    Converting GPT disk to MBR disk.

    When i convert the disk says that the disk needs to be formatted.Does that format everything or only not the windows files (so the vital-to-run files :p )??

    You need 3rd party software to do it non-destructively.

    I have paragon HDM 12 PRO and HDM 12 business.

    They do cheaper products as well. Maybe one of the trial versions will allow that function.

    Take note of Step 11 for Windows 7.
    Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.
