windows 8 activation after clean install does not accept product key

GeoffWoods asked on

Dear all,

I had a dual boot system with windows 8 and Ubuntu and tried to remove the Ubuntu but the computer did not boot, I was trying to fix the mbr and got it wrong.

I then did a clean install of windows 8 but it will not accept my product key. Before the clean install I formatted the hard disk.

Is there anything I can do or do I need to purchase another windows 8 pro?

 

regards

 

Geoff Woods

Unless you bought the System Builder DVD version of Win 8, you bought an upgrade.

You need to install the OS you upgraded from and then re-upgrade using your Win 8 installer and PK.

You need to buy another Windows 8 Pro from Amazon as you use Ubuntu, which cannot upgrade to Windows. There is an unofficial, possibly illegal way to using an upgrade product key with a clean install, but I don't recommend it. The link is at http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install/windows-8-pro-upgrade-product-key-cant-be-used-to/1726d238-98fb-4634-a468-04645a8ee097.

Steps:

1. Run the registry editor (regedit)
2. Find the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OOBE
3. Change the value for 'MediaBootInstall' from 1 to 0
4. Open an elevated command prompt (run as admin)
5. Run the following command: slmgr -rearm
6. Reboot

Now you can activate.
