title: How to transfer the control from my boot loader to the application located in hard drive
body: <p>I am using NASM on Windows and testing it on VMware, and successfully made my boot loader. Now I want that my boot loader transfers the control to some application (say I want to simulate the work of kernel), but instead of kernel I want to load some app? Can you give me some hint how to locate the file in HDD in terms of sector, head etc and then load into ram?</p>
  <p>I know that kernel is located at address 2000h also an interrupt 13h which loads the harddisk information into RAM, but how to find the exact sector, head for that file?</p>
