yeah i tried all the different ways to install like no probe etc. never really thought about media but i do have a pressed copy of freora 5 and it too crashes. not sure what md5sum is? it asks if i wanna run a media check when it installes and i usually click skip i will try to say yes and see what happens.
as far as how it crashes it seems to be random. sometimes it gets to installation progress screen and sometimes it dosent make it that far.
im starting to think its either some piece of hardware in my laptop that fedora dosent like or my dvd rom for my laptop is starting to go bad?
