的默认启动项

作者:操作系统

装过Ubuntu 9.10 的就知道 Ubuntu 9.10使用了 grub 2,是个测试版的,原来的sudo gedit /boot/grub/menu.lst 已经没用了,现在的文件是放在/boot/grub/grub.cfg 下的,用这个命令就可以了,sudo gedit /boot/grub/grub.cfg
当然,你也可以手工在文件中查找到这文件,再编辑,grub.cfg是只读的,如果你是第一次修改,要先设置可写
sudo chmod 744 /boot/grub/grub.cfg之后再修改就不用了,这个是我的配置,Ubuntu 9.10 + Windows 7,其实只是删除了几个老的内核启动项,从装好 Ubuntu 9.10到现在,linux内核已经升级2次了,感觉上面的东西其实在太多了,一般我都是用Ubuntu,如果你需要修改顺序,让Windows 7 默认启动的话,你把 set default=”0″中的 0 改为你的Windows 7所在位置就可以了,我的应该是 5
