OK, all i want to do is install Red Hat 9.

But it wont let me....
"You have not defined a root partiton ( / ), which is required for installation of Red Hat Linux to continue. "
WTF does that mean?

How can I use Linux to make a partion drive?
I want to leave drive d my back up drive how it is.
And I want to use drive c for linux. 6gb+

.........

When you started the install you must have said manually configure.

If so you should choose cfdisk and setup your partitions. Part of setting up partitions is to set the mount point.

At a minimum you should have a partition (I recommend at the beginning of the drive) around 100 MB that has the mount point /boot and another partition that can be as big as you want to have for space for the linux system that will be mounted on /

/ = root with respect to partition mounting

so i need to make a /boot and a /what for linux?

Why can't i just make a /boot for linux?

The directory layout (referred to sometimes as the filesystem or filesystem layout) in linux is one of the "tree" style. / is the base directory, from there comes everything else. /home is the home directory, it's located within the / (root) directory at home, so it's shown as /home Same with boot, it's within / so it's shown as /boot and so on. There are quite a few threads that describe this better, and how-tos written as well, I'm just giving you the tip of the ice-burg to help you understand the need for things.

You only NEED a / everything else will be created within that. For now, only create what you NEED, later you can change things.

Cool

Just restart the install and choose Atomatically configure. If you are a newbie, then DON'T manually configure the install - that is bad advice. I assume you just want the OS up and running and don't want to mess with anything!!
