I am running a dual boot machine with Windows 7 and Ubuntu 16.04. I want to leave the Windows partition as is, and completely replace Ubuntu with Fedora Workstation 25. I have created a USB to boot Fedora from and started working through the "install to hard drive process". That part is all fine.
I am a bit lost when I get to the part where I am meant to select the mounts for the partition. There are lots of different schemes and so on, and one which says something like "automatically select partitioning scheme", but I'm worried this will delete part of the Windows partition to make space, or leave Ubuntu on there, or something.
What is the simplest way for me to replace Ubuntu with Fedora, while leaving Windows untouched? I am a complete non-expert, and don't understand enough to follow the online tutorials I have seem (which tend to assume you have Windows installed and want to add a second OS, rather than replace the second OS with a third one).
