菜鸟询问大侠们:开机问题!

#1

帖子 wyqbeyond » 2008-09-21 21:38

各位大侠,小弟初接触ubuntu,有点问题想要询问。

问题一:小弟电脑装的是ubuntu8.04和XP双系统,但开机默认的启动是ubuntu,请问能修改回XP吗?

问题二:在选择电脑启动系统时,出现了ubuntu8.04.19.....什么的还有个ubuntu8.04.16....一共有5个,我室友也有,但我的似乎比他多两个,是因为我第二次装的时候,没把第一次的格好吗??请问怎么修改阿??(第一次,因为装到一半的时候光驱爆了,后来换了新光驱装来着)

小弟,在此谢过!!

问题一 ,可以,具体请帖出你的 /boot/grub/menu.lst 文件,我告诉你怎么修改。

问题二, 那些是不同版本的内核,一般选用数字较大的启动就是了,如果旧的内核不再使用,可以使用 新立得把它们删掉。

我似乎好像看懂一点....我把一下代码删除.应该就把问题2解决了吧?但我看新立德里面似乎每一项都有两种或者三种,有(muitiverse)(universe)和不加的,旧内核是哪个阿??

删除代码是隐藏起来的,其实旧内核和相关的文件还在系统中,比较正统的删除方式是用 新立得。

提示一下:你如果直接删除 menu.lst的代码,记得更新 default 后面的数字哦,从零开始,数到的 title的个数。。。
