How to Convert MBR to GPT without Data Loss in Windows 7
What Are MBR Disk and GPT Disk
The hard disk is a kind of storage media installed in the computer. In general, there are two hard disk styles: MBR disk and GPT disk. MBR which is short for Master Boot Record and GPT which is short for GUID Partitioning Table are two different disk partition tables. MBR disk only supports hard disk no larger than 2 TB and up to four primary partitions or three primary partitions plus one extend partition; GPT disk can manage hard disk larger than 2TB and supports up to 128 primary partitions in Windows Operating System. Besides, MBR disk boots from legacy BIOS, while GPT disk boots from UEFI.

MBR disk is widely used nowadays. But in the era of information explosion, more and more data will be saved to the hard disk. With time goes by, the hard disk will be run out of space. Hard disks larger than 2TB emerge to satisfy your needs. So GPT disks become the trend. On the other hand, if you want to create more than four primary partitions on your hard disk, or you have to boot your hard disk from UEFI, the only thing you could do is to convert MBR disk to GPT disk. Is there any way which can convert MBR to GPT free in Windows 7? The answer is yes. Let's look the following content.
How to Convert MBR Disk to GPT Disk in Windows 7
There are three tools you can use to convert MBR disk to GPT disk in Windows 7, and they are third-party partition manager, Disk Management, and Diskpart.
Convert MBR to GPT without Data Loss in Windows 7
When it comes to the partition table type conversion, you probably ask: is there any tool to convert MBR to GPT Windows 7 without data loss? Of course. To make things easier, technicians designed some pieces of partition management software which can convert MBR to GPT without data loss. Among all these software, MiniTool Partition Wizard is a good choice.

Step 2. This interface is the preview of conversion result, and you need to press "Apply" to save the change.
- If you choose to use Professional Edition to convert your OS disk to GPT, please ensure your motherboard supports GPT. And MiniTool Partition Wizard will remind you to enable UEFI Boot Mode from BIOS after clicking "Apply" button so that your Windows 7 can boot from GPT disk successfully.
- You can't install Windows in MBR disk when you are using EFI motherboard, and you can't install Windows in GPT disk when you are using legacy BIOS motherboard. To solve these issues, you can refer to this article: Windows Cannot Be Installed to a Disk? Here Are Solutions.
Then you can see that the target disk is converted to GPT disk in Windows 7, and all data are kept well in it. This way is quick, reliable and effective. And the most important is that you can keep all your data safe. It saves a lot of troubles for you. With the help of MiniTool Partition Wizard, it is very easy to convert MBR to GPT without data loss in Windows 7.
Convert MBR Disk to GPT Disk by Disk Management
In addition to using the third-party partition manager to do this conversion, some of you probably choose to use Windows 7 Disk Management.
1. Get into the disk management interface, select the target hard disk and delete all partitions in it with "Delete Volume".
2. Right-click on the target hard disk and select "Convert to GPT Disk".
Then you can discover that the MBR disk is converted to GPT disk successfully.
Please notice that if there is any partition on the target disk, the function of "Convert to GPT Disk" will be grayed out.
Convert MBR to GPT Diskpart
Besides, another free tool can be used to convert to GPT disk in Windows 7, which is Diskpart.
1. Firstly, you should press Windows 7 "Start" badge, type "diskpart" in the search bar and press "Enter" to get the diskpart interface.
2. Then type "list disk", "select disk n"(n means disk number), "clean" and "convert gpt" respectively, and press "Enter" after every typing.
Unfortunately, the above two methods of converting MBR to GPT can cause data loss, and you have to spend time on backing up your important data stored on the target disk. This process may cause a long time if the target disk contains large size data. So they are not the ideal ways. In this case, MiniTool Partition Wizard is really worthy of being recommended since it can convert MBR to GPT without data loss in Windows 7.
In summary, MiniTool Partition Wizard can not only convert MBR to GPT Windows 7 without data loss but also convert GPT to MBR without losing data. If you have the need to do the conversion between MBR and GPT or other partition issues, don't hesitate to use MiniTool Partition Wizard.
