I will like to know, where can I find tutorials in programming an operating system from scratch, (from bootloader -> software).

I understand how the operating system functions and I've written bootloaders for floppies but I need a concise programming tutorials for bootloaders in hard-disk.

Any tutorials/open-source codes will be appreciated.

    There are two books written by Tanenbaum called Operating Systems (Book A and Book B)
    the first book is more on the theoretical side and the second on the actual creation of
    operating systems.
    Also check out
    but this one will be on the linux side of creating your os....
    this one looks promising

    Hope these help....

    Also if you get mixed up with assembly language i'd recommend the book
    Norton has written...
