Problem: Cloned drive won’t boot in Windows 10

Sometimes we may clone hard drive to SSD for better performance, clone smaller drive to larger drive for more capacity, or clone internal drive to external as a backup. However, the issue that cloned drive won’t boot occurs in Windows 11/10/8/7 every now and then. Here is a live example from forum:

I bought a SSD with the intent of cloning my HDD, and after some trial and error, got the process completed. Through the USB to SATA cable, the computer is recognizing the new drive and all the data. But when I swapped the drives, the BIOS says it can't boot because there's no hard drive.

What are the possible causes of this problem and how can we make cloned SSD bootable?

Cloned SSD Won't Boot

Why cloned SSD won’t boot

What causes your cloned drive not to boot? Here I have summarized some common reasons:

How to make cloned drive bootable in Windows 10/11

Given the possible causes of cloned drive won't boot issue, the corresponding solutions are also provided below. But before anything, it's best to make sure that the cloning process was successful and error-free.

Sometimes, cloning tools may miss copying the boot sector or the necessary partition information. Make sure that the boot sector and relevant partitions were properly cloned.

Next, I will introduce some common methods to make sure the computer can boot from the cloned drive.

Way 1. Change boot order to boot from the cloned SSD

If there are more than one hard drive on your computer, when you boot failed, you need to consider whether it is wrong of your boot device.

If it is, you need to press the specific key (usually F2, F8, F12,Del) to enter BIOS or UEFI settings, and change the boot order to boot from the cloned SSD.

Way 2. Switch BIOS mode to UEFI (GPT) or Legacy (MBR)

One thing to be noted is that MBR disk works with Legacy BIOS while GPT disk works with UEFI. So if you need to clone a MBR HDD to GPT SSD, or vice versa, it is necessary to switch the boot mode accordingly. The wrong boot mode will cause the SSD not booting after clone.

To change the boot mode, you need to enter BIOS during startup as well, then select the boot mode (usually under Boot tab) as Legacy or UEFI.

Change Boot Mode

*If your computer only supports Legacy BIOS mode, you can convert GPT to MBR to make it compatible.

Way 3. Remove/wipe the previous drive

Many cloning software have their own SID (System Identifier) generation utilities, but there are some exceptions. If the software copies the drive’s unique SID as well, it may end up confusing the system, since it won’t know where to boot from.

In this case, you can make only one of the drives usable by removing or wiping the original drive.

Way 4. Fix corrupted BCD

If the cloned drive fails to boot because of corrupted BCD, you can access Windows recovery environment, and use Startup Repair (Advanced options > Troubleshoot > Advanced Options) to fix it, or run bootrec.exe commands in Command Prompt to rebuild BCD:

Bootrec /fixmbr
Bootrec /fixboot
Bootrec /scanos
Bootrec /rebuildbcd

Fix Windows 7 Startup Repair Loop via Command Prompt: CHKDSK or Bootrec

Way 5. Restart the cloning process in an error-free way

If you have encountered errors during the cloning process, you can either choose to fix the error, or restart the cloning process with professional cloning tools.

There are also some considerations before, during and after the cloning process that can help you avoid the unbootable situation. I will give you more details below.

In this way, we can certainly enjoy a better cloning speed and avoid many potential booting problems. And things will become much easier to clone larger drive to smaller drive or vice versa.

Steps of Windows 10 cloning boot drive

✍Notes:
▪ The target disk will be overwritten after cloning, so it's recommended to perform data backup in advance.
▪ The Professional edition supports data disks and system disksof all brands and partition styles. You can clone MBR to MBR/MBR to GPT or GPT to GPT/GPT to MBR directly. But you still need to make sure the partition style of the target disk is compatible with the boot mode.

Step 1. Connect the SSD to your computer and make sure it can be detected. Then download Qiling Disk Master, install and launch it.

*Clone features in free trial can only be demonstrated. Please upgrade for full functionality.
