About the target disk
• The target disk has different partition style of original hard drive. In general, many disk cloning software only allows you to clone disk with the same partition style. If not, the process will fail.
• The target disk is smaller than original disk. Honestly, most disk cloning software only clone disk to larger disk. So you need to delete the useless installed programs or large files to free up space.
• The target disk is not the default boot disk in BIOS. Usually, your computer can only boot from the default boot disk, also called first boot option. If not, please set the boot priority for target disk and press “F10” to save the changes.
• The cloned disk only has operating system. To boot windows 10/11 from cloned drive, not only the operating system, but also other boot related partition or files are required. To check it, you can go to disk management and see if there are system reserved partition or EFI system partition.
About other problems
• Cloning hard drive in Windows 10 with other externally connected devices, such as, bootable USB or CD/DVD. So, the disk cloning software may clone the boot partition to other external device instead of your target disk.
• The computer does not support UEFI boot mode. If your computer was bought a long time ago, it may not support the newer boot mode UEFI. Meanwhile, most of the current disk are GPT, which requires UEFI boot mode. Therefore, you need to convert GPT to MBR without data loss ahead of time.
• The master boot record is damaged. If your situation is different from above, Windows 10 clone not bootable may be caused by corrupted MBR or BCD. You can boot your computer using installation disk or recovery disk, press “Shift + F10” to open command prompt, then type the following commands and hit Enter.
