I can't get windows 95 to start. While it is starting it gives "invalid system disk" If I put in the floppy startup disk it will say "starting windows 95" and then go to the a: prompt. I can't get to the hard drive. I tried safe mode but it didn't work. This all started when I was trying to install a new cd burner. It would start part way and then give errors about the config.sys file. Now I just want to get back to the original state.
