You said you did some partitioning - what precisely did you do? If you e.g. splitted, deleted or created a partition before your Linux partition, the numbering of the partitions has changed.

In your case (hd0,msdos7)/boot/grub seems to be missing all the grub specific files except a splash image. Normally it should include a variety of files, esp. the modules that are to be loaded (e.g. normal.mod). Did you accidentally delete these files? Or maybe you have a dedicated boot partition, in which case you should find this one and set prefix to it (without the /boot/grub at the end).
