installing a second Distro will this mess up Grub
 
I installed a second Hard drive and I am wondering what will happen when I install another Linux distro on the new drive. will it screw up grub?

I recommend that you tell the second distribution to not install a bootloader. You can then add the second distribution to your existing /boot/grub/menu.lst file in order to dual boot.

No, tell your second Linux to install its GRUB to its boot or root partition and use chainloading.

add it to menue list with out installing the second grub
UNLESS IT IS Fedora 9
fedora9 uses a 256 bit boot and ubuntu,fedora 8,all other has a 128

well what distro did you install ( Mythbuntu ??) and is the new grub on the first patririon of the first disk ( mbr)
OR is it in the first partition of the new os's partitions .
or did you try to put the new grub on a LVM ( will install but not work)
can you post the output of
---
fdisk -l

I reinstalled Mythbuntu then using this command
Sudo grub
then root (hd0,6)
setup (hd0)
which I thought would put mythbuntu into the opensuse grub ( because that is where grub is on Opensuse) but it didn't
not sure how to add Mythbuntu to grub lol

concerning this issue, I found this link http://www.brunolinux.com/05-Configu...boot_grub.html pretty useful!

well you put mythbuntu in (hd0,6) = /dev/sda6 a swap partition

you needed to but the new os on (hd1,0) = /dev/hdb
and ether but grub in hdb1( first part. of new os) or over wright hda1 ( mbr ) first disk

also you don't need two swap partitions the 2 os's can share one
