"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."

  • 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.

  • Lack of 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.
