<< I've noticed some of you put your OS on the first partition, and, the applications on the second, and, data on the third......,IF the system crashes, and, you reinstall the OS on the first partition, will the applications still need to be reinstalled? Assuming the OS is Windows 95/98, or ME. >>
For the most part, yes you will have to reinstall the programs. This is true because most programs either write to the registry or install .dll files into the windows system itself. When you lose windows, you also lose all those .dll files. If you try open a program it will most likely say something along the lines of: "Missing *.dll"
