Assembly 如何从软盘运行简单的操作系统？

我最近一直在尝试在汇编中制作操作系统，但是我遇到了一些问题。我可以在VirtualBox中运行我的操作系统，但它只是告诉我，一旦我尝试从软盘驱动器中运行，就要从软盘驱动器中删除介质。我在多台电脑上都试过，但他们都说相同的。我不知道还能尝试什么，我会把我的源代码放在下面，以防它对你有所帮助。 提前感谢,， 杰克·撒迦利亚·尼克松

再次感谢：）

很难说到底是什么问题，但这里有两件事你可以试试

您正在使用的计算机是否已设置为尝试从软盘驱动器启动？在BIOS设置中验证这一点（在启动过程中按特殊键输入）

磁盘是否可以引导？下面是一个OSDev教程，其中有关于创建软盘引导操作系统的说明；在最底部，它给出了如何创建软盘的说明：

它起作用了！我发现问题在于我没有正确地将图像写入软盘！谢谢你的帮助。如果其他人也有同样的问题，我找到的最好的软件就叫做。它非常容易使用，而且速度非常快。 再次感谢，

对不起！在发布答案后的一段时间内，我才能够做到这一点。然后我就忘了，哈哈：）谢谢你的提醒！
