Guide 2: Convert MBR to GPT with DiskPart Command Lines

Windows OS has an internal disk utility feature called DiskPart that you can use to convert a disk from MBR to GPT. Compared to a third-party application, such as EaseUS Partition Master, this method is a bit slow. 

Moreover, you also need to use the Windows installation media to enter Command Prompt to execute this operation. Here’s how you can perform this activity.

Step 1. Go to the command prompt by pressing Shift and F10 keys on the Windows installation screen.

Step 2. Apply the following commands to execute the conversion:

• diskpart
• list disk
• select disk (enter the number of the disk in front of this command)
• clean 
• convert gpt

Now, proceed with the Windows installation process. You will not get this anymore while installing the Windows OS.

#2. Disable UEFI and Enable Legacy Boot Mode in BIOS 

Another way to fix this error is to enable the Legacy Boot Mode in the BIOS settings. Disabling the UEFI mode will no longer show the error, and you will be able to install the Windows OS. Here’s the step-by-step guide to performing this activity in the BIOS settings.

Step 1. Restart the computer and enter the BIOS setting. Entering the BIOS setting varies for different Brands, such as HP and Dell. Make sure you hit the correct buttons.

Step 2. Inside the BIOS settings, go to Boot Devices. Here, you will find the Boot order where you can disable EFI sources. Besides this, you can also change the DVD drive from UEFI to SATA or Legacy Mode for this purpose.

Step 3. Ultimately, save changes and exit to proceed with the Windows installation.

You will no longer get the error while installing Windows on your system.

Overview of The Selected Disk Has an MBR Partition Table

Before we jump straight into the efficient solutions for this problem, it's essential to know what exactly this error is and why it occurs. 

It is a storage disk-related error that stops you from installing the Windows OS. It mainly occurs when there is a conflict between your BIOS type and hard drive partition style. A system with UEFI BIOS only supports GPT partition-style disks. However, Legacy BIOS supports MBR partition style. 

So, when the disk uses Master Boot Record (MBR) and the system is on UEFI BIOS, it simply leads to this error. In the presence of this error, you can't proceed further with the remaining Windows installation process.

Tips to Keep Computer from Selected Disk Has an MBR Partition Table Error

Although you can always fix this error with a little effort, it’s always better to avoid such errors in the first instance. Here are a few tips to keep your computer away from this error for Windows installation. These tips include:

2. Check the computer compatibility with different operating systems, such as Windows and Linux. For this purpose, you can read the product description of the system.

3. Check the disk on which you're going to install the operating system has the acceptable partitioning style for a smooth process of installation. If the disk doesn't have an acceptable partitioning style, it will support further installation.
