Why does Startup Repair not work in Windows 10/8/7?

When the hard drive file system, boot partition or BCD setting is damaged due to disk write errors, power outages or virus attacks, this problem will be triggered in Windows 10/8/7. Besides receiving the hint “Startup repair cannot repair this computer automatically”, there are chances that you will be stuck into Startup Repair loop in Windows 7/8/10.

What can I do if Windows Startup Repair doesn't work?

If the Windows 7/8/10 system Startup Repair does not work and cannot repair boot problems automatically, we can try the following solutions one by one. But you must have a Windows 7 installation disc at first.

▌Solution 1. Run CHKDSK.exe on the boot partition

To run CHKDSK.exe tool when Windows fails to boot, you need to do:

1. Insert your Windows 7 installation disc into the CD tray, and boot Windows from it.

2. Press any key when “Press any key to boot from CD or DVD” appears.

3. Click “Repair your computer” and wait for Startup Repair to scan your computer, then select your OS from the given list.

5. Once the command prompt window is launched, enter the command “chkdsk /f /r c:” and press “Enter” to check your boot partition for errors. (c is the letter of your Windows installation drive)

1. Restart your Windows 7 computer. Wait for the BIOS to complete the POST.

2. Quickly begin tapping ESC, F2,F8 or F12 constantly until you see the boot options.

3. Choose “Disable automatic restart on system failure”.

4. Press Enter and wait for your PC to boot.

Solution 3. Run the sfc /scannow command

Besides running “chkdsk /f /r c:” command, you can also run the sfc command (System File Checker) to scan system files and repair corrupted files in Command Prompt window. When you open Command Prompt window like you do in the first solution, run the following command.

sfc /scannow /offbootdir=d:\ /offwindir=d:\windows


Finally, when the process is completed, you can restart your computer.
