HELP!!

OK, so I set up Windows XP Pro, so you would have to put in a floppy to boot. I forgot how I did it, I was just looking thru files and found this option. OK, so, I did it yesterday afternoon, and left my cpu on all night, cuz I do sometimes. So, today, my cpu froze, and I restarted and it sed "This computer is set up to require a boot disk during startup." So, I knew that, so I inserted the floppy disk XP had written onto, I AM SURe it is the right one, and it said "The Boot Key was not found on this disk, please insert the correct one. So now I can't start windows! I am running off a Knoppix CD now, and, i looked on the floppy disk, and there are 8 files: 6 crptic ones, and one titled: "bootkey.key" and another titled "userpswd.pwd" or something very close to that. And, get this, it says the floppy has 11.3 Gb of data on it! so, can anyone help me, because I have very important settings and files on the cpu. Thanks!
