I'm hoping someone can help with this. I have installed Win 2k and Redhat 8.0 and Grub worked fine. Due to a problem compiling C programs my tutor advised me to use Redhat 7.3. I've installed it but it hasn't come up in the Grub Selector so i can't run it. I was hoping someone could tell me how to configure Grub to list all the OS's.
