    Here it shows windows cannot be installed to Disk 0 Partition 5. (Reason: The selected disk is of the GPT partition style).
    That is only warning for PC's without UEFI/BIOS firmware.

    I had this issue.

    The whole physical drive needs to formatted via GPT. If the drive has been formatted as a MBR which Windows 7 and before use, this is not compatible with Windows 8 utilising UEFI.

    .. unless you go into BIOS, boot options and change to Legacy thinking about it.

    I have shrinked the HDD space to create 25 GB new drive.

    You are booting the Windows 7 x64 DVD in Legacy mode, to install Windows in Legacy, delete ALL PARTITIONS.

    Make sure you make a System Image of Windows 8 first.

    Dear Theog,
    Thank you for your valuable suggestions and guidance. Now I had taken a windows system image (CP>Windows 7 file Recovery>Create a system image)
    and took a system repair disk (CP>Windows 7 file Recovery>Create a system repair disc>.

    Now I will do as follows correct me if I'm wrong
    1) "Security" tab and disable "Safe Boot"
    2) change "boot mode" from "UEFI" to "CSM"
    3) Delete each volume for win 7 installation

    As the Toshiba laptop with windows 8 pre-installed, please suggest a way to retrieve the genuine product key.
    After this if I need windows 8 back I have to use the repair disk then the windows image right?
