overwrite windows mbr c++

To overwrite the Windows Master Boot Record (MBR) using C++, follow these steps:

1. Include the necessary header files:

#include <fstream>
#include <iostream>

1. Define the MBR size and file path:

#define MBR_SIZE 512
#define MBR_PATH "\\\\.\\PhysicalDrive0"

1. Create a function to write the new MBR data:

void overwriteMBR() {
    char mbrData[MBR_SIZE];
    // Populate mbrData with the new MBR content
    // ...
    std::ofstream mbrFile(MBR_PATH, std::ios::binary);
    mbrFile.write(mbrData, MBR_SIZE);
    mbrFile.close();
}

1. Call the function to overwrite the MBR:

int main() {
    overwriteMBR();
    return 0;
}

These steps illustrate how to use C++ to overwrite the Windows MBR.
