Converting Windows 10 SSD from MRB to GPT to use UEFI?

Hi,

I'm looking to convert my Kingston V300 SSD which has Windows 10 on it from MRB to GPT so I can boot in UEFI mode (which I currently cannot do), and hopefully see performance improvements. Can I do this? If so, how? Thanks for any help.

 

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.

 

convert MBR to GPT disk

convert mbr to gpt

There is a way to convert mbr to gpt without data loss. clean command deletes all datas inside the disk, so dont use this command

boot with windows dvd , and get into command prompt

type diskpart , find the disk number , which is need to convert mbr to gpt

say disk number is 0

exit diskpart

type below command in command prompt

mbr2gpt /convert /disk:0

wait for some minutes to complete , once you get commpleted successfuly means, exit and close ,

shutdown the pc , remove windows dvd

important

After the disk has been converted to GPT partition style, the firmware must be reconfigured to boot in UEFI mode.


Make sure that your device supports UEFI before attempting to convert the disk.
