在安装grub时出现致命错误,grub无法安装,只能从lilo启动。主引导区是hda1,而且在/boot下有gurb目录,里面有文件,如何实现从grub启动?输入grub后提示"grub>",然后怎么做啊?下面hda2报错是怎么回事啊?

$sudo grub-install /dev/hda
试试,注意/boot/grub/menu.lst文件是否存在。不存在就自己写一个。

# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub

## 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'.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)

# Pretty colours
