求助：双系统grub引导被删除了，如何恢复opensuse的引导

SH_晴空

用diskgen弄分区表的时候不小心把grub弄没了，现在只能进xp。
尝试过用grubfordos+从opensuse中提取的menu.lst引导，但是提示找不到文件。这是从linux根目录 /boot/grub里提取的menu.lst:

# Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader

default 2
timeout 8
gfxmenu (hd0,8)/boot/message
##YaST - activate

也试过用安装文件恢复grub，但是出现与grubfordos 一样的问题，说找不到文件（我用的iso硬盘安装）。求助各位看看有什么办法可以恢复opensuse系统。

另外实际在grubfordos中可以看到“/"应该在(hd0,7),hd(0,8)是/home （linux分区是swap+"/"+/home)，和menu.lst不一样，不知道怎么回事

观世音

可以用安装光盘启动后选择安装，之后会有选项选择是全新安装还是更新，选更新即可。

这个已经我试过了，的确修复了grub引导界面，但是还是提示找不到文件，也就是/boot/vmlinuz-2.6.32-12-desktop.但是显然文件是存在的。我用r-linux查看过

呃~
楼主的 /boot 到底在哪个分区啊？你说修复了grub引导界面是什么意思？
如果 /boot 是在 (hd0,7) ，为什么 gfxmenu (hd0,8)/boot/message 会没问题呢？
如果只是 menu.lst 错了的话，修改一下不就行了吗？
嗯~
是不是由于楼主用diskgen修改分区表，导致openSUSE所在分区的编号发生了变化？

SH_晴空

看来应该是diskgen弄得了。原来我的xp有4个盘c,d,e(software),f(backup)，
装suse的部分是从e盘分出去的，在e、f之间。
记得安装opensuse时将格式化好的3个分区跟在了f盘后,也就是hd0,6(backup),hd0,7 swap,hd0,8 "/",hd0,9 /home,
结果diskgen调整为hd0,5(software),hd0,6 swap,hd0,7 "/",hd0,8 /home ,hd0,9 (backup).
当时打开diskgen是要备份分区表的，结果它提示不规则的分区顺序，当时也没多想就点了修改。没想到搞成了这样
还是不了解惹得祸啊。
看来不得不重装了。

既然 / 只是由8变成7了，你把menu.lst中对应的都改成7不就行了吗？

shuxiangmeiying

xp里安装个EASYBCD和.net2.0,编辑EASYBCD目录下menu.lst文件也可以。

vsu

dd if=/boot/grub/mbr_backup*  of=/dev/sda count=1 bs=446

光盘启动，修复时啥都不勾选，它会自动安装引导的
