You can't clone a partition with cp, only files. Better to use something like 
"rsync -av --exclude 'lost+found'", and still you wouldn't have a partition 
clone, but only a complete filesystem copy, which _is_ the kind of clone you 
want for this purpose, as long as it isn't performed using a currently booted 
OS as source. Also there is software specifically made for cloning like you 
need. I do all my cloning with DFSee, which isn't free, but is multi-platform 
executable, and compatible, meaning among other things I can run it any time 
I want without a reboot first.

The part of Grub that initiates boot isn't in the filesystem though. Grub's 
files will get copied, but it still needs to be installed to the clone if it 
is to be used by the clone for booting.
