    Tablet upgrade, retrieve 8.1 key


    Hi,

    I have a cheap Windows table (Irulu 9" Walknbook 16GB) with Windows 8.1.
    In preparation for upgrading to Windows 10 I deleted the large recovery partition and tried to merge the Windows partition, so as to have enough space for the upgrade. After that, it would not boot into Windows.

    I can get into the EFI shell and boot from a Windows 10 USB media, but it can't repair my 8.1.

    Before I fresh install Windows 10, I think I need the 8.1 product key!

    Is it likely to be in the UEFI, if so, am I OK to run the Windows 10 install? There certainly isn't a label on the tablet with the product key.

    If not, how can I best extract it from this tablet that will only boot in EFI and not in legacy BIOS mode?

    Can I add this to the USB drive I'm using, boot into recovery tools and run it from there?

    EDIT:
    I just thought, even if I extract the 8.1 product key or it's in the UEFI anyway, will I be 'allowed' to do a clean install of Windows 10 without having upgraded the 8.1 first?
    That is, in order to get Windows 10, do I need to reinstall Windows 8.1 and qualify for the free upgrade?

    You can access the Command Prompt using a Windows 10 DVD. I just did so today.

    'When you install Windows 10, you can enter your PC’s Windows 7, 8, and 8.1 product key and it should activate properly if that PC was eligible for the upgrade.'── quoted from Whats First Big Update (Which Arrives Today)

    The key will be embedded in bios. You can extract key after 10 is installed, but it should pick it up automatically.

    If I re-install Windows 10 after updating the BIOS, do I have to enter the key again?

    No. Updating the BIOS does not affect the product key that the manufacturer stored there.

    This is theoretically correct but some users have claimed they have done bios upgrades that have gone wrong and managed to lose the bios key. Whether this is true I cannot say, but I would make a note of the key before flashing bios just to be sure.

    I've flashed the BIOS on my laptop twice, no effect on the OEM embedded key. My understanding is its stored in a section that is not overwritten by a BIOS flash. Maybe even in a non writable section. AKA permanent. My MSDN ISO and media from the Media Creation Tool read it and use it. In my case I wish they wouldn't but they do. If I use stock install media I get 10 Home. My OEM key is for 8.0 Core. I got 10 Pro via the free upgrade. It just means using a little trickery to install Pro instead.

    EDIT: Forgot to add, and yes, you can clean install without having to do the upgrade first.
