grub后有4个选项
我选了“Ubuntu, with Linux 2.6.32-21-generic”，然后闪了段文字，主机闪了一会，电脑就开始黑屏了，没反应，就像主机箱没开着一样
选“Ubuntu, with Linux 2.6.32-21-generic (recovery mode)”也是同样的情况。
用图像界面安装Ubuntu时也是同样的情况
不知道是不是和我的显卡有关系。我的显卡是NVIDIA GeForce 7050 PV / NVIDIA nForce 630a 貌似Ubuntu9.10以后就支持不太好了。
Ubuntu9.04能够正常安装使用，9.10安装花屏，10.04安装黑屏，杯具了
我用Ubuntu9.04的live cd进系统，获得了grub.cfg文件，是这样写的

现在我电脑上有Ubuntu10.04，只是我从来没见过他到底长什么样，连登入界面都没看到过。
汗
今天兴致勃勃的把原先的fedora给卸了安装了ubuntu10.04
