我装了两个操作系统,Linux和windows XP. 默认是Linux启动,通过下面的操作可把windows XP改为默认启动系统
启动ubuntu后，输入：sudo gedit /boot/grub/menu.lst
然后找到 default 0
然后往下看，找你想默认启动的操作系统！修改default 后面的数字，0对应第一个，1对应第二个，依次往下！以下是我的menu.lst
默认是ubuntu！把0改为4就可以了！
# 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'.
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)
## ## End Default Options #www.gprs5.com#
