I recently had to reinstall an OS on the wife’s Dell Inspiron 17. I was unable to complete an install for Fedora 22, but Fedora 21 and Fedora 23 beta were able to install. It would always freeze mid-install – usually around 70 or 80%. From what I could gleam on the net, it has to do with a kernel issue. But I’m not 100% sure. Anyway, just putting this out there for anyone trying to get Fedora 22 on a Dell Inspiron 17.
