You both have valid points, but let's face it, if Spike715 wanted to uninstall Windows 8 bad enough he would already have the new operating system to replace it with, before he used my little trick. And if you're going to install a new operating system, you certainly don't want any of the old one left on your hard drive. So, yes I know it's a hard drive wipe, but it gets your hard drive ready for your new operating system.
If you're going to do something, do it right. Have all your tools ready, before you start. That includes the new operating system, and a good driver program. I use Advanced Driver Updater, and have had great success with it. But, that's me, you can look on line for other similar programs.
When you have all your tools ready, run Active@ KillDisk, let it run over night, as it takes a while to complete. Then in the morning, you can install your new operating system, and driver updater. By lunch time you should have a fully functioning computer that you can begin to load your software, and applications on.
Yes, this is a drastic procedure, but I have read so many story's form people who can't seem to uninstall Windows 8, I thought I would offer the Nuclear Option. Windows 8, & 8.1 are fine operating systems for some situations. However, if you've tried, and tried to learn it, and just want to roll back the clock to Window 7, or Linux, you have that right. It's your computer after all.

Mr. Windows
