I don't know what the installer did, I will need to examine the results. I just let the installer have the entire disk and let it do its thing. I'll take a look and see what happened later and let you know.
Somebody else who also has a Windows 8 laptop approached me yesterday to see if I can install Ubuntu for him, - my boss! So I have the two most important people in my life wanting me to install Ubuntu for them. I can't afford for anything to go wrong or my life could be made miserable for some time.
Having the revomed the entire Windows 8 and having it completely out of the equation makes everything a lot simpler. It's worth a hundred bucks for a new hard disk the peace of mind of knowing they can just switch hard disks again if they ever want to.
