Hi Amy,

Another thing you might try is logging in to "single user mode" and
editing the file you changed from there. When you boot your server you
should have about three seconds when the boot menu comes up to hit "e"
for edit mode (if I remember correctly) then you can use the arrow
keys to naviage to the line which has boot info about your kernel
(usually the second line down). Hit "e" to edit this line and add this
at the end "single" (leave off the qoutes). Then hit enter, that
should return you to the previous screen. Hit "b" to tell the Grub
boot-loader to load. Hopefully the computer will boot into a command
line with you as root.

Here's another description taken from a site I found via google:

"Using GRUB, you can manually edit the proposed menu entry at boot
time. To do so, when GRUB is presenting the menu list (you might need
to press ESC first), follow those instructions:

    * use the arrows to select the boot entry you want to modify.
    * press e to edit the entry
    * use the arrows to go to kernel line
    * press e to edit this entry
    * at the end of the line add the word single
    * press ESC to go back to the parent menu
    * press b to boot this kernel

The kernel should be booting as usual (except for the graphical splash
screen you might be used to), and you will finally get a root prompt

Here's some google keywords to try

fedora grub single user mode

Hope this helps.
