14.10显卡驱动有问题
1.恢复启动引导菜单：启动盘 -> 运行到分区之前，不要分区 -> shift+f10 进入dos -> bootsec /fixmbr ->关闭重启。
2.easyBCD:
title Install Ubuntu
root (hd0,0)
kernel (hd0,0)/vmlinuz boot=casper iso-scan/filename=/ubuntu-14.04-desktop-i386.iso ro quiet splash
locale=zh_CN.UTF-8
initrd (hd0,0)/initrd.lz
注意iso-scan是连在一起的
3.分区: /，swap，/home 都是逻辑分区
4.更新源
cp /etc/apt/sources.list /etc/apt/sources.list.bak
gedit /etc/apt/sources.list
