我的ubuntu10.04安装出问题，高手指教！！！

我以前安装ubuntu的时候非常顺利，用wubi安装。可最近安装老是出问题，显示grub> 然后试了网上各种方法都不行，而且老是说kernel安装不成功。请高手帮忙看下！谢了！
还有，我的grub.cfg好像和网上的不一样，请看下！
再补充下，我用ubuntu9.10安装成功过，卸载掉后在安装就不行了，现在安装10.04beta版的也不行。我的系统是xp，用wubi安装ubuntu。

附grub：
#This file is modified at runtime by bootmenu.nsh

set default=0
echo "Completing the Ubuntu installation."
echo "For more installation boot options, press `ESC' now..."
if sleep --verbose --interruptible 5 ; then
set timeout=0
fi
echo

# TBD try to boot directly from kernel/initrd within the ISO via the grub2 loop module

search -s -f -n /ubuntu/install/boot/vmlinuz

好像和网上看到的不一样，不知道为什么？？？？我前面发过帖，第一次不会发，谢谢大家指教！
