9.10的时候，我很喜欢grub2的记住上次启动项，那么10.04继续咯，于是gvim /etc/default/grub ==> grub default=saved ==>update-grub
重启，再重启，再再重启，悲剧的grub默认永远是第一条ubuntu～～～
难道是我重装过win7的缘故？（grub2蛮高级的，重装win7，依然是grub2引导，不会被loader覆盖！）
于是重装ubuntu10.04，重启再重启，依然无效～～
后来看到报道，据说10.04发布前夕发现一个跟windows引导有关的bug，需要重新打包，说bug其实也不算bug，难道，悲剧在这里？
5月18日，重新下载ubuntu-cd，重装之，经过N小时的更新和安装软件，gvim /etc/default/grub ==> grub default=saved ==>update-grub
重启，再重启，再再重启，悲剧啊悲剧，难道哥RP就那么差？
贴出悲剧grub.cfg，大家帮我分析下：
