Microsoft have updated the downloader so that it requires no product key and gives a Windows 8.1 with update 1 that accepts Windows 8.0 and 8.1 product keys for installation both retail and OEM. It now allows selection of architecture, language and version. See here for details: [URL] The downloader requires a Windows OS to launch, its a .exe so its best to use a Windows based computer. If not you need to download Windows 7 and install without a product key in VirtualBox/VMWare Player then use that to download Windows 8.1. Its easier to just use another computer.

Hello everyone! I've got a problem with my Dell. I tried to install an Ubuntu Linux on my laptop and the installer accidentally erased my preinstalled Windows 8 with all my data and so on. Is there any way to download an original Windows 8 iso to burn it on a CD or a bootable USB and install Windows 8? I tried by downloading the Microsoft's tool but I need my serial key, which is hidden somewhere in my UEFI/BIOS. Maybe Dell can send me some iso or link to download it? Someone had a similar problem?  Thank you, Piotr.
