Q: Mac Classic Not Booting?

Ok, so, I have a Mac Classic. The 2MB model with the 40MB SCSI HD. Whenever I do Command + Option + X + O I get the error screen ID = 02 "A System Error Occured" What is this error and how can I fix it to make the Mac boot directly to Mac OS?

P.S. The Floppy drive works, I am temporarily using a floppy bootable Mac OS
