virtualBox开机挂载windows分区，并把光盘镜源设为源。
设置fstab文件。把windows的d,e,f盘分别开机挂载到了/misc/d /misc/e /misc/f 。/misc是自建的目录，是miscellany的缩写。
# cat /etc/fstab

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
