Possible, but what "something"? The new system is an exact copy of the 
original, just on another partition. On a grub-legacy system, there are 
two "something": fstab and menu.lst. If you correct them, the system boots.
If you use grub 2, you can't correct menu.lst, and the system hangs. So 
whatever "something" is, it's grub 2 related, as far as I can say.

Then give people a choice. Most computer users don't have multiple drives that 
can easily change place, and certainly don't have "multiple i/o controlers". 
Swapping an boot system that is easily controled by ordinary people in 
ordinary situations for a new system that only enables control by specialists 
in a special environment is just absurd.
