Bootloader Implementation

[brodeur235]

I want to make a minimal OS that boots and displays 'hello world.' I understand that I need a bootloader and a kernel. This is my first post and you all don't know me, so let me tell you what I know how to do.... of course html, css, js, php, c++, obj-c, java, as, and the basics of intel and at&t asm. By basics i mean program flow, loo[ing, general memory allocation, general procedures, etc. Back to more specifics, I understand it is the boatloader's job to load the os into memory. The BIOS (I do believe thats the term) on my machine allows me to choose between all available bootable partitions at startup. I want to put my os on a 2 gig usb that I have for easy development alterations without having to burn a disc every time. My question is more technical than anything else... How do I do all this? For instance, what partition type do I use to format the usb? Is there a specific directory path that the bootloader and kernel have to be in on this disc? etc. If I am missing some bigger picture its not surprise to me because I have a tenuous grasp on os development at best, but please help me out if you can. All help is appreciated,

P.S. I do not want to use ANY external libs/code for my first OS. I'd like it to be 100% me for learning purposes.
