Here we introduce you the simplest way ever to migrate OS MBR to GPT without changing partition style. Follow the tutorial guide and clone Windows 10/8/7 system disk and boot disk from MBR disk to GPT disk within 3 steps.

"Hi, do I need to convert GPT to MBR first if clone system drive from one MBR disk to another GPT disk? Now I plan to clone a Windows 7 installation disk (partition table MBR) to a 2TB (newly bought, not used yet) GPT hard drive, what's the best and fastest way to make it happen?"

There are many ways to migrate OS from HDD to SSD or migrate OS between two same type hard drives, for example, you can just image the system drive and restore the image to the target drive, or just clone one to another. The former method is relatively complex compared with the latter, thus in the following, we just focus on the "clone" way to help OS migration.

How to clone MBR OS to GPT disk

To migrate OS from MBR disk to a GPT disk, there are some tips you should follow.

  • The target GPT disk should be bigger enough or at least with an equal size to that of the source MBR system disk.
  • Make sure the target GPT disk is empty with no partitions and data on it, or else you need to delete all partitions on it. You'd better backup the data first before clearing them all.
