MBR TO GPT - INFORMATION

IMPORTANT INFORMATION ABOUT THE MBR2GPT TOOL

 

Although disks configured with MBR-style partition can have up to four primary partitions, for this process to work the disk you want to convert can't have more than three partitions, because one allocation is needed to create the new UEFI system partition.

 

You can use the MBR2GPT tool to convert hard drives and solid state drives (SSD) with an earlier version of Windows 10 installed, including Anniversary Update (version 1607), November Update (version 1511), and the initial version of Windows 10 (1507). 

However, you must use the tool on a computer running Windows 10 version 1703 or later, and then perform the conversion.

It's not possible to convert disks with older versions of the OS, such as Windows 8.x and Windows 7, but you can upgrade to Windows 10, and then use the tool to convert from MBR to GPT.

If you're converting a hard drive or SSD with BitLocker enabled, you must suspend the encryption protection before using these steps. And to resume the protection after the conversion, you must remove the current protectors and recreate them again.

Wrapping things up

 

It's been possible for a long time to convert an MBR disk to GPT to switch from BIOS to UEFI, but now you can make the conversion in minutes without wasting time doing a clean install of Windows 10 and backing up your data. This tool not only comes in handy for anyone who wants to make their PCs a bit more secure and faster, but it'll also benefit organizations that want to significantly reduce time and the cost to move to a more advanced firmware.
