如何修改menu.lst?

#1

帖子 罗非鱼 » 2008-10-28 21:23

我用文本编辑器打开boot\grub\menu.lst后;修改了menu.lst
保存时出现错误;
You do not have the permissions necessary to save the file.
Please check that you typed the location correctly and try again.
请问我应该这么办;我准备修改配置文件来做多重引导的?
请大侠赐教

没有权限,运行

代码: 全选

sudo gedit /boot/grub/menu.lst
连sudo也不知道,小心点啊,注意备份。

。。。。楼上说的对,没有用sudo。既然这样,建议楼主先对menu.lst做个备份。

代码: 全选

sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.bak
然后再对menu.lst进行操作,这样失败以后进不去系统的话,还可以通过Live CD进入Ubuntu修复回来。具体的修复方法如下:
先查看Ubuntu所在分区:

代码: 全选

sudo fdisk -l
然后将得到的Ubuntu分区挂载到/mnt下

代码: 全选

sudo mkdir /mnt/ubuntu
sudo mount -t ext2 /dev/sdaX /mnt/ubuntu
然后将menu.lst.bak恢复为menu.lst

代码: 全选

sudo cp /mnt/ubuntu/boot/grub/menu.lst.bak /mnt/ubuntu/boot/grub/menu.lst
执行完成之后Umount Ubuntu的分区,然后重启即可

代码: 全选

sudo umount /mnt/ubuntu
sudo reboot

我特地来看三楼的解答,以前还担心不能进入系统呢,现在可以放开去修改了!

# 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'.
# WARNING: If you are using dmraid do not use 'savedefault' 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

# Pretty colours
#color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=ba8ab832-874d-4c60-b9a0-1f93513a559e ro locale=zh_CN

## default grub root device
## e.g. groot=(hd0,0)
# groot=ba8ab832-874d-4c60-b9a0-1f93513a559e

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

## ## End Default Options ##
