I am still confused after an hour searching what is the difference and when someone would need just boot ISO or binary DVD ISO Can someone explain in a simple way the difference between them. The only visible difference is the size and the checksum, but this is obvious :)
Used to install the operating system from another source (such as a http repository of the binary files). Can also be used to enter Rescue Mode.
The discs required to install and use Red Hat Enterprise Linux. Can also be used to enter Rescue Mode.
