i know how to edit the boot.ini, i had to rebuild it because of corruption once. But how would i go about writing my part with my kernel?

Or you could use Cygwin... or use the built in Windows ability to do it... or use a Windows Equivalent (at least for this operation) of dd, like John Fine's partcopy.

I have partcopy put i dont know how to write to the partition i created on same hard drive without destroying my windows

binutils:
I tried using dd and i use the command (F is my empty drive)
dd if=mikeos.flp of=\\.\f:
It gives me an error on output being used.

dd is a unix file utility.

check out this description. it's a dd man file dump.

It can be used to create raw disk images that you can mount in *nix systems.

And thinking about your problem, it seems to me that you are going way out of your way to write an OS. Why do you need to write it to the harddisk to begin with? You are going to be doing a lot of rebooting your machine if you do it that way. So why not go with a virtual machine such as bochs, qemu, virtual box? You need to restart all you have to do is restart the virtual machine.

[EDIT: Sorry, didn't see the second page of posts. Forget this reply]

I have emulators but it sometimes isnt the same feeling. Or am i just wierd???

Oh and another thing, i use Winimage to make my ima files right to boot from Qemu...well i tried throwing all my bins into a ima then booted in qemu and i get an error right after the boot message comes up (default says "Made with Winimage blah blah blah...) well the error says cannot boot from disk or something like that

i thought maybe it had to do with my code but i opened the original floppy image that comes packed with mikeos and it boots but when i extract the bins then repack in a ima file it gets same error

my tip indicated only your f drive is usb and the image is maden for usb drive.
maybe to see the source of dd give you some hint.
