The Windows partition should be converted to GPT format

If you are thinking about installing Windows 10 on your PC, then there is no doubt that you want to do a clean installation. This way, you won’t lose any personal data stored on your hard disk. However, while doing a clean installation, you might notice that the size of your primary partition is quite small. In fact, most people choose to keep just one partition on their hard disk, which is why we often see only one partition displayed during the installation process.

This article explains how you can convert the partition format from MBRD to GPT, which will allow you to increase the size of your primary storage space.

1. Open Command Prompt. Now, enter the following command to launch the Diskpart utility:


2. Type list partitions to check whether you already have a single partition on your computer. If you don’t, then follow step 3 to add another partition.

3. Use the New Simple Volume Wizard to add a second partition. For example, let’s say you want to add a secondary volume named Data. You can do this by typing select volume D:, where “D:” represents the letter D followed by a colon (:), and press Enter. Once done, type exit to close the wizard.

4. Check the status of the newly added partition. Type list volumes again to verify that the partition exists.

5. Once the process is complete, you can restart your computer and choose the option to start from the DVD/CD Drive. Then follow the instructions on the screen to finish the setup.

Ensure that the hard drive is set as the first boot device

Setting the hard disk as the primary boot device is easy. You just need to do it once and then it stays there forever. If you want to make sure that the computer boots up into Windows 10, you’ll need to repeat this process every time you turn on your PC. Here are the steps you need to take to set the hard drive as your primary boot device.

1. Insert the installation media into the optical drive.

2. When prompted, select “Install now.”

3. After the installation completes, restart your computer.

4. Select the option to enter BIOS settings.

5. Locate the Advanced menu and press F10.

Activate your partition with Diskpart

In Windows 10 there are three ways you can make a partition active. You can use the built-in command prompt tool called disk part. This method requires no additional software and it works like magic.

1. Open Command Prompt window. Type “diskpart”. Press Enter key.

2. List partitions. Type “list disk”. Press Enter key. Note down the number of disks listed. In our case, we have one hard disk with four partitions. We’ll call them Partition A, B, C, and D respectively.

3. Create a partition. Type “create partition primary c:” /size100MB”,f:” /index0″. Press Enter key. Here, we’re creating a 100 MB partition named C:.

4. Format the partition. Type “format fsntfs quick”. Press Enter key. If everything went well, you should see the following output:

5. Mount the partition. Type “mount volume 0”. Press Enter key. Now, you can access the newly formatted partition.

6. Activate the partition. Type “activate”. Press Enter key. Your partition is now activated.
