vi /var/lib/tftpboot/pxelinux.cfg/default
末尾添加：

menu label ^pxe

vi /var/lib/tftpboot/pxelinux.cfg/default 启动界面在这修改
  default linux        # 默认启动的是 'label linux' 中标记的启动内核
  prompt 1             # 显示 'boot: ' 提示符
  timeout 60          # 等待超时时间，单位为 1/10 秒,超时后自动启动 默认指定的label     
  display boot.msg    # 显示boot.msg的内容，文件路径是相对tftp server 的根目录(默认 /tftpboot),所以boot.msg文件绝对路径在 /tftpboot/boot.msg

menu.c32 提供类菜单模式的功能
pxelinux.0  开机管理程式
pxelinuxcfg 开机的选单设定
vesamenu.c32 图形化界面菜单
vmlinuz  安装软件核心文档（kernel file）
initrd.img 开机过程所需要的模块参数
isolinux.cfg -->demo  作为pxe所需开机菜单

--size 规范分割的大小
--grow 系统自动去判断最大可用容量，然后通通分给该分区
--asprimary 将该分割强制列在主要分割类型中
--grub-crypt   rootpw密码获取
part / --fstype ext3 --start=1 --end=250 --ondisk=sda  根分区类型、挂载点、大小
part /home --fstype ext3 --start=251 --end=1000 --ondisk=sda
part /usr --fstype ext3 --start=1001 --end=5000 --ondisk=sda
part /usr/local --fstype ext3 --start=5001 --end=7000 --ondisk=sda
