Hi!
Just write those two files and see what happens.
Maybe one of those files already contains a bootsector,
and will boot when it's required.
EDIT0:
Hey, maybe one of those files is a malware,
it would be cool if it alters cpu voltage settings,
during a boot,
at set's it to 100.0 V, so, you get a speed boost,
up to 50 Ghz, at least for a milisecond. :D
Well at least it will shutdown very fast with
sparking screensaver effect and zzzZZap sound. :D

No, it doesn't make a difference.
I have changed my boot up to floppy and then CD then hard drive.
Well, then your boot files doesn't work.
Try other files.

Without knowing what these two files contain or what architecture the floppies will be booted under, I'm not sure if we can help you much. If you want to try and figure it all out on your own but just need to know how to write binary data to a floppy then it's no trouble. There are three programs commonly used for writing an image to floppy disk; MS-DOS debug (http://technet.microsoft.com/en-us/library/cc722863.aspx), rawrite (http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/disk/rawrite/) and dd (http://pubs.opengroup.org/onlinepubs/9699919799/utilities/dd.html). If we were to ASSume that your bootloader was named `boot.bin` we could insert a formatted floppy disk into the computer and write the file to the bootsector using one of the following commands.
C:\>DEBUG boot.bin
- w 100 0 0 1
- q
# dd if=boot.bin bs=512 of=/dev/fd0
C:\>rawrite
RaWrite 1.2 - Write disk file to raw floppy diskette
Enter source file name: boot.bin
Enter destination drive: A:
Please insert a formatted diskette into drive A: and press -ENTER- :
Number of sectors per track for this disk is 18
Writing image to drive A:. Press ^C to abort.
Track: 16 Head: 1 Sector: 16
Done.
I'm certain this doesn't answer your question, but I hope it does point you in the right direction.
Best of Luck,

Oh well, guess you found your solution after all. :D
I'll still post the above in case it helps.

You got a floppy drive? Cool! That's rare these days, I think.
You mention two files. What's the "other" one? Two different bootsectors or a bootsector and a "second stage" or kernel? Well, doesn't matter if you've got it working, but yeah this is a good place to post the question...
Best,
Frank

Ya thanks everyone it was a issue with my external floppy drive, it had some thing plastic in it, it was not the boot loader or kernel files it was my floppy drive. sorry about that.

Installer said "insert disk three" but only two would fit... :)
