I wish. It's machine code. Originally from the DC comic series "52," copies of which can be found in the Mens Interest section under 'pipe-fetishism'. Machine code is code executed by your CPU, and is produced by a compiler or assembler. Once the code is written, you can compiler/assemble it with an compiler/assembler (like NASM for example), but I guess that's just fucking obvious. There are several different kinds of assemblers, each of which suck horribly in their own special way. MASM, for example, uses macros like if and else, so you might as well be writing in C, rendering MASM a useless, nonsensical piece of shit.

or be a wuss and do it in qemu etc, or alternatively brick your computer through love(and a one click installer).

Let's not kid ourselves, you're not skilled enough to overwrite your MBR. Here's something easier. Copy this to a blank text file, rename it to gibson.bat, and run it (pre-Vista Windows only).
