required during this step.
Important: Your computer may or may not restart several times during this repair process. Do not boot from the Windows 7 DVD on any restart. If you do, you'll need to restart immediately so the Startup Repair process can continue normally.
Note: If Startup Repair did not find any problem with Windows 7, you won't see this step.

10. Click Finish to Restart to Windows 7

Click the Finish button once you see the Restart your computer to complete the repairs window to restart your PC and start Windows 7 normally.
Important: It's possible that Startup Repair didn't fix whatever problem you were having. If the Startup Repair tool determines this itself, it may automatically run again after your computer restarts. If it does not automatically run but you're still seeing problems with Windows 7, repeat these steps to run Startup Repair again manually.
If it becomes apparent that Startup Repair is not going to solve your Windows 7 problem, you do have some additional recovery options including a System Restore or a System Image Recovery, assuming you have previously backed up your entire computer.
You could also try a Parallel Install of Windows 7 or a Clean Install of Windows 7.
However, if you've tried a Startup Repair of Windows 7 as part of another troubleshooting guide, you're probably best served by continuing with whatever specific advice that guide is giving as your next step.
