Yes this is possible. For the first task you can use the parttool
command, like "parttool (hd0,1) boot+". Though you should understand
that this just sets a flag in the partition table, nothing more. For
the second task I would recommend making the kernel that you are
trying to load multiboot compliant and loading it with the "multiboot"
