Startup Repair Cannot Repair This Computer Automatically

Please help me, any advice will be grateful, Thanks.

Why is Startup Repair not working?

Startup Repair is a Windows native tool to help fix certain system problems that might prevent Windows 7 from booting up successfully. For example, it can fix damaged or missing system files used to load the operating system. However, why does Startup Repair not work? The main reasons conclude "a problematic device attached to your computer", "damaged file system of your system disk", "bad sectors on the boot drive", "the corrupted MBR of the hard drive", etc. Next, we will show you how to fix this error.

5 Fixes for “Startup Repair cannot repair this computer automatically” error

The following content aims to tell you how to fix the Startup Repair not working issue in detail. You can try them one by one until the problem gets resolved.

Fix 1: Remove All External Devices

If you connected storage devices to your current computer, the computer might recognize the external hard drive like USB flash drive as the system boot partition, and Startup Repair tool check the USB drive instead of the actual boot partition on the disk. Thus, the “Startup Repair cannot repair this computer automatically” error occurred. So you can try to remove the device and restart the computer to check if this problem disappears. If it does not work, proceed to the next fix.

Fix 2: Repair Bad Sectors

1. Generally speaking, the bad sector could be the root cause for this Startup Repair offline error. Therefore, check and fix bad sectors with Command Prompt (chkdsk.exe) will take you out of the trouble, here is how chkdsk works:

2. Boot your computer with Windows installation disc.

3. Choose Repair your computer -> pick your system drive (usually C:\), and click Next.

4. Select Command Prompt in System Recovery Options window, then input the command and execute: chkdsk c: /f /r (C: usually the Windows installation drive).

Then, check if the “Startup repair cannot repair this computer automatically” error solved. However, you might encounter chkdsk is not available for raw drives, the comprehensive disk manager - AOMEI Partition Assistant Standard, and the Check Partition will save your life.

Check The C Partition

Fix 3: Run Bootrec

A missing boot manager can also lead to the “Startup Repair not working” problem. If so, you can run bootrec commands to fix this issue.

1. Open Command Prompt following the instructions mentioned above.

2. Type “Bootrec /RebuildBcd”, and then press “ENTER”.

If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. Then you can add the entry to the BCD store by the command-bcdedit /copy {current} /d "DebugEntry", (BCDEdit copies the Microsoft Windows boot entry that was last used to boot Windows, identified as {current}, and creates a new boot entry. The /d description option specifies DebugEntry as the name of the new boot entry). A confirmation message appears that indicates the entry was added successfully.

If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and re-create it. To do this, type the following commands in the order and press ENTER after each command.

  • Bcdedit /export C:\BCD_Backup

  • ren c:\boot\bcd bcd.old

  • Bootrec /rebuildbcd

Fix 4: Rebuild MBR

If the MBR is corrupted, your computer could not read the MBR to start Windows Boot Manager in the PreBoot process according to Microsoft. So, you might meet the “Startup Repair cannot repair this computer automatically” error. To repair damaged MBR, the powerful AOMEI Partition Assistant Standard offers the easiest method, just refer to these steps:

1. Download this freeware, and create WinPE bootable media on a working computer. The bootable media will contain the standalone AOMEI Partition Assistant Standard version.

4. Choose MBR type for your Windows 7/8/10 operating system, and click OK.

5. Click Apply at the top left corner. Then, press Proceed to confirm this operation.

2. After enter OS, and then go Start ->All Programs ->Accessories ->System Tools ->System Restore, then use the system restore point to restore your computer back to normal.
