grub rescue means that grub is in emergency mode because it could not 
find its modules. This is definitely not ok :). It usually indicates a 
device path issue.

In your case, I'm slightly puzzled why grub would append ,msdos2 to a 
netboot path. But it definitely looks wrong, as it could not find the 
real config file (which should also reside at the tftp location).
