grub and old kernel still left behind - multiboot

[Jim Cornette]

After upgrading to FC4T1 on a system with multi-installations, I was 
left with the previous kernel and also grub did not seem to change 
anything related to the grub loader.
Grub was originally using /dev/hdb1 for this  prior installation and was 
left intact when I upgraded via the FC4T1 disks.
Anyway, I am curious as to whether grub works at all from the 
installation CDs. I tried to install a clean system and afterward could 
not access this clean install on another computer. Resorting to the 
rescue CD, the actins seemed to complete, but nothing seemed to take.
