I created a FAT floppy image with the following linux commands:

dd if=/dev/zero of=floppy.img bs=512 count=2880
sudo losetup /dev/loop0 floppy.img
sudo mkdosfs /dev/loop0

I have created my own bootloader. How can I copy my bootloader to the first 512 bytes of the floppy image.

Thanks!

dd if=bootloader.bin of=floppy.img bs=512 count=1 conv=notrunc

Should do the trick.

I sure hope you have a BPB stored in your bootloader, otherwise you'll lose the FAT formatting
