Understanding what the error message is saying would be the first step.

Grub documentation tells me that you are most likely getting an error
message such as the following.

Online grub documentation
http://www.gnu.org/software/grub/manual/html_node/index.html

Error 15: File not found
Press any key to continue...

>From the Documentation
15 : File not found
    This error is returned if the specified file name cannot be found,
but everything else (like the disk/partition info) is OK. 

i.e. one of the files refered to in the grub boot command cannot be
found. Usually the kernel image.

So, the error message suggests that grub is installed fine, but one of
the files needed to boot linux cannot be found.

Next, at the grub command line (after it boots to the grub menu, press
c)
type
find <kernel_image>

where you substitute <kernel_image> with the kernel file name that grub
is looking for, and see what device it reports it as being on.

This should help you establish if file it is looking for is on the
device that is refered to in the /boot/grub/grub.conf (also called
menu.lst) file.

Depending on what it is, it should just be a cause of correcting the
file name or device name used in the config file.
