Start by making a simple bootsector that writes "MyOS 0.1" or something, after that simply load a couple of secors after the bootsector (don't care about the filsesystem yet), and maybe enter pmode in the bootsector aswell.
Good tutorials for this can be found at:

When you have the kernel loaded, start out by writing a couple of screen functions to scroll, print and move cursor.
That should keep you busy for a while..
