This may be a grub problem instad of a kernel issue.  If you were able 
to do the install, then this is likely.

Boot into resue mode.  Just answer all questions to the default.
At the prompt you will see some text about where your filesystems are 
mounted. (/mnt/sysimage)
at the prompt:

# chroot /mnt/sysimage
# df -h

You need to verify where / and /boot are mounted.  I am ASSUMING 
/dev/sda.  It might be different on your system.

# grub-install --no-floppy --recheck /dev/sda
# exit
# exit

Remove the boot media and boot normally.

Good Luck.
