Thanks very much for your reply. I can't get the Interent for my desktop at the moment.
Yes, I used
and I also used
Grub> find /boot/grub/stage1
which return the (hd0,0). Therefore, I think the grub has been installed. Also the output of
are some message like:
grub has been installed successfully...
But the most strange thing is when I use the rescue mode to get login I can't find /boot/grub and "NO" /boot/grub/menu.lst file!!!
It drives me crazy...
Actually, I setup several times of OpenSuse for my laptop and desktop, but this time is really a frustration...
