10 Easy Fixes to Boot into a Cloned Windows 11 Partition After Green Screen of Death

Ah, classic move! You've cloned your system, but now you're stuck on how to reboot into that shiny new partition. Let’s try some quick fixes to make sure you’re good to go:

1. Enter BIOS/UEFI Setup

Restart your PC and rapidly press the BIOS/UEFI key (usually F2, Del, Esc, or F10).
Once in BIOS, check your boot order settings. Ensure the new disk or cloned partition is selected as the first boot option.

2. Use the Boot Menu

If your system has a boot menu (usually F12 or Esc during boot), press it and manually select the new partition (M:).

3. Fix Boot Configuration with Bootrec

If the new partition isn’t booting, we might need to fix the bootloader.
1. Boot from a Windows installation USB or recovery disk.
2. Choose Repair your computer > Troubleshoot > Advanced options > Command Prompt.
3. Type the following commands to repair the bootloader:
```
bash
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
```

4. Mark the Partition as Active

Sometimes the partition isn't marked as bootable. You can fix that with Diskpart:
1. Open Command Prompt as Administrator.
2. Type diskpart and press Enter.
3. List your disks with list disk and select the correct disk.
4. Select the cloned partition with select partition X (replace X with the correct number).
5. Type active to mark it as bootable.
6. Restart your PC.

5. Rebuild the BCD Store

If Bootrec doesn’t do the trick, manually rebuild the BCD (Boot Configuration Data):

Open Command Prompt as Administrator.

Type:

bash
bcdedit /export C:\bcdbackup

Then delete the current BCD:

bash
attrib C:\boot\bcd -h -r -s
del C:\boot\bcd

Rebuild it:

bash
bootrec /rebuildbcd

6. Check Boot Partition with Disk Management

Open Disk Management (Win + X > Disk Management).
Right-click the cloned partition (M:) and ensure it’s labeled as Active.

7. Use a Third-Party Boot Manager (e.g., EasyBCD)

Download a tool like EasyBCD to add the new partition to the bootloader:
- After installation, open EasyBCD, click Add New Entry, and choose the partition you cloned to.
- Click Add Entry, then restart.

8. Check the Partition for System Files

Make sure that the cloned partition (M:) has all the necessary boot files (like bootmgr and the Windows folder).
If not, you may need to clone it again, making sure all system files are included.

9. Try a System Repair

If the new partition still isn’t working, boot into Safe Mode (by pressing F8 or using Startup Repair).
From the Advanced Boot Options, select Safe Mode with Command Prompt and run a System Restore or Startup Repair.

10. Use AOMEI Backupper to Re-Clone

If all else fails, you can try re-cloning the partition with AOMEI Backupper, ensuring you clone all necessary boot-related files. Make sure the new partition is a proper system partition during the cloning process.

After trying these fixes, your system should boot into the cloned partition. If it doesn’t, let me know and we can dig deeper!
