Method 1. Rebuild corrupted MBR

If you see an error message like "system missing," "operating system not found," or encounter a black screen with a blinking cursor when booting up, the issue may be due to a damaged Master Boot Record (MBR). To repair Windows 10 from another PC, you can use AOMEI Partition Assistant. It allows you to create a bootable USB drive on a working computer, then boot the PC with the damaged MBR from that USB, and repair the corrupted MBR without losing any data.

Step 1. Connect a blank USB drive to another working Windows computer that can boot up normally. Download, install and launch the AOMEI Partition Assistant on that PC as well.

Step 2. Click "Tools" > "Make Bootable Media" on the upper interface, a window pops up, click "Next".

Step 3. In the next window, choose "USB boot device", then press "Proceed".

Step 4. Click "Finish" when the operation is done.

Step 5. Boot your Windows from the WinPE bootable USB you created. It contains the preinstalled AOMEI Partition Assistant software. Once log in, the software will run automatically.

Step 6. Right-click the system disk and choose “Rebuild MBR”.

Step 7. Choose the proper MBR type for your current OS.

Step 8. Click on “Apply” and “Proceed” to commit the pending operation.

After it is done, the damaged MBR will be rebuilt. Besides, you can also use this software to activate the Windows partition. Right-click the boot partition, and select "Advanced">" Set Active Partition".

Method 2. Repair corrupted or missing BCD files

There is a possibility that your Windows 10 may fail to boot due to corrupted or missing BCD files, boot sector damage, failed updates, or virus attacks.

The BCD (Boot Configuration Data) file contains essential information required for Windows to boot. It is located in the EFI system partition for EFI-based systems or the system reserved partition for MBR-based systems. Fortunately, the "Boot Repair" tool in AOMEI Partition Assistant offers an easy and effective solution for repairing Windows 10 from another PC, helping to smoothly restore your system's normal boot function.

Step 1. Install and launch AOMEI Partition Assistant on a working PC, click "Recovr"-"Boot Repair" and then click the "create a bootable disk" option to create a WinPE "Boot Repair" disk.

Step 2. Boot the PC that cannot boot into WinPE. It will automatically load the Boot Repair tool and start the boot entries scan process. All boot entries will be displayed.

Step 3. Select the repairable boot entries you want to repair and click the "Repair" button to start the repair.

Step 4. Once the repair is repaired successfully, you can remove the bootable disk and boot the PC from the original system drive.
