Yes, there is.
Here you can download executable files to run in Window$ in order to create bootable floppies for the Classic. I myself jammed my Macintosh Classic harddisk boot, and that solved the problem. Hope you will too.
You must download 608sysst.exe. This will create a system disk that will boot the Macintosh Classic with system 6.0.8.
As for the single floppy images for System 7.0.1, you can download them from here.
Feel free to ask if in doubt. Regards.
