Read this article to learn how to fix the cloned SSD not booting issue on Windows 11/10/8/7. If you want to avoid future boot problems, explore an alternative method to clone your HDD to SSD without any issues.
There are a lot of reasons that would cause the SSD won’t boot after clone. I've summarized some common reasons here:
✔ Bad sectors: If the source disk you cloned has bad sectors, it may cause cloned Windows 10/11 SSD won’t boot.
✔ Corrupted system: The system is corrupted during the cloning process, so the cloned drive won't boot.
✔ Missing System Reserved partition: Missed cloning the System Reserved partition.
✔ Missing boot files: The drive letter may have changed while you change HDD to SSD, causing boot files missing. As a result, SSD cannot boot after cloning.
✔ Wrong boot drive: Set the wrong drive to boot from.
✔ Wrong boot mode: Boot mode does not match the cloned disk’s partition style (GPT for UEFI, MBR for Legacy).
After cloning HDD to SSD, if the SSD cannot boot, you can try the following solutions according to your situation:
Use a SATA cable to connect the cloned SSD to your computer instead of a USB connector. Some Windows 10 users successfully booted their PC from the cloned SSD using this method.
In most cases, the active partition should be the primary one where the operating system's boot files reside. If the cloned SSD is not booting on a Windows 10 computer, it may be due to the system partition not being designated as active. You can use Command Prompt to change this.
1. Boot from the old hard drive since the cloned SSD won't boot.
2. Place the SSD in a hard drive enclosure and attach it to the PC.
3. Type “cmd” in the search bar. Right click on Command Prompt and select “Run as administrator”.
4. In the Command Prompt window, type the following commands one by one, pressing Enter after each:
After performing the above commands, restart the computer.
If you cloned the GPT HDD to MBR SSD, or cloned the MBR HDD to GPT SSD, it is necessary to change boot mode from UEFI to Legacy or from Legacy to UEFI. The wrong boot mode will cause the SSD not booting after clone.
To change the boot mode, you can refer to the following to configure it:
1. Continuously press a specific key (usually F2, F8, F12, Del) to enter BIOS Setup.
2. Then, use the arrow keys to select Boot tab. Here, you can select UEFI/BIOS Boot Mode as Legacy or UEFI.
3. Press F10 to save the settings and then exit. Then, restart your computer from the cloned SSD.
Wrong boot device could also cause the cloned drive won't boot. If there is more than one hard drive on your computer, you'd better set boot order manually.
1. Enter BIOS Setup and go to the Boot tab.
2. Set the cloned SSD as the first boot option and press F10 to save and exit.
Your computer should boot successfully now. If not, go to the next solution.
Sometimes, you need to get into Windows recovery environment (Windows RE) to repair Windows Startup if the cloned drive won’t boot in Windows 10/11. The Windows Startup repair will fix some errors and help you boot successfully.
1. Boot from the Windows installation disc. Select Repair your computer.
2. When you get into the "Choose an option" screen, select Troubleshoot -> Advanced Options -> Startup Repair (Windows 11/10/8). Then, it will start to repair the startup problem.
If Windows Startup Repair doesn’t work, you can use Bootrec.exe to fix cloned SSD won’t boot in Windows 11/10/8/7.
1. Boot computer from Windows installation disc. Select Repair your computer -> Troubleshoot -> Advanced Options -> Command Prompt.
2. In the pop-up command prompt, type the following commands to fix Windows 10/11 fails to boot.
