“Recently, my Windows 10 computer running slow. I want to replace the system hard drive with a new SSD. I do not want to reinstall Windows so I decided to clone HDD to SSD, and then replace the HDD with the cloned SSD. However, the Windows 10 failed to boot from SSD.”
SSD not booting after clone is a common phenomenon that many users have met before. Why it happened? How to solve it? Here you can fin the answer.
If your Windows 10 won’t boot from SSD after upgrading or cloning system hard drive to SSD, it may because of incorrect boot order. Thus, you need to change the boot mode:
1. Make sure the SSD is connected to your computer.
2. Restart your PC. Press a specific key continuously to enter BIOS Setup (usuallyF2, F8, F12, Del key).
3. When you get into the BIOS Setup, use the arrow keys to select the SSD as the first boot order under Boot tab.
If the SSD is a GPT disk, then you need to make sure the EFI/UEFI boot mode is enabled. And you need to get into BIOS Setup to set it to EFI/UEFI boot mode. Otherwise, you cannot boot from the SSD unless it has been converted to MBR disk.
If the SSD is an MBR disk, then you need to set the boot mode to Legacy. Otherwise, you need to convert MBR to GPT disk so that it can boot from SSD successfully.
If you cloned HDD to SSD but cannot boot from the SSD, that may because of system files lost. Thus, you can take another way to clone system disk to SSD. AOMEI Partition Assistant is a great tool that can help you copy system disk to SSD/HDD safely with a few simple steps.
1. Install AOMEI Partition Assistant to your PC based on Windows 10/8/7, connect the SSD to the PC and make sure it can be detected. Launch the progress. Click More Tools-> Disk Copy Wizard.
2. Select disk copy type: Copy Disk Quickly (recommended) or Sector-by-Sector Copy.
3. Choose the system disk as the source disk.
4. Choose the SSD as the destination disk. Here you need to check the option “Optimize the performance of SSD”.
5. You can edit partitions on the destination disk. Or you can repartition hard drive later.
6. Here will give you a note for how to boot form the clone drive. Read it and click Finish.
7. Finally, click Apply-> Proceed at the toolbar to execute the progress.
After that, you can try to boot from the SSD again.
Another reason for SSD not booting could be the MBR error. And you can try Bootrec.exe to fix SSD not booting after clone.
1. Boot from the repair disc, open Command Prompt.
2. Enter the following commands in order:
bootrec.exe
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /scanos
bootrec.exe /rebuildbcd
If you do not have a repair disc, you can use AOMEI Partition Assistant to fix MBR error in a few simple steps.
Step 1. Using AOMEI Partition Assistant to create a bootable USB drive.
Step 2. Connect the bootable USB drive to your computer with the SSD installed and boot from the bootable USB drive.
Step 3. It will show you the main interface of AOMEI Partition Assistant. Here, right click the SSD, select Rebuild MBR.
Step 4. Set the type of MBR for the current OS. Click OK.
Step 5. Click Apply-> Proceed at the toolbar to start.
Many users are planing to clone didsk from one computer to another computer instead of installing Windows. However, the SSD not booting problem may occur. For this situation, you need to check the connection mode. If the original computer uses IDE mode, the destination computer has to use IDE mode. If the original PC users AHCI, the target PC must use AHCI mode. Otherwise, you cannot boot from the SSD successfully.
for this situation, you’d better Back up the source HDD onto an external storage device using AOMEI Backupper. Then create an AOMEI bootable media to boot the target computer and restore the backup to the destination HDD with Universal Restore option enabled.
