http://forums.fedoraforum.org – Hey guys, Yesterday i helped my cousin install Fedora 17 on his laptop. We created a separate partition for fedora, so he could dual boot with win 7. We installed 15 first, and were going to use preupgrade to upgrade to F17, however, he decided to stick with f15. So I told him to update through terminal, and here's where we ran into a problem.
