Ok. I have a dell lattitude e6220 and it was running windows7 ultimate but was haveing log in issues. So I tried  every windows install disk I have formated both sections as I do with any other computer ive worked on, and I keep getting the same result wich is,                                                       "windows setup could not configure windows to run on this computers hardware.  But then I go to install windows 8 pro and it goes through.? Very odd Ithink. Im ok with haveing windows 8 on Iit but the only issue is theres no wifi drivers? I think I found the drivers I need but its not compatable with windows 8? Any help would be much appreciated thank you.
