As I read Eileen's post, installation has failed because the swap partition can't be enabled.
Eileen. Try booting from cd 1 of the installation cds. You should see a menu of choices: install, boot from hard drive, boot from cd. If you don't see such a menu, start installation again.
If you get the menu, choose boot from cd (that boots the copy of the kernel image on the cd; you have a running Linux in RAM to try to fix things).
Once running, open a console window and run cfdisk. It will show you all the partitions you currently have made. Use the arrow keys to select the swap partition; press enter.
Across the bottom of the screen, you have options of what to do with the selected parttion. Use the arrow keys to select Type; press enter. That will take you through a sequence of steps to prepare the swap partition (including one to set the partition type to 82 (Linux swap)).
When that's done, select Write to write the changes, then Quit to quit cfdisk.
Shutdown, then try the installation again.
