| 10 | Writing out an MBR is straight forward (it is assumed below that /dev/hda is the target raw device and /dev/hda1 is the target partition): |
|---|
| 11 | |
|---|
| 12 | dd conv=notrunc bs=440 count=1 if=mbr.bin of=/dev/hda |
|---|
| 13 | |

| 14 | Writing a VBR to match Syslinux requires more work as it must have a jump and be offset into the partition (and as a result the code must be compatible with this offset): |
|---|
| 15 | |
|---|
| 16 | echo -en "\0353\0130\0220" |dd conv=notrunc bs=1 count=3 of=/dev/hda1 |
|---|
| 17 | dd conv=notrunc bs=2 count=210 seek=45 if=mbr.bin of=/dev/hda1 |
