How to format SSD partition to MBR from GPT without formatting entire disk?

[Bove]

Hi
I'm trying to install Win 7 x64 on my SSD partition, but i can't install it because the disk is in GPT format, I already have Ubuntu 14.04 installed on one of the partitions and I wouldn't like to have to format the entire disk.

I found a way to format the disk to MBR, but it formats the entire disk using the CMD from the win7 DVD using the app "Diskpart", any advise on how I should approach this? is formatting disk my only option?

My ssd is the Samsung 840pro 128Gb

Thank you in advance

GPT and MBR applies to the entire disk, you can't have one partition GPT and the other(s) MBR. You will therefore have to repartition and reformat the entire disk.
