XP和LINUX双系统,无法进入XP,求救中
我在XP下安装了双系统,结果XP就进不去了,我是用PM分区之后光盘安装的UBUNTU8.10,结果选择XP时,就不断地重新回到操作系统选择界面,根本无法进入XP系统,搞得快崩溃了,各位高手指点一下啊,多谢了

望高人予以指点,我已经自己弄了一天,都没有成果,xp还是在选择进入之后立即又重新启动,汗颜中ing,希望能够尽快解决,感激不尽!

不管是几个系统,只要其中一个是Win,那就老实点,用Win的引导器吧,把其他系统的引导安装在各自的分区的引导记录上,不要装在MBR上,然后dd出来。
或者干脆用grub4dos的grldr.mbr来引导,各非Win系统也就不要装各自的引导器了。
总之一句话,有Win在,惹不起总躲得起啊!
和楼上某人一样,推荐用rootnoverify试一下。
不过,双系统的时候,以我的经验,如果有Windows存在,你最好是把引导交给Windows。
GRUB之类的Linux引导器不要装在MBR上,而是装在Linux的/boot的所在区的引导上,然后用dd导出成文件
大概是这样写的,很久不用,可能有错:
dd if=/dev/sdX of=/dev/sdY/mbr.bin bs=512 count=1
然后把mbr.bin放到Windows所在盘(一般是C:)的根目录下,然后用Windows的引导器去引导这个mbr.bin
如果可以的话,重新安装一次 ubuntu就行了
很简单,进PE,然后用个启动修复软件,修复一下就可以了
LZ是怎么安装顺序安装的呢。

以下方法来自于
kookc 的 blog:重装win而不改变ubuntu的引导
http://kookc.blog.sohu.com/72190446.html
由于感觉到将grub装到mbr影响了我的电脑的启动速度,主要是主板自检吧!
出现logo好慢。
今天将mbr拷贝了出来,然后fdisk /mbr(M$ dos)按照M$的标准修复了mbr
启动快了
然后用会nt的引导,又没破坏linux的引导!
重装系统也好恢复了!
下面的操作步骤!
首先起确认你的grub正常,并能启动linux
然后启动到linux (Ubuntu)
如果你的是IDE硬盘 (谢谢sun391补充)
代码:
sudo dd if=/dev/hda of=/media/linux.lnx bs=512 count=1
如果你硬盘的被识别为sda
代码:
sudo dd if=/dev/sda of=/media/linux.lnx bs=512 count=1
题外话:如果没有bs=512 count=1的话,dd好像跟ghost一样,不知道是不是哦,高手赐教 kookc
然后你可以到/media找到linux.lnx这个文件
将它cp到你的win根目录,例如是C:,而且我建议你对这个文件做多个备份!
然后重启到win
进入后确认你的系统根目有linux.lnx这个文件
然后修改boot.ini
boot.ini请在win 下修改,因为编码不同! 大侠除外 kookc
它可能隐藏和只读
然后在后面加入
如果有
代码:
time=0
请将0更改!如time=5
代码:
C:linux.lnx="linux"
保存
然后你就可以reboot看效果了
nt的引导菜单会出现linux这一项,选择后好像又会到grub的菜单了
事实上它只是读了linux.lnx
上面这个确认能进入linux后你就可以选者性的对mbr做M$的恢复了
win9x的引导盘是
代码:
fdisk /mbr
而nt就是用安装光盘或别的方法进入修复控制台
然后
代码:
fixmbr
这样你的mbr 就跟只装win的一样了!
如果你对win重装了只要做
拷尼备份的linux.lnx到win的根目录
并修改boot.ini (修改在前面已经有了)
