I think I have mis-understood something here sorry.
Is ShannockSid saying Missing/Corrupt 98se files or Norton files??
ShannockSid, go into bios and change the start up from C:\ to D:\ or whatever your first CD drive is. Then put the 98se disk in, and boot your pc up with it in. Let it re-install 98se. You should NOT lose any data or programs that you have saved. All it is doing, is re-installing some of the missing or corrupt files.
