Hi Robert,
Deleting your backup is probably a little bolder than I would have been, but
nevertheless you still have a booting system and all your data files, so you
are in good shape. :-)
The only problem to solve is to get yourself a bootable copy of Snow Leopard OS
X 10.6. How did you go about installing Snow Leopard on the second partition?
Did you use Carbon Copy Cloner to copy back your original system, or was it a
fresh install from a CD?
