I know I am tired and have just done something stupid, but I am still going to ask for help.

I just finished my Gentoo install on my Dell PowerEdge 1800 and I see the following message when I try to boot up:

Booting 'Gentoo Linux 2.6.12'

root (hd0,4)
Filesystem type is ext2fs, partition type 0x83
kernel /kernel-2.6.12-gentoo-r10 root=/dev/sda5

Error 15: File not found

Press any key to continue...


Here is what I have setup for partitions:

sda1 is a dell diag utility
sda2 is boot
sda3 is swap
sda5 is /
sda6 is /var
sda7 is /users


I think I just setup something wrong when I configured Grub....but I need some assitance on how to easily get back and reconfigure it...assuming I can figure out what I did wrong. I guess I can just follow all of the install instructions in the gentoo handbook and get everything mounted and chrooted into my environment, then try to reconfigure grub....am I even close to on the right track here?!?!

Look at the Gentoo Grub Error Collection in the Grub Error 15 section.

Hi.

You can use the live-cd to boot and correct GRUB or you can use te GRUB command prompt. By the way GRUB error 15 usually means that there is no kernel or initrd file with that name in /boot.
The first method should be done as you describe it. The second method requires you to press 'c' when GRUB shows the menu and to enter the details on the command line taking advantage of its auto-completion feature:
Code:
grub> root (hd0,4)
grub> kernel /kernel-2.6.12-gentoo-r10 root=/dev/sda5
grub> boot

You should start writing the kernel line as kernel / and then press the TAB key. GRUB will show you the list of files under the /boot dir. Select the proper kernel and complete the line. Then issue the last command and GRUB should boot into your new system. Don't forget to update grub.conf after booting into your system, so that you can reboot into your system again.
