问题

超级用户读者09stephenb想知道是否有可能将他的硬盘分成4个以上的主分区：

Is there a way to split a hard-drive into more than 4 primary partiti***? I am installing multiple operating systems and it would make life a lot easier if there was a way to do this. My hard drive is 1 TB in size.

有没有办法将09stephenb的1tb硬盘分割成4个以上的主分区？如果是这样的话，那么分区的数量到底能“走”多远？

答案

超级用户贡献者gronostaj和danielb为我们提供了答案。首先，gronostaj：

You can use a GUID partition table instead of an MBR partition table. GPT can handle 128 partiti*** by default, but you can increase that number by resizing the partition table size, as stated in this article posted in the comments by @Vality.

Note that GPT is relatively new, and older OSes may be unable to handle it correctly. In some cases, your GPT can be completely destroyed if software does not support it.

A grub menu booting 100+ systems of Dos, Windows, Linux, BSD, and Solaris (forum thread) can be helpful if you want to stick to an MBR.

接着是丹尼尔B的回答：

Yes, this is possible even with an MBR partition table. There is a special partition type called Extended Partition. It is essentially another partition scheme enclosed in an MBR partition. Wikipedia has a surprisingly detailed description of this scheme.

So long as the boot loader resides on a regular partition, there are no relevant limitati***. Still, some operating systems may throw a tantrum.
