Dual boot is booting from a choice of exactly two operating systems from the 
same partition. Multi boot is booting any number of operating systems greater 
than one from any number of separate partitions.

Next time use the operating system's own shrinking tool. The results from 
Vista's built in resizer are generally exactly what you need.

> It would NOT let me grow the extended partition???

Maybe because it would have killed the existing install on sda5, which would 
have become sda6 if a new logical had been created in between. Such a process 
is better left to experts.

Copying files has no effect WRT what needed to be done. It's the old one that 
was and remains configured.

> How do I change grub to work?

Assuming the files were indeed correctly and completely copied, Grub either 
needs to be installed to sda4, or if already installed to the MBR, 
reconfigured to use sda4 instead of sda5 for its files and config home. You 
could do that either by booting sda5 or booting the CD, chrooting to sda4 (if 
it's workable), update Grub's config to point to sda4 (hd0,3) instead of sda5 
(hd0,4), then running update-grub to actually install it to sda4.

Menu.lst is used by Grub Legacy (1). Grub 2 uses grub.cfg. Thus, your 
installed Grub is Grub 1.
