There are many situations where you need to clone a hard drive on Windows 10 computers. For example, you want to clone a small hard drive to a larger one for more storage space, you tend to upgrade HDD to SSD for better performance, or you just want to make a backup of the hard drive, etc.
However, it's reported that people are easily troubled by the "cloned SSD won't boot Windows 10" issue. Here is a live example:
"Hello, I'm attempting to upgrade my Windows 10 from an HDD to an SSD, both 1TB in size. My goal is to have my SSD as my main boot drive and my HDD as a storage drive for my exceptionally large media files. I've already cloned my original hard drive and figured out how to boot from my SSD, but unfortunately, I failed to boot it and my computer remains stuck on a black screen with a flashing white cursor in the top left."
Luckily, this post explains why SSD not booting after clone Windows 10 and offers six effective solutions to this issue. Keep reading.
There are a lot of reasons behind the booting failure. Below is a list of all possible causes:
➹ The cloned SSD is connected as an external hard drive. ➹ The cloned SSD is not set as the boot disk. ➹ BIOS boot mode is not compatible with the cloned SSD. ➹ The source disk has bad sectors. ➹ The system partition is not active. ➹ The system is corrupted during the cloning process. ➹ The cloned SSD needs specific drivers. ➹ ......
If you are unable to boot from cloned SSD, you can try the following step-by-step guides to make the cloned SSD bootable successfully and normally.
Not all external disks can be booted smoothly. Instead of using a USB cable, you can connect your computer to the cloned SSD with a SATA cable, and restart the computer to see whether the issue is fixed. If not, continue with solution 2.
If the cloned SSD is the first boot option in BIOS, how can you boot from it in the first place? Thus, you have to access BIOS Setup and change the boot order to set the cloned SSD as the boot hard drive. Follow the below steps to get it done:
Step 1. Restart the PC. When the startup screen appears, continuously press a specific key (usually F2, F8, F12, Del) to enter BIOS Setup.
Step 2. After entering BIOS, select the Boot tap with the arrow keys and select the SSD as the first boot option.
Step 3. Press F10 to save and exit BIOS. And restart your computer again.
MBR and GPT are the two sorts of partition styles for hard drives and BIOS and UEFI are the two boot modes on the motherboard. Usually, the MBR partition scheme is for BIOS and GPT is for UEFI. If the partition style of the cloned SSD is incompatible with the boot mode of your computer, the "cloned SSD won't boot Windows 10" shows up.
Therefore, you must enter BIOS Setup to select the right boot mode for your cloned SSD. Here are the steps:
Step 1. Check the partition style of the cloned SSD and confirm your motherboard supports BIOS or UEFI.
Step 2. If your SSD is MBR while your boot mode only supports UEFI, you can convert the SSD from MBR to GPT.
Step 3. Enter the BIOS utility as in solution 2.
Step 4. Select "UEFI/ BIOS Boot Mode" from the "Boot" tap with the arrow keys. Enter the code. Then, choose "Legacy" or "UEFI" according to the partition type of SSD.
Step 5. To save the change, press F10. After that, restart your computer to see if it’s still unable to boot from cloned SSD.
Usually, the boot files about the operating system are stored in the primary partition. If the system partition is not set as an active partition, Windows 10 computer won't boot from the cloned SSD after cloning. Here is how to set the system partition active via the command line:
Step 1. Since the cloned SSD won't boot, boot from the old hard drive this time.
Step 2. Once you've booted from the old hard drive, hit "Win + R" to open the Run box, then type "diskpart" into it and hit "Enter" to open the diskpart.exe tool.
Step 3. In the DiskPart Window, type the commands below and press "Enter" to execute the operations.
List disk
Select disk X ( Here "X" is the disk number of SSD)
List partition
Select partition X ( "X" refers to the system partition number on the SSD)
Active
The Windows Startup repair is a way to fix some computer issues like the Windows 11 white screen of death. So you can get into the Windows recovery environment (Windows RE) to repair the cloned SSD won't boot Windows 10 or other Windows systems.

Step 2. When you get into the "Advanced Options" window, select "Troubleshoot" > "Advanced Options" > "Startup Repair". Then, it will start to repair the startup problem.
If Windows Startup Repair doesn't work, try Bootrec.exe to fix the "clone HDD to SSD not booting" issue in Windows 11/10/8/7.
Step 1. The same in solution 5, when getting into the Troubleshoot menu, choose "Command Prompt".
Step 2. Type the below commands and press "Enter".
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /scanos
bootrec.exe /rebuildbcd
