分区示例:比如分/dev/sda 硬盘
#: fdisk /dev/sda
The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

删除Linux分区方法:做一张partition
magic的启动软盘,启动后删除。或者用win2000的启动光盘启动,然后删除。
