問題描述：
Ubuntu 10.04發布了，隨即裸機安裝了Windows XP ，然後用U盤啟動盤安裝了Ubuntu 10.04,安裝速度飛快(不到10分鐘吧)，但是裝上後發現在grub啟動項裡沒有XP，郁悶了，花了幾分鐘終於解決了，呵呵~
以下是修改後的grub.cfg, 依照個人分區情況不同進行修改~~
進入Ubuntu10.04，在終端中鍵入以下命令，
sudo gedit /boot/grub.cfg
對比以下修改相應的XP啟動項，保存退出，然後就OK了!
---------------------------------以下為grub.cfg的內容：-------------------------------
