Fix 2. Extend the System Partition to Fix Windows Automatic Repair Loop

Windows and some applications require enough space to work correctly. If the system drive on your computer is almost full, you may encounter problems like "Your PC ran into a problem" or Windows stuck at "Preparing Automatic Repair".

To make more free space for the system and applications, the professional partition tool - EaseUS Partition Master can extend the system partition from a bootable disk and rescue the computer from a blue screen of Automatic Repair error:

1. Create a Bootable Disk on Another Healthy PC

Step 1. To create a bootable disk of EaseUS Partition Master, you should prepare a storage media, like a USB drive, flash drive or a CD/DVD disc. Then, correctly connect the drive to your computer.

Step 2. Launch EaseUS Partition Master, and find the "Bootable Media" feature on the left. Click on it.

Step 3. You can choose the USB or CD/DVD when the drive is available. However, if you do not have a storage device at hand, you can also save the ISO file to a local drive, and later burn it to a storage media. Once made the option, click the "Create" button to begin.

  • Check the Warning message and click "Yes".

When the process finishes, you have successfully created an EaseUS Partition Master WinPE bootable disk. Now, you can manage your hard disks and partitions through the bootable drive whenever the computer fails to boot normally.

If you have RAID drives, load the RAID driver first by clicking Add Driver from the menu bar, which can help you add the driver of your device under WinPE environment, as some specific device cannot be recognized under WinPE environment without drivers installed, such as RAID or some specific hard disk.

2. Extend System Partition from Bootable Disk

Connect the bootable disk USB to your problematic computer and restart the PC. Press F2/F11/Del to enter BIOS. Set PC to boot from the bootable disk.

When the computer boots up from the EaseUS WinPE bootable disk, enter EaseUS Partition Master and extend the system drive with the steps below:

Option 1. Extend System C drive with unallocated space

  1. 1. Right-click on the System C: drive and select "Resize/Move".
  2. 2. Drag the system partition end into the unallocated space so to add it to the C: drive. And click "OK". 
  3. 3. Click "Execute Task" and "Apply" to execute the operations and extend the C drive.

Option 2. Extend System C drive without unallocated space

  1. 1. Right-click a big partition with enough free space on the system disk, select "Allocate Space".
  2. 2. Select the system drive at the Allocate Space From (*) To section, and drag the end of System C drive into the unallocated space. Click "OK" to confirm.
  3. 3. Click "Execute Task", it will list the pending operations, and click "Apply" to save the changes and extend the C drive.

0:00-0:26 Extend System Drive with Unallocated Space; 0:27-0:58 Extend System Drive without Unallocated Space.

3. Restart PC from Original OS Disk

After extending the system drive, you can now restart the PC from the original system disk:

Step 1. Restart the PC and press the F2/F11/Del key to enter BIOS.

Step 2. On the boot menu, switch and set the original system disk as the boot drive.

Step 3. Save the changes, exit BIOS, and restart the PC.

Wait for the computer to boot up. If you see the login window, congratulations and you've successfully solved this issue. If the problem still exists, move to the next fixes for help.

Another way to get out of the Windows Automatic Repair loop is to disable early launch anti-malware protection. You can do this from Command Prompt with the following steps:

Step 1. Restart the PC and click "Advanced options" on the Automatic Repair blue screen.

Step 2. Click "Troubleshoot" > "Advanced Options" > "Startup Settings".

Your computer will restart and then present you with a list of options.

Step 3. Choose "Disable early launch anti-malware protection".

Windows Startup Settings - Disable Early Launch Anti-Malware Protection

After this, restart your PC and check if you can boot into Windows.

Fix 4. Run System File Checker & CHKDSK Disk Utility

If the computer system files are damaged or missing, that's probably where the issue originates. Windows provides a built-in System File Checker and CHKDSK Disk Utility for users to check and repair missing or corrupted system files.

Warning
Running chkdsk can hopefully fix the system files issue, however, it can also result in total data loss. So, perform data recovery in advance, and then continue with the CMD method.

To use the tool, you need a Windows installation media connected to your computer and fix the blue screen error with the steps below:

Step 1. Reboot your PC from the Windows installation media.

Step 2. On the Windows Setup window, choose "Next".

Step 3. Choose "Repair your computer" > "Troubleshoot" > "Advanced options" > "Command Prompt".

Step 4. Type sfc /scannow and hit Enter.

Step 5. Type chkdsk /f /r /x C: and hit Enter.

Run CMD to fix automatic repair loop error

Step 6. Type exit to close Command Prompt and restart the computer.

Fix 5. Rebuild BCD to Fix Windows Automatic Repair Error

If the Master Boot Record (MBR) and Boot Configuration Data (BCD) are missing, corrupted, or not properly configured, Windows won't be able to start. If this is the case, enter Windows and manually repair the MBR and rebuild the BCD.

 When your computer fails to start, bootrec.exe can be used to fix the Master Boot Record (MBR), Boot Sector, Boot Configuration (BCD), and boot.ini.

Step 1. Connect the Windows installation media/disc to your PC.

Step 2. Start and boot your PC from Windows installation media or DVD.

Step 3. On the Windows Setup window, choose "Next" > "Repair your computer".

Step 4. Choose "Troubleshoot" > "Advanced Options" > "Command Prompt".

Step 5. When Command Prompt appears, enter the following lines in succession:

  • bootrec /fixboot
  • bootrec /scanos
  • bootrec /fixmbr
  • bootrec /rebuildbcd
  • exit

Afterward, restart the PC and check if your computer boots up normally. 

Fix 6. Restore Windows Registry

The Registry is a database that contains the configuration information of the operating system and most of the applications. When Registry corrupts, it may lead to serious problems like the Automatic Repair loop.

The good news is that the registry makes a backup of configuration data automatically. You can use the backup to restore the Windows registry to a working version.

Step 1. Choose "Advanced options" on the blue screen of the Automatic Repair error.

Step 2. Navigate to "Troubleshoot" > "Advanced Options" > "Command Prompt".

Step 3. Select the account and enter the password.

Step 4. Enter the following commands one by one and hit Enter each time:

  • C:
  • CD Windows\System32
  • CD config
  • DIR
  • CD regback
  • DIR
  • CD..
  • REN default default1
  • ren sam sam1
  • ren security security1
  • ren software software1
  • ren system to system1
  • CD regback
  • copy * c:\windows\system32\config

Step 5. Type exit and hit Enter.

In the "Choose an option" screen, choose "Turn off your PC" and then start your computer.

Fix 7. Perform System Restore to Fix Windows 10 Automatic Repair Stuck

If you have created a Windows restore point before the Automatic Repair loop occurs, you can perform a system restore to cope with the issue.

Note that performing system restore will overwrite your files on the system C drive, remember to get your data out of the computer first. You can revert to restore data in two reliable ways.

Here are the steps:

Step 1. On the Automatic Repair blue screen, choose "Advanced options".

Step 2. Navigate to "Troubleshoot" > "Advanced Options" > "System Restore".

Perform system restore

Step 3. Choose a restore point, click "Next" to restore your computer to a healthy state.

Step 4. Wait until the restore process finishes and then restart your computer.
