各位大虾看下这个双硬盘双系统问题

[dshgk]

本人的机器是IBM T40（1.5,512)

现在是两个硬盘，主盘是UBUNTU，从盘是XP。

现在用UBUNTU多了，XP就放在一边，但有时候又不得不拿XP出来用下。现在不知什么在UBUNTU的GRUB里面设一个XP的启动项，不用我成日F12去选硬盘（从盘放在光驱的位置），这个选了XP后就不能启动。

本人的MENU.LST

# 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/black white/blue

#A splash image for the menu
splashimage=(hd0,0)/boot/grub/splashimages/secae382.xpm.gz

## 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/
# password topsecret

### 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=f897ba36-d8b6-4c06-8cb4-d90afaa6c7e7 ro

## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)

## 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=locale=zh_CN vga=769 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

## 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 ##

先多谢楼上的大虾，但改了试过，开机选择后出现：

Starting Up ......

_

然后光标就在那时闪，用F12选择就可以分别启动
我觉得MENU.LST是没写错，不知是不是还有什么未设的。

这是FDISK －L 的结果

加上红字部分

[dshgk]

可以了，好高兴，谢谢你。

不过不太清楚这个map (hd0) (hd1) 是什么意思，是不是MUNT硬盘？

[leeaman]

基本上就是把两个硬盘通过映射方式来互换主从盘关系

[dshgk]

原来这样，又学东东了，谢谢。

这个不需要一个中间值么？

[leeaman]

你当是编程啊,要用一个中间变量来两个变量互相赋值啊
