- fdisk /dev/sdb
"d" 删除全部分区
"n" 创建遍及整个磁盘的主分区1
"t" 设置文件系统为FAT32（LBA），代码为"c"
"a" 设置主分区1的Boot标记
"p" 打印分区表
结果应类似下表：
Disk /dev/sdb: 8076 MB, 80761322352 bytes
186 heads, 28 sectors/track, 3028 cylinders
Units = cylinders of 5208 * 512 = 2666496 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 3029 7885824 c W95 FAT32 (LBA)
"w" 写入分区表并退出
注意:如有疑问可以参考最后的 fdisk 详细过程。
3. 使用FAT32文件系统格式化U盘
- mkfs.vfat -F 32 -n ESXi /dev/sdb1
4. 安装syslinux并写入MBR
- syslinux /dev/sdb1
- cat /usr/lib/syslinux/mbr.bin > /dev/sdb
5. 挂载U盘
- mount /dev/sdb1 /mnt/usb
6. 挂载ESXi安装程序ISO镜像
- mount -o loop VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso /mnt/iso
7. 将ISO镜像的内容复制到U盘
- cp -r /mnt/iso/* /mnt/usb/
8. 将isolinux.cfg文件重命名为syslinux.cfg
- mv /mnt/usb/isolinux.cfg /mnt/usb/syslinux.cfg
9. 编辑syslinux.cfg 文件
- vim /mnt/usb/syslinux.cfg
在/mnt/usb/syslinux.cfg 文件中，将APPEND -c boot.cfg 一行更改为 APPEND -c boot.cfg -p 1。
10. 拷贝一个新的menu.c32文件到U盘，覆盖原来的文件
- cp /usr/lib/syslinux/menu.c32 /mnt/usb/
注意:这步并不在VMware vSphere官方手册 中，如没有此步骤，引导时会出现“menu.c32: not a COM32R image”这样的错误。
11. 卸载U盘
umount /mnt/usb
12. 卸载ISO镜像
umount /mnt/iso
完工:现在U盘可以引导安装ESXi 5.1 了
