    You can't download from Microsoft's page, if you have Windows 8.1 OEM product key.

    1) Download Windows 8.1 64-bit ISO image.

    Windows 8.1 with Update (multiple editions) (x64) - DVD (English)
    Release Date: 4/2/2014
    File Name: en_windows_8.1_with_update_x64_dvd_4065090.iso
    File Size: 3924 MB
    SHA1: 4652DC6EBFEBE02C6A63E167C36E3FAEDFB93999

    2) Install Windows 8.1

    You have an OEM computer with UEFI firmware (BIOS) embedded Windows 8.1 product key. The Windows 8.1 installer (when you install Windows 8.1 from DVD/USB) will detect the product key from UEFI firmware (BIOS) and activate Windows 8.1 automatically.

    Thanks I'll have a search tonight
    It's a pain not having recovery disks. My SSD died on Saturday (going back for warranty replacement)
    Other Windows 8 images ask for product key, hopefully 8.1 works as Acer informed me it should be in bios

    My laptop came with 8.0 Core. If I do the install with my 8.0 TechNet ISO it reads and uses the embedded OEM BIOS key. If I use my 8.1 ISO it ignores the BIOS key and prompts me to enter one. It likely works the other way too. If your key is an 8.1 key an 8.0 ISO may not except it. The other thing that can mess you up is if the original factory install was a "Single Language" version. If it is, you need a Single language ISO to use the OEM key. That's what I've been reading anyway. I haven't run into that issue myself, not yet anyway. I don't use my embedded keys anymore any way. I'm running 8.1 on all my PC's using my TechNet keys. The Single Language ISO's can be hard to find. They aren't listed for me on TechNet or MSDN. Not at my subscription level anyway.

    You'll have to search for it on the Internet and find a download on your own. We are not allowed to post a link to unofficial download sites. The mods would edit them out if we did. Google search the file name en_windows_8.1_with_update_x64_dvd_4065090.iso and you should find what your looking for. Once its downloaded compare its hash code to what's posted above. The SHA1 code.
