February 1, 2019

GParted is a great tool that can help you manage disk(s) on Windows. Here you can learn how to use it to convert MBR to GPT without losing data.

Scenario

“Hey guys! I am attempting to load Windows 7 on this PC but it’s asking for GPT. I know that I need to convert my MBR to GPT disk so that it can work normally. But how to do it? I have Gparted tool, and I want to know how GParted convert MBR to GPT? Is there anyone who know the operation steps? Other effective ways are also acclaimed. Thank you!”

Besides the scenario, there are so many situations you need to convert MBR to GPT disk. For example, the 3TB hard drive only shows 2TB, which is because of the hard drive is an MBR and MBR disk supports up to 2TB capacity. If you want to fully use the hard drive, you need to convert MBR to GPT, which supports disk larger than 2TB capacity. Or if you need more than 4 primary partitions on the hard drive, you need to convert MBR disk to GPT because the MBR disk only supports up to 4 primary partitions while GPT disk allows you to create 128 primary partitions on the hard drive. You may have other situations that need to convert MBR to GPT. If you do not know how to do it, follow this article to learn how to convert MBR to GPT without losing data.
