CentOS - Aug 2007 - HELP, I accidentally initialized my /boot partition

So I installed a second drive in my system today, and instead of  
typing "mkfs.ext3 /dev/sda1" I did a "mkfs.ext3 /dev/hda1".
Fortunately, that was just my /boot partition.  I thought I could  
just copy the contents from the /boot partition from another system,  
but that didn't work as expected.  The again, I don't have another  
system that's identical to the mine.

What is the best way to re-create the /boot partition for my system?

grub.conf will be the main problem...  and possibly whats in the initrd 
if extra drivers need to be loaded to complete the boot (I believe this 
is built by mkinitrd)

Just re-install the current kernel and grub with an rpm -Uvh --force.

initrd images are auto-generated and grub should probe your disk layout
and put some best-guess entries in there.

Just edit menu.lst and fix the entries.
