How to Fix Acronis Clone Not Booting with 3 Ways

If you are experiencing issues with an Acronis clone not booting, there are several ways you can take to troubleshoot and resolve the problem. Here's a step-by-step guide:

1. Check Connection and Configuration

Ensure that the cloned drive is properly connected to your system. Verify that the boot order in the BIOS/UEFI settings is configured correctly, with the cloned drive set as the first boot device.

Step 1. Ensure your computer is powered on, and then restart it.

Step 2. During the startup process, you need to access the BIOS or UEFI settings. The key to enter these settings varies (common keys include F2, Del, Esc, F10, or F12). Check your system's manual or look for on-screen prompts during boot.

Step 3. In the BIOS/UEFI settings, select Boot, and after selecting the cloned drive, use the appropriate key (usually Page Up/Page Down or +/-) to move it to the top of the boot sequence. This action makes the cloned drive the first boot device.

Change Boot Order

Step 4. Save the changes you made to the boot order. Look for option Exit. Confirm the action when prompted.

After saving the changes, your computer will restart. It should now boot from the cloned drive.

2. Repair MBR or GPT

You can try to repair Master Boot Record (MBR) or GUID Partition Table (GPT) when you encounter Acronis disk clone not bootable by following steps.

Step 1. Use the Windows installation media or a recovery disk to access the Command Prompt. And run following commands.
