I have a HP with Windows 7 installed. I want to do a clean installation of Windows 8 from a bootable DVD.
I purchased my Windows 8 32-bit core from the Microsoft store and I received my product key. I then burned the .ISO file to a blank DVD using imgburn. When I restart and change my BIOS to boot from internal CD/DVD and then boot from my internal DVD, I start the installation process.
After I pass the screen where I select the language and location, and click Install it stays there for a minute and then it says:
The product key entered does not match any of the Windows image
I did my research and learned that I need to add a PID.txt file to my source file containing the Windows 8 .ISO but the thing is: I do not know how to add files to the .ISO. The guide I researched is for a bootable USB and I am using a DVD.
