Windows 10: Convert MBR to GPT for current SSD running Windows 10

I got the notification that my PC does not meet current requirement to upgrade to Windows 11. After some research, I found out that my current SSD running W10 is in MBR, which needs to be GPT to satisfy the requirement.Now here is the hard part, is it possible to do a conversion to GPT on my current W10 SSD, or I need to re-install everything from scractch?Appreciate any helps!

Cannot convert GPT to MBR.

Hi Michael,



I suggest you to follow the below steps and check if it helps.

This method you have to backup all your data and delete all partitions and volumes. Then use the
DISKPART command.

• Open command prompt and type in DISKPART and press Enter
• Then type in list disk (Note down the number of disk you want to convert to GPT)
• Then type in select disk number of disk
• Finally type in convert gpt.

Hope the information helps. Do reply if you need further assistance.

 

Converting MBR to GPT

I finally got a new array running, 3TB currently. One disk already had some data and there was an option to create a new array without losing that data. I figured that would safe me time (it didn't) so did it. Converting the whole crap took about 40 hours (not exaggerating) which was rather unexpected. Now I have a 3TB array which needs to be GPT, not MBR. Though converting to GPT can only be done on empty disks. Google so far doesn't come with some tool that can convert disks without losing data, would anyone know of a tool that can do such a thing? I don't feel like breaking the array, copying all data, converting the disk, copying everything back, restoring the array. It would take about 300 years to do that.
