I have Win98SE and I want to know if the following steps are enough to guarantee a factory fresh install: 1. use floppy disk (Win98SE boot disk) to delete primary partition and re-create primary partition 2. format HD and re-install software 3. tap F1 repeatedly while it is booting to get setup menu, press F5 to change to default, press F10 to save and exit I did all of these things and I had error messages that I've never had before after formatting my HD and re-installing my software. I had installed WinME over Win98SE before that and I also took out a sound card which I tried to install. I had a modem which I replaced. Even when I put back the modem, I had error messages for my Ethernet adapter (error 59 I think). Also, I'm able to run UT 2004 demo but not UT 1999. I have the impression maybe some information from a previous installation was still in the computer. How do you make sure you don't have any information left from a previous installation before re-installing your software?
