    Yeah -- I know that. The OP asked if those DVDs would install, and from my experience, they do not -- even though they should. I tried several different ones, and they all failed the same way.

    They work for me, mine are MSDN ISO's with that one little mod. I used to just use the Windows 7 DVD download tool to create a bootable thumb drive from the stock ISO. Then just go in a delete the ei.cfg file to get the full menu with the list.

    It means it has a factory OEM BIOS SLIC table. Windows 7 factory OEM installs don't use embedded keys in the BIOS. There is just an OEM marker in there. If Windows 7 isn't currently installed, and you didn't do an upgrade install from it, there won't be any key to retrieve. If its there it listed as Original Key by show key. What is listed for Original Edition, if it say Windows 7 then what is listed as Original Key is your Windows 7 key. If that's the factory OEM-SLP key its useless without the matching factory install media.

    I'll assume your wanting to go legal. Can you read the key on the COA sticker? You'll need that and install media to reinstall the original Windows 7. There is this site, but I don't know if you can download with an OEM key? Software Download

    Remove the battery and have a look in there. If you don't have a COA sticker you need to buy the original recovery media or buy a new legal version of Windows.

    Windows7 and Windows10

    Thank you


    I just registered to say thank you. This guide helped me out when reinstalling Windows 8 on an Acer Aspire v5 that refused to boot. It was stuck in a 'repairing' loop.

    To try to correct the problem I created a bootable pen drive on another windows 8.1N laptop. This worked to reinstall Windows 8.1N but the activation key was not picked up by Windows.
    I tried manually entering the key after extracting it from the bios but that did not work either.

    Next I tried to use the factory-reset partition that came pre-installed from Acer. It should be activated by pressing ALT+F10 during boot but that did not work. My guess is that the reinstallation of Windows8.1N had destroyed the original bootloader from Acer that knows how to boot that partition.

    Using a Linux bootmedia I checked the data on the recovery partition and noticed that there was a install.wim image.
    So next I tried to use the guide from this post Restoring OEM Windows 8.1 from "install.wim" file only
    to create a bootable usb drive to reset to the push-button-factory-image. While the stick booted the installation aborted since the stick was reported as being invalid.

    What finaly worked

    I was about to cough up the 80 bucks Acer extorts from customers for a recovery DVD when I stumbled on this thread. I followed the instructions and was able to create a bootable-usb drive that could install Windows 8.1 using the media creation tool. Once I had the correct image (Windows 8.1 NOT Windows 8.1N) it picked up the OEM key during the installation and now everything works. I was even able to start the upgrade to Windows10

    Why windows is so damn picky with what image can be used with which key is beyond me. What is the difference between Windows8.1 and Windows 8.1N anyway...




    Quick follow up question: Since now I have switched to Windows10 and I do not trust the built in recovery functionality I am looking for a decent (free for home use) imaging tool. Any recommendations?
