How to Run a Startup Repair in Windows 7

Information

Startup Repair is a Windows 7 system recovery tool that can fix certain problems, such as missing or damaged system files (ex: MBR boot file), that might prevent Windows from starting correctly. This will show you how to run Startup Repair to allow it to scan your Windows 7 computer for a startup problem and try to fix it so your computer can start correctly.

 

   Note

Startup Repair is located on the System Recovery Options menu, which is on the Windows 7 installation disc. If your computer manufacturer (OEM) has preinstalled recovery options, Startup Repair might also be installed on your hard disk. If your computer does not include Startup Repair, your computer manufacturer (OEM) might have customized or replaced the tool. Check the information that came with your computer or go to the manufacturer's website.

 

   Warning

Startup Repair cannot fix hardware failures, such as a failing hard disk or incompatible memory, nor does it protect against virus attacks. Startup Repair is not designed to fix Windows installation problems. Startup Repair is not a backup tool, so it cannot help you recover personal files, such as photos or documents. To help protect your computer, back up your system and files regularly.

Here's How:
NOTE: Sometimes it may take running a startup repair a few (3) times before it fully fixes the startup issue.

1. Boot to the System Recovery Options screen.

2. Select the Startup Repair option. (See screenshot below)

3. Startup Repair will now scan your computer to attempt to find and fix any startup problems. (See screenshot below)
NOTE: Startup Repair might prompt you to make choices as it tries to fix the problem, and if necessary, it might restart your computer as it makes repairs. If repairs are not successful, you'll see a summary of the problem and links to contact information for support. Your computer manufacturer might include additional assistance information.

4. If problems cannot be found, then click on Next. (See screenshot below)
NOTE: You can click on the View diagnostic and repair details link to see a detailed summary of what Startup Repair has done.

A) Click on the Restart button to return to the Windows 7 logon screen. (See screenshot below step 2)
