When you say "then it said bash#" i'm assuming you mean your at a command prompt, which is normal. Next you need to partition/resize your disks, in which case you can follow these steps(which is on the link above):
At the prompt, type parted /dev/hdX or parted /dev/sdX (for whichever drive you want to repartition), where X is the partition number of that hard drive.
View the current partition table using the print command to determine the minor number of the partition to remove as well as the start and end points for the partition:
The used space of the partition to resize must not be larger than the new size.
Any changes that you make with parted take place immediately.
To resize the partition, use the resize command followed by the minor number for the partition, the starting place in megabytes, and the end place in megabytes. For example:
resize 3 1024 2048
After resizing the partition, use the print command to confirm that the partition has been resized correctly, is the correct partition type, and is the correct file system type.
Once you have completed your repartitioning tasks, type exit to shutdown your system.
Finally, reboot your system. Rebooting may occur automatically, but if it does not, manually reboot your system.
You are now ready to install Red Hat Linux.
*EDIT* If all this sounds to involved for you, I would suggest installing a newer distro like SuSE which does all this for you upon installation. Here you can find free downloads of newer distros:
