    Most Laptops come with 8.1 (core) and not 8.1 Pro so you have to download the same version. The ISO from the Media Creation Tool will use any 8 or 8.1 key and read it from the Bios if it is OEM.

    I m not sure what version was installed. I downloaded d tried win 8.1 core. It didn't succeed. Then I m downloading single language one now after I spoke to the customer care of Microsoft and they came on remote support accessed PC d tried activating licence. Prob s it doesn't read from bios. They asked me to download 8.1 single language now to refresh the system with it. Have a v poor broadband speed .

    Summary - key not reading from bios. Have key noted d kept d confirmed by Microsoft its genuine d can be activated but needs proper os.

    It's actually very simple mate. All you have to do is to check the system information summary and find the installed SKU version.

    System Information - View About your Windows 8 PC

    But if you already wiped the original OS and installed "Core" instead, it will be difficult to identify the edition.

    If you download and install the correct version using "Media Creation Tool", you will be able to clean install for 100 % sure. I have did that dozens of time.

    s told already key in bios s gone.
    Embedded key in BIOS won't simply go away. It's not something a software can wipe but a part of UEFI firmware itself. "Nirosft Product Key" tool will be able to read BIOS OEM key if it is present.

    All other editions can be clean installed by following the below steps.

    1. Use "Media Creation Tool" to download and create install media matching to the SKU version installed on your PC. The ISO/USB reated with this tool will contain "Update 3" and can be used to clean install both OEM and retail versions.

    2. Boot from the USB and it will auto detect the BIOS embedded 8.1 key if there is one. Simply continue the install as normally and activate when done.

    Hi, thank you so much!! This was extremely helpful.

    However after successfully performing a clean install I'm seeing the following message (which I was encountering when I was initially trying to perform a clean install on my own):

    Click image for larger version

    Now I have yet to install any drivers so not sure doing so will take care of things. It does only stay on this error for about 2 to 3 seconds and boots to windows setup after.

    Any thoughts?

    Just figured it out. I had to change the boot sequence to boot from UEFI as it was set to Legacy to load the ISO from my flash drive.
