How do I read and write to the boot sector of a floppy or hard disk in NT using Visual C++. &nbsp;I've been reading docs on the internet and I think I need to use the CreateFile and DeviceIoControl functions, but all the examples on the internet only explain how to read and write to a file on the disk. &nbsp;I would like to read and write to the boot sector of these disks.<br />

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
