I’ve never installed fedora specifically but…
Anyway I created a free 900GB ext4 partition
It’s either ext4 or free, can’t be both. Now, if it was ext4, Fedora would for sure detect it as such, so I’m not sure what it is.
I assume you would want to click on sda6 in the installer, then the “-” button to delete whatever is there, and then it would recognize it as available space.
I never really figured this game out, and the only thing I really remember is that while playing I was listening to a video about the “trying to trademark reaction youtube” debacle.
Anyway. Bye.
