双系统出错了

[讲故事的人]

非常喜欢ubuntu ，新版本一出来就下了。昨天抽空装了一下9.10，结果出错了。我的电脑装有vista ，在最后一个分区装linux，以前装过两次都没有问题，这次装完后，vista 无法引导了。每次运行到滚动条消失后就蓝屏。没有办法，vista设置的是蓝屏自动重启，什么也看不到。在网上搜了好久也找不到这方面到信息，难到我是最特别到?这个grub2不好玩阿，一出来就给我下马威，希望各位帮个忙，共同发扬linux人到互助专研精神。
这是我的grub.cfg文件配置：

irc <chenfengyuan|ZN5> say: 那就干脆换成win7好了

是不是改变过硬盘分区的大小了? Windows Vista/7 的引导现在也是使用UUID来认分区的,先用windows Vista 的原版安装光盘修复下bootmgr,再用LiveCD修复GRUB2
