安装W2000时，把GRUB丢了，如何恢复GRUB？

tmcco

boot with your rescue disk(fdd) or your installation cdrom and run grub-install to fix.
if you are unsure on grub's path, try this:
#find / -name grub*

[root@localhost grub]# fdisk -l

只有一个硬盘，hd1,hd2,hd3都是主分区。hd1和hd2分别是2个不同版本的winxp. linux9装在hd3里面。

我今天把hd2里面的winxp重装了一遍以后，grub就没了。

而且，我没有给硬盘划分boot分区！！！
怎么办？？

tmcco

#grub
grub>root (hd0,2)
grub>setup (hd0)
grub>quit
#reboot
!!ensure that your grub.conf is correctly configured!!

谢谢   tmcco兄及其他各位朋友，已经搞定了！

不过，我还是不太理解
grub>root (hd0,2)
grub>setup (hd0)

能不能具体讲讲那个2是怎么来的？

tmcco

in grub "hd0" means hda in linux, so "hd1" for hdb...
in grub "(hd0,0) means first partition of hd0 (linux:hda1)
so (hd0,1)->hda2, (hd0,2)->hda3.....
your linux root(/) partition is /dev/hda3, so that the /boot/grub is in /dev/hda3 too, the "root (hd0,2)" specifys that grub shall find in hda3, and "setup (hd0)" means install the grub loader to the hda's MBR.
you may read the grub manual for details.
