How can i put a compiled boot sector onto a USB stick or disk?
I'm actually interested in how an OS works, from the POST over the Boot process to the Kernel, GUI, etc.
Well I have to start at the beginning: The bootsector
Most tutorials only specify how to get your .bin bootstrapper onto an USB stick for Linux users.
But as I'm using XP I would like to ask how do I get my 512 byte .bin onto the right position on my USB , and thats definitely not by copying it with explorer :D
There's dd for Windows which I use regularly. http://www.chrysocome.net/dd
use it like so:
dd if=c:my filesboot.bin of=.z: bs=512 count=1
where 'z:' is the drive letter of your mounted USB drive, 'if' is the input file, and 'of' is the output device, bs is the block size, and the count is the number of blocks to copy
I do this about once a month to see how Haiku development progresses. They offer raw disk images that are written to a USB drive this way.
WARNING: Getting the drive letter wrong can destroy YOUR bootsector, so make sure you do a backup and become comfortable using dd first. I've lost a lot of data to it's power.
Maybe you could use rawritewin to do the job for you?
The other way is to use UNetBootIn but from my experience in messing with it, it requires an ISO to be burned onto a USB.. so that may not work in your case but you could try creating an ISO in preparation to be written to the USB...
