master boot record

基本解释

Repair the file system boot sector or the Master Boot Record (MBR).
修复文件系统启动扇区或主启动记录 (MBR)。
My disk now has a master boot record and I'm ready to create new partitions, called "segments" in EVMS-speak.
现在我的磁盘有一个主引导记录，然后准备创建新的分区，即 EVMS 行话中的“段”。
This limitation is due to something called the Master Boot Record which tells the computer which partitions it can boot from, and so primary partitions are usually reserved for operating systems.
这个只跟硬盘有关，跟操作系统是什么没有关系。主引导记录告诉机器从哪里启动系统，所以一般来说主分区是安装系统的。
