I am sorry, you are never going to get it to boot on a pc formated disk. When you extract the os to the disk the mpc just can see it as bootable. The disk lable and something else gets harrassed by windows each time the disk is inserted, and overwritten. There are ways that can be avoided and upgrading or installing the latest version of iomega ziptools will solve that as will mpc editor.
With that said, i offer a few suggestions. First get your good new boot disk and for the person without a floppy cable, order one for a few dollars and wait for it. Once you got it, I have had 4 floppy drives fail but for some reason this works on all of them. if you put your finger under the floppy while its inserted and lift a little, enough to hear some noise when its reading its has been enough for me anyways, to get the disk to be read by the mpc and boot. Once booted I get my zip disks, I format like 7 of them, then I load the OS from teh floppy again, and you have to play with it, but it works eventually... and once its loaded in teh copy os screen make a boatload of zip boot disks. You only need to load the os in the copy os screen just once to make as many zip disks as you need.
Now from this point on do not put any of these disks in the windows machine until you have installed iomega zip tools or mpc editor v3 and installed the thing it has in it to prevent the thing that windows over rights and corrupts the zip disk (no vol hack or something like that)
Once you have all that set though you can use the pc to transfer files.
