求教先装ubnutu 用grub引导Xp的问题？

[yy0011]

sudo fdisk -l 结构如下
Device Boot Start End Blocks Id System
/dev/sda1 * 1 24 192748+ 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 3953 19457 124543912+ f W95 Ext'd (LBA)
Partition 2 does not end on cylinder boundary.
/dev/sda3 25 148 996030 82 Linux swap / Solaris
Partition 3 does not end on cylinder boundary.
/dev/sda4 149 3952 30555630 83 Linux
Partition 4 does not end on cylinder boundary.
/dev/sda5 3953 7904 31741952 7 HPFS/NTFS
/dev/sda6 7905 13004 40960048+ 7 HPFS/NTFS
/dev/sda7 13004 19457 51838888+ 7 HPFS/NTFS

ubnutu正常启动，之后我用ghost xp盘将xp ghost 到 /dev/sda5 上。
通过sudo update-grub 更新grub.cfg得到
menuentry "Microsoft Windows XP Professional (on /dev/sda5)" {
insmod ntfs
set root=(hd0,5)
search --no-floppy --fs-uuid --set 8c682b7b682b62e6
drivemap -s (hd0) ${root}
chainloader +1
}
菜单项
但是启动时选择这个菜单，就是黑屏没反应了，求教大家帮忙如何处理？
