Ubuntu安装后双系统启动顺序的修改

其实修改Ubuntu安装后的双系统启动顺序很简单，修改 /boot/grub/menu.lst 文件，使其中default值变动一下即可。

过程如下：

1、打开命令行终端；

2、输入：

sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak

sudo gedit /boot/grub/menu.lst

注： 第一句做备份用。

3、假设文件内容如下：

# 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 ##
