    Windows back up and multi-OS installation


    Hi,

    I have a Toshiba laptop with windows 8 pre-installed in it. I would like to take a system image including OS, drivers and software's please assist. After that need to install windows 7 keeping windows 8 as it is. In case of failure, this image can be restored right?

    If I want to remove windows 7 only how will I do it to keep windows 8 only.

    I have a Toshiba laptop with windows 8 pre-installed in it.
    1) Downgrade to Windows 7.
    Downgrade Windows 8 to Windows 7
    Warning you must have the UEFI/BIOS firmware setting in Step Three set.


    2) If Using a USB Pen drive on a PC with a UEFI BIOS.
    USB Pen drive need to be formatted to FAT32 as in
    UEFI Bootable USB Flash Drive - Create in Windows
    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.

    I have a Toshiba laptop with windows 8 pre-installed in it.
    I missed that you had Toshiba, you need to reinstall Windows 8 in Legacy mode, to dual boot Windows 7.

    From Toshiba Support site.

    Thank you for the replay, now I have reached installation till where do you want to install windows?
    I choose installing a fresh copy of windows (custom installation)
    Here it shows windows cannot be installed to Disk 0 Partition 5. (Reason: The selected disk is of the GPT partition style).
    I have shrinked the HDD space to create 25 GB new drive.
