How To Convert MBR to GPT During Windows Installation

Windows 10 makes it easier to switch from legacy BIOS to UEFI using the new MBR2GPT disk conversion tool included with the Creators Update. One of the most important parts of your PC is the BIOS, which is the code that sits on a chip on the motherboard, linking the software to the hardware.

Computers have been using BIOS for a long time, but it had a lot of limitations with today's hardware, such as drive support, where BIOS limits you to partitions less than 2TB. This was alright for a while, but it was obvious something else was needed, which is why UEFI was introduced.

UEFI is what replaces BIOS, and it adds a number of other benefits, including faster startup, sleep, resume, and shutdown times. In addition, and perhaps more importantly, it allows you to take advantage of new security features on Windows 10. "Device Guard" give you more advanced controls for application access.

In the Creators Update, Windows 10 introduces a new command-line utility called MBR2GPT that lets you convert a disk formatted using Master Boot Record (MBR) to GUID Partition Table (GPT)-style partition without modifying or deleting that data stored on disk, which is a requirement to move to UEFI mode.

Can I ask something? Your methods is working, but suddenly the disk I used for installation formating itself and all my data has been erased, how can I recover it?

[giovaniiiiii]

after converting the HDD and installing windows, should we convert it back to MBR for partition the HDD? or the GPT should do just fine?
