How to Clean Install with Windows 8 Upgrade

post #1 of 3
Thread Starter 
It appears that quite a number of you recently purchased an upgrade copy of Windows 8. If you tried to install it on top of your existing Windows 7 OS, it will install fine. However, I know that many of you wish to perform a clean install, since this forum is dedicated to "the pursuit of performance" after all. So mods, before you contemplate on editing out another one of my posts for possible TOS infringements, understand that this thread is only meant for those who were able to obtain a copy of Windows 8 Upgrade in a legal non-loophole way, and that they do have an existing copy of Windows 7 prior to the purchase. With that said, here are the steps:

1) Install Windows 8 on a new partition, thus wiping out everything on the hard drive, including Windows 7. During installation you will be prompted to enter your serial key.
2) Upon successful installation, you should be able to get into the new OS without any problems. However, if you open up the Activation window (can be found through "search" or control panel.. I know it's hard to navigate the new OS), it will say that the key has not been activated. You can try inserting the same key you put during installation, but it will give you an error and won't activate.
3) Open regedit by pressing Windows+Q and typing "regedit" in the search bar.
4) Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/
5) Change MediaBootInstall from 1 to 0
6) Close regedit
7) Open command prompt by searching for "cmd". Right click on it and select "Run as Administrator"
8) Type "slmgr /rearm" on the command line (without quotes) and hit enter
9) Reboot your computer
10) Check to see if your key has been activated, if not click activate and it should work.
