Do you by any chance have a Mac running OSX 10.4 or earlier? By taping over the hole on a 1.44mb disk you should be able to make a fake 800kb disk and put Apple's image on there, then you can try installing that onto your SE's hard disk.

Unfortunately, this does not work. An 800K Mac floppy requires a quite different physical formatting than 1.4MB ones. Newer drives (and this includes all USB external units, and anything that shipped in the OSX era) simply lack the hardware to support 800K disks.

Ah, well if you have access to any old beige Macintosh with a floppy, you could give it a try. I used my vista computer with external usb floppy to move the file to my Color Classic, where I expanded the file and used disk copy. Took me 5 disks (all taped) to make a bootable 800k disks -the rest of them would boot only in Superdrive computers (and read as 800k disks) but wouldn't be recognized or booted by the SEs.
