Hi guys, Tolerance here, new to the forums as some of you may notice. Anyways I'm trying to install Windows 7 ultimate package on a PC that previously had Windows Vista. I've already ran the Windows Adviser program, and my PC seems fine so i went ahead and tried to install. First i tried using a burned ISO file to a DVD, with this i made my primary boot device the DVD drive, and my setup started normally. But after i selected the language, then a custom installation, and was directed to select the driver in which Windows 7 would be installed on i would get an error that reads, "No device drivers were found. Make sure the installation media contains the correct drivers then click OK." I've browsed these forums looking for someone with similar problems, and i did find them, and a lot of the threads were really annoying seeing as how so many people decided to reply with long irrelevant comments. Based on the answers from those threads I've tried burning the ISO file with a different burner (which was suggested often), but still with no prevail. So i was wondering if there was a problem with my system, or maybe my C: drive. If any additional information about my CPU is needed please tell me and i'll do what i can to help.
