    [Q] Installing Win7 on Win8.1 Laptop as Dual Boot


    Good day to all,
    I'm just wondering if it's possible to install Windows 7 x64 on my laptop as a dual boot option? It's running Windows 8.1 upgraded from Windows 8.
    If it's possible(considering I'll be installing via partitioning my D drive), will I still be able to use applications installed on Win 8.1 on the newly installed Win7? (ie Microsoft Office '10; various Online Games)
    [edit] And will I have to reinstall drivers? (ie Sound/Graphic Drivers)
    [edit2]
    Specs:
    Asus K46CA

    Intel i3-3217 1.8ghz
    4GB Ram
    500GB HDD
    Intel HM76 Express Chipset
    Intel HD 4000 Graphics
    Windows 8.1 Single Language
    Thanks in advanced!

    Win 7, VM Win 8


    Not knowing the model notebook you have or the age of it, it is hard to say. Although I have Win 8 running in a VM on my Win 7 desktop system I rarely use it and do not have any system designed specifically for Win 8. From what I have read Some feature in Win 8 Locks the EFI ( BIOS ) so no other operating system can be installed. But IIRC that is a Feature of the UEFI and can be turned off.
    So if there are Windows 7 drivers for the hardware in your Notebook you should be able to install Win 7 without a problem once, or IF, that Lock feature is turned off.

    As to the programs you have installed in Win 8, No you can't use them in Windows 7 until you Install them in to the Windows 7 install you plan on doing. You will have 2 separate operating system installed and for each every program you want to use in both will need to be installed into both.

    I see. I'll look into the Locking Feature present in Windows 8 as well. Already added specs and it's 10months old.

    YES & NO, down to your UEFI/BIOS firmware setting.

    As this a OEM manufacturer's PC with Pre-installed Windows 8.

    1) Downgrade to Windows 7.
    Downgrade Windows 8 to Windows 7
    Warning you must have the UEFI/BIOS firmware setting in Step Three set.

    Make sure you read the NOTE at Step three.

    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.


    You will need to buy Windows 7.
