Preparation 1: Check If Windows Supports both Legacy and UEFI Boot Mode 

Before cloning the Windows OS from MBR to GPT, you need to prepare your computer and disk for the procedure. Here is something for you to get ready:

• Confirm if the computer supports Legacy and UEFI boot modes. 
• If not, you'll need to convert the GPT to MBR to ensure Windows is bootable after cloning.

How Can You Check if Your PC Supports Legacy and UEFI Boot Modes?

You can check this condition by using the following steps:

Step 1: Start with the Start panel and locate 'System Information.' 

Step 2: Under the BIOS mode, if you can see Legacy, your PC has BIOS.

Step 3: If the PC has UEFI, then it is UEFI.

Tutorial: How to Clone Windows from MBR to GPT 

Being a multi-faceted software EaseUS Partition Master provides 4K alignment partition and dynamic disk management. It also helps in checking and fixing disk partitions. To seek help for cloning Windows from MBR to GPT, you can follow the:

1. Guide 1: If your Computer supports UEFI boot mode.
2. Guide 2: If your Computer does not support UEFI boot mode.

Guide 1. Clone Windows from MBR to GPT If Computer Supports UEFI 

If your PC supports UEFI boot mode, you can successfully clone Windows from MBR to GPT using the following guide.

1. Clone Windows from MBR to GPT

EaseUS Partition Master has a Disk Converter feature that assists with converting disk between MBR to GPT without making you suffer any data loss. Download this software immediately on your PC and let it help you with the required task.

Steps to Follow: 

Step 1. Launch EaseUS Partition Master, go to the Disk Clone tab, select "Clone OS Disk" and click "Next". 

Step 2. Select the target new drive where you want to clone the OS to, and click "Next".

Click "Yes" to confirm that you want to continue the OS disk cloning process.

Step 3. View the disk layout, and click "Start" to begin the OS cloning process.

Step 4. When the process completes, you'll see a confirming message, asking "if you want to start up computer from the clone target disk". 

• Reboot Now means to reboot your PC and configure the computer to boot OS from the new disk immediately.
• Done means you want to make the changes later. 

2. Change Windows Legacy Boot Mode to UEFI

Once you are done verifying that your system can run Legacy BIOS and you have completed the backup of your data, you can proceed with the conversion process. The steps of turning on UEFI may be different for different computers. You can make a configuration of your device by following the given steps:

Step 1: First, as soon as your PC starts entering the EFI setup menu, keep pressing a particular key repeatedly. As a usual practice for desktops, Del is used, whereas, for laptops, F2 is used. If you need clarification about which key to press, tap on the Esc key to get the whole menu and then tap on BIOS Setup.

Step 2: Usually, you will be able to find the UEFI boot or Legacy mode configuration by tapping on the Boot tab. From here, you will be able to disable Legacy along with enabling UEFI.

Step 3: Then save the settings by tapping the 'F10' key and exit the setup.

Guide 2. Clone Windows from MBR to GPT If Computer Doesn't Support UEFI 

If your PC does not support UEFI, you can convert the target GPT disk to MBR with EaseUS Partition Master and then clone the OS.

1. Convert GPT to MBR At First

Step 1. Install and launch EaseUS Partition Master on your computer, go to the Disk Converter section.

Step 2. Select "Convert GPT to MBR" and click "Next" to continue.

Step 3. Select the target GPT disk that you want to convert to MBR, and click "Convert" to start the conversion.

2. Clone Windows between Two Disks

Note that the process is exactly the same as shown in GUIDE 1. You can then directly refer to the respective guidelines listed to clone Windows with success.

Guide 3. Clone Windows from MBR to GPT with MBR2GPT

The MBR2GPT program in Windows enables the transformation of a disk from Master Boot Record (MBR) to GUID Partition Table (GPT) partition style. If you want to prepare disks for a Windows 11 upgrade, MBR2GPT is a good choice for disk conversion because it does not delete or modify the existing data on the disk. 

Step 1. Open Command Prompt as Administrator:

• Type cmd in the search bar > right-click Command Prompt > select Run as administrator to open the Command Prompt window.

Step 2. Validate the disk:

• Type mbr2gpt /validate /allowFullOS > press Enter. This command determines whether the disk is eligible for conversion to GPT. If validation fails, you will need to resolve the issues before continuing.

Step 3. Convert the disk:

• If validation is successful, type mbr2gpt /convert /allowFullOS > press Enter. Please wait for the disk conversion process. 

Bonus Tip: Make Windows Bootable on GPT Disk 

Once you confirm that your PC supports UEFI, you can change the boot drive through BIOS settings. For example, you can directly initialize new disks to GPT with cloned Windows OS as the boot drive. For this, a significant step is to make cloned SSD bootable on your Windows PC. To initiate this process, you must change the boot drive order in BIOS.

You can follow the steps for carrying out the process here:

Step 1: First, restart your PC by tapping on F2 or F8, or F11 keys. You can also tap on the Del key to enter the BIOS environment.

Step 2: Make settings for cloned SSD as the boot drive in BIOS in the boot section.

Step 3: Then save the amendments you made and finish the process by restarting your PC.

With this, you can boot the computer successfully from the SSD.
