I think this goes here. "Replace Windows 8" option also erases entire disk
I have HDD which until recently had two partitions: NTFS with legitimate Windows 8 and ext4 with Fedora 20. I decided to install Ubuntu instead of Windows, just to give Ubuntu a try. I took "replace windows 8" option (мy thoughts were: "What a service!") during installation, assuming that only windows 8 will be removed. Imagine my surprise when I discovered that Ubuntu "replaced" entire disk with itself.
