将ntfs分区转换为ext4分区

叮叮

[root@fedora15 zou]# fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors

/dev/sda9 403730432 488390655 42330112 8e Linux LVM

现在，要把/dev/sda7 ，即F盘的NTFS格式转换成ext4格式，归linux使用。方法：
umount /dev/sda7

用fdisk转换分区格式，改为8e
fdisk /dev/sda
Command (m for help): m (这里有m可以看一下各个参数的意思)
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id //这个t就是偶们要用的
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)

下面就是要用t命来修改下分区的id
Command (m for help): t
Partition number (1-10): 7 //这个是分区号
Hex code (type L to list codes):8e // 8e是Linux LVM 的id，可以敲一个“L”查看一下，这样分区的格式就转换完啦。
Command (m for help): w
可以看到/dev/sda7分区

格式化分区：
mkfs.ext4 /dev/sda7

创建/jackzou19目录：
mkdir /data1

挂载分区：
mount /dev/sda7/home/jackzou19
然后挂载好，现在的情况如下：

[root@fedora15 zou]# df -h

文件系统 容量 已用 可用 已用%% 挂载点

/dev/sda5 55G 38G 17G 70% /media/My
/dev/sda1 31G 27G 3.6G 89% /media/Fuck

fuck my life 分别对应这windows系统下的C、D、E盘。

最后设置系统自动加载
