Need help to clone a Windows installation disk to a 2TB hard drive: MBR to GPT

"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.
