MBR to GPT issue

[OCNewbee]

Goal:

convert my ssd from MBR to GPT so I can use resizable bar

*AFAIK resizable bar needs CSM disabled.

MBR does not function with CSM disabled.

 

Problems:

1) I do not want to format my windows

2) SSD hard drive partitions are gone (I deleted the recovery partition and merged it with the main partition)

    A) As such, I cannot use programs like mbr2gpt

3) the SSD has the system files (windows 10 on it) so many programs will not let me change it

4) the SSD has the page files so many programs will not let me change it 

 

Methods I have tried:

1) cannot use mbr2gpt because I deleted and merged the windows recovery partition with the main partition.

2) tried using partition programs. (It does not work because the drive that I want to change from mbr to GPT contains pagefile)

 

I think my only option now is to reinstall windows...which is the last thing I want to do....I hope some genius here can help me. 

Thanks.

You might be able to get diskpart to do it for you, 

So, run CMD as administrator, run "diskpart", then "list disk", then take note of the disk you want. 

Run "select disk [number you took note of]", then "convert gpt"

Yeah thanx but doesnt work. Already tried it. I think it said something about pagefile.

Could you try it again and report the error?

It might be that you will need to disable the pagefile to do it.

Or create a installation media and use it's CMD to do it from there, as it won't be the booted system partition, it might work.

Thanks man but i decided to wait until asus releases a final version of their bios for their rebar. But the installation media and cmd ideas sounds very smart!
