but installation in MBR or PBR does not need filesystem

have I misunderstood the functioning of setup in Grub legacy:

It checks the availability of the files in the filesystem and
copies the necessary stuff (including the block "pointers") to
MBR or PBR. In this case it needs only read access to the file
system. 

Otherwise: please give me some tutorial, what it does.
