I have a Toshiba and I want to install Windows 7 on it. My firmware is UEFI. I have disabled the secure boot and I have enabled the Legacy support.Before the installation of Windows 7 i have partitioned my hard disk with MBR with gparted.
I then try to install Windows on it. The problem is that Windows during the installation converts my hard disk to GPT automatically. Why? How can i solve this problem?

From UEFI Wikipedia page:
Windows installation booted from EFI, does not allow installation on MBR disks and vice versa.
EFI installation needs EFI partition scheme TO BOOT (correct me if I'm wrong)
like:
But, it can load windows from another MBR disk (or VHD) in CSM mode. So, to accomplish this, you need at least 2 disks, or 1 physical GPT disk, containing a Virtual MBR disk.
