Windows 7: Problem converting GPT parition to MBR on Windows 7 Setup

Problem converting GPT parition to MBR on Windows 7 Setup

Hello everybody,
Today I wanted to reformat my computer with Windows 7 because he was very slow. So I took an official Windows 7 DVD Rom and I started my installation. When I was in the window "Where do you want to install Windows ?" I choosed my partition with 441 GB and I pressed on "reformat" and I had the error "Windows cannot be installed to this disk. The selected disk is of the GPT partition style".

So I searched on the Internet, and I went to a topic on your website (Convert GPT Disk to MBR Disk) and I did all the steps. The problem is that when I do the command "convert mbr" it says me "The specified disk is not convertible. CD-ROM and DVD are examples of non convertible disks".
Maybe I have this error because I don't removed the volume "System" and "Recovery" but I don't think it's a good idea to remove them.
I let some screenshots:





Thank you if you can reply and sorry for my bad english,

Rémi.
