Convert MBR TO GPT Without Data Loss Windows 10 hard drive partitions without losing data for free. There’s a lot of tools out there but they charge money for it. But we going to show you how to do it inside windows 10 for free.
Differences Between MBR vs GPT Drive – Why You Should Choose GPT over MBR ?
MBR is the old way of doing things while GPT is the new version of everything your computer MBR drives is that they cannot have more than about two and a half terabytes of information on the same drive. It just won’t let you partition it GPT though it lets you be able to make partitions up to pretty much the sky’s the limit because zettabytes of information.
MBR you can’t have a three terabyte partition and not even a three terabyte partition where you could have a two terabyte partition and a one terabyte partition. But you only get the two terabytes you have one terabyte of your drive that you actually cannot use whatsoever you pay all this money for three terabytes and You can’t even use all of it so that’s why you want to go GPT.
The other reason you want to go GPT is because everything in the future is going to be GPT only if you’re running an MBR hard drive as your primary as your boot drive it has to run the BIOS firmware UEFI firmware is what GPT requires if you want to boot using a GPT drive you have to boot using UEFI if you want to boot an MBR drive you have to boot bios lastly
Convert MBR TO GPT Without Data Loss Windows 10
1. Check Disk Properties (MBR to GPT)
So right click on the “Start” button and click on “Disk management” so you can see this.
As you can see this our drives here it’s “Disk 0” yours might be called something else. Right click on it and go to “Properties” once we go there click on “Volumes” and should see partition style.
It says “Master Boot Record (MBR)” for this drive we need to convert this to “GPT”.
2. Download Microsoft Tool (MBR to GPT)
If you want to upgrade to windows 10 you’re going to need to convert this to “GPT”. So if we checkout Microsoft website here they have a tool called “MBR2GPT.EXE”. it’s an executable file that’s inside windows 10.
It will allow you to convert from “MBR to GPT” without losing any data. Which is exactly what we want to do. If we scroll down the page it tells us some examples on how to use the tool.
MBR to GPT
But don’t worry we going to show you exactly what to do and how to do it. So let’s crack on. Go to “File explorer” and click on “This PC” then go inside “Local Disk C”.
And select “Windows” folder scroll down and look for “System32” folder. Open that folder scroll down and look for “MBR2GPT” file. The actual file is in the system32 area is built into windows.
Command Prompt (MBR to GPT)
So let’s go ahead and open up the “Command prompt”. If you don’t have command prompt you can look for “PowerShell”.
Just type in search box and open it “Run as administration” click on “Yes” to the user account control. Once you open the command prompt. First command we’re going to type in is this: mbr2gpt/validate/disk:0/allowFullOS
This is going to validate our disk to make sure that it is “MBR”. Just type this given command inside the command prompt and hit “Enter”.
Make sure that the disk:0 is actually the disk that you are checking if it’s not then it’s going to come up with an error. If not, then you can see the message written “Validation Completed Successfully”.
So if you’re disc 1 you need to make sure you change “disk:0 to disk:1” or vice versa whatever disk you’re using. Let’s go ahead and put the second command in which is: mbr2gpt/convert/disk:0/allowFullOS
This is to convert the disk from MBR to GPT. Once you enter the command hit “Enter” and this will start the process and you can see it’s don’t all what it needs to here.
BIOS Setting (MBR to GPT)
And you should see at the very bottom here since before the new system can boot properly you need to switch the firmware to boot to UEFI mode.
That is your BIOS you need to go to the bios normally to enter the bios you restart the PC and you keep tapping the delete key. Keep tapping the delete key on restart and it will enter the “BIOS”.
Once you restart your computer you should see something looking like this. This is the BIOS screen and you will see in the center here under settings.
There is a boot mode selection and we need to make sure that is set to “UEFI”, once you done this you can then start the PC up. And you should be able to then boot to you windows 10 operating system. After start up your operating system you will be able to update to windows 11.
You can’t upgrade to windows 11 with an MBR partition system so you need to go to the GPT. Check out your data you may still got all the documents on the PC and just quickly make sure that the drive is converted to GPT.
So right click on “Start menu” and select “Disk Management” go to “Disk:0” the drive which you have converted right on that and select “Properties”.
It will open the properties windows inside that go to “Volume Tab” where you can see the partition style which is now changed. To “GUID Partition Table (GPT)”.
If it shows you the drive name “System Reserved” in “This PC” windows if you don’t want, you can hide it. Some of you don’t want it visible. Go back to “Disk management” and you should see the “System Reserved” here. So what we going to do is hide this.
The way we going to hide this is by changing the drive letter and paths so right click on “System reserve” drive and select “Change drive letter and paths”. After that you need to select “Remove” and select “Yes” and that should hide that drive and that won’t be visible.
That’s how you can convert from MBR to GPT without losing any year data and doing it for free in windows 10.
