I have a backup of my cf hd as it stood when i did a clean install of classic workbench 68k. So it has my Whdload key, roms and other bits of software ready. All I simply do is connect my cf card and load it as a hd in winuae, do the format and then copy everything over using my backup of workbench. Just use Opus to transfer everything over. It takes about 20 min with the amiga correct write speeds.
