Command (m for help):n 
Command action 
　　  e  extended         //输入e为创建扩展分区 
　　  p  primary partition (1-4)   //输入p为创建逻辑分区 
p 
Partion number(1-4)：1   //在这里输入l，就进入划分逻辑分区阶段了； 
First cylinder (51-125, default 51):  //注：这个就是分区的Start 值；这里最好直接按回车，如果您输入了一个非默认的数字，会造成空间浪费； 
Using default value 51 
Last cylinder or +size or +sizeM or +sizeK (51-125, default 125): +200M 注：这个是定义分区大小的，+200M 就是大小为200M ；当然您也可以根据p提示的单位cylinder的大小来算，然后来指定 End的数值。回头看看是怎么算的；还是用+200M这个办法来添加，这样能直观一点。如果您想添加一个10G左右大小的分区，请输入 +10000M ； 
 
Command (m for help): w           //最后输入w回车保存。
