Cloned SSD won’t boot in Windows 10

My computer is running Windows 10. Yesterday, I cloned C drive to G drive(SSD) via a third-party clone software. However, when I try to boot from G drive, I find that the cloned SSD is not bootable. What should I do to make the cloned G drive bootable just like C drive? Can you give me some suggestions? Thanks in advance.

Why cloned SSD won’t boot and how to solve it?

There are some common reasons that may cause SSD won't boot after clone, you can refer to these reasons and try to solve your problem:

  • Set the wrong drive to boot from. You need to get into BIOS and change the boot order. Then, press F10 to save the change you did and boot from the cloned SSD.

  • The system may be corrupted during the cloning process. This problem may be caused by the clone software. You need to choose a professional software.

  • Missed cloning the “system reserved” partition. You need to choose a professional clone software that can completely clone all partitions including "system reserved" partition.

  • GPT/MBR conflict. If you cloned the GPT HDD to MBR SSD or cloned the MBR HDD to GPT SSD, it is necessary to change the boot mode from UEFI to Legacy or from Legacy to UEFI.
