After doing the above, I suggest you make a grub rescue cd
because I suspect your other disk is the master and you might clear the 
first primary partition of that disk, also the mbr, making all your OS 
unbootable. Then this rescue cd will be very useful. This only works for 
grub2, not grub-legacy.

To make this rescue cd, at terminal...
grub-mkrescue --output=anyname.iso

for karmic and earlier..
grub-mkrescue anyname.iso
