How to make available converting MBR to GPT on Win7 or Part. Wizard?

This problem I coudnt find at this Forum neither Google so that I wrote it here...


Im an ordinary user. By mistake ive created 2 unallocated partitions on a 3T HDD that I meant to be using only as a storage HDD.

I heard about the Partition Wizard Bootable CD so I booted with it to apply the changes that I want which is: To make those 2 unallocated spaces become one, format and end of story.


Then it says my HDD is on MBR mode so that I couldnt do anything, the right mouse at the option convert MBR to GPT isnt available.

On Windows at Disk Management/Storage, no options for converting MBR to GPT as well.

Whats the solution for this puzzle? Using some another software out there? which would u suggest?

1) Clean the HDD.
Disk - Clean and Clean All with Diskpart Command

2) OPEN Disk Management & set GPT.



3) Partition to suit.
