Here’s the article I just used to replace Windows 8 with Windows 7:

How to uninstall Windows 8, install Windows 7 on Your PC

Some notes, your Bios changes will probably be different, I had to go into the advances settings and change my boot up mode from UEFI to CMS because there was no legacy setting, this seemed to work. Also, the Windows 7 compatability tool didn’t find all the drivers I needed for installation, however when I went to Driverpack’s webpage and installed the free version of driverpack, all the drivers for the new OS came up and installed fine, except for some keyboard drivers from Microsoft that hung on installation, but I didn’t really need them.
