自從裝了Ubuntu和XP雙系統(tǒng)后,變得很麻煩,每次都得在啟動(dòng)菜單上選來選去,浪費(fèi)了不少時(shí)間。
現(xiàn)在想修改使XP成為默認(rèn)的操作系統(tǒng),怎么辦呢?
其實(shí)很簡單,修改 /boot/grub/menu.lst
文件,使其中default值變動(dòng)一下即可。
過程如下:
1、打開命令行終端;
2、輸入:
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak
sudo gedit /boot/grub/menu.lst
注: 第一句做備份用。
3、假設(shè)文件內(nèi)容如下:
-------------------------------------------------------------
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.
## default num
# Set the default entry to the entry number NUM. Numbering starts
from 0, and
# the entry number 0 is the default if the command is not
used.
#
# You can specify 'saved' instead of a number. In this case, the
default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to
'saved' or your
# array will desync and will not let you boot your system.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the
default entry
# (normally the first entry defined).
timeout 10
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu
## ## End Default Options ##

現(xiàn)在default值為0,意即啟動(dòng)排行第一的操作系統(tǒng),這里代表的就是Ubuntu,
kernel 2.6.15-23-386。
現(xiàn)在把它修改成“default 4”,那么XP就成為默認(rèn)的操作系統(tǒng)了。
因?yàn)閺牧銛?shù)起,以title打頭的Microsoft Windows XP
Professional這一行排序?yàn)?。
另外我們還可以通過修改timeout的值來變更默認(rèn)等待時(shí)間。
