If I'm performing a an upgrade to Windows 8, do I have to have the previous version installed, or is just having the key enough?



I'm planning to buy a Windows 8 Upgrade for my computer, and need to know if I have to keep my Windows 7 disks around and have to install Windows 7 first before doing the upgrade, or if there is somewhere that I can enter my Windows 7 key alongside the Windows 8 Upgrade key if I want to do a clean installation of Windows 8 from bootable media.



Can I get by with just writing both keys on the disk like I have in the past?


Answer



You can install the upgrade without previous OS installed:




You just need to make a Windows 8 Pro upgrade install media and then boot from this disc and install the system (classic windows install procedure). If you get an error when activating (0xc004f061) then call MS support and they will help you to activate the system (you will need previous OS product key and the new Windows 8 PK).



How to create Windows 8 Pro upgrade install media?
Download the Upgrade Assistant from http://windows.microsoft.com/en-US/windows-8/upgrade-product-key-only and then run it on a Windows 7 or Windows Vista computer (Windows XP won't work). In the wizard select "install by creating media". It will download the files and then create and ISO file. Burn this file on DVD and you'r done.
