启动不了（已解决）

[boycc1974]

电脑上先安装的XP（C盘），然后我安装了UBUNTU。UBUNTU的启动菜单能正确识别XP，现在我在2个系统的情况下又安装了WINDOWS7（F盘），现在WINDOWS7的启动菜单只能认出WINDOWS7和XP了。
ubuntu@ubuntu:~$ sudo fdisk -l

Partition table entries are not in disk order
ubuntu@ubuntu:~$ sudo grub
Probing devices to guess BIOS drives. This may take a long time.
ubuntu@ubuntu:~$ sudo grub

以前装xp的时候，用livecd修复，
一般：
grub>
root (hd0,0)
setup (hd0)
就搞定了，
但是现在装了windows seven后，用livecd修复不了~~~

帮我看看怎么解决啊！O(∩_∩)O谢谢
功夫不负有心人，已经摸索解决多层启动，恭喜下自己

貌似分区表出问题了
