grub reinstalled but in shell mode, can't load ubuntu or windows

[daudiam]

I had Ubuntu 9.04. But when I installed Windows also, the grub was overwritten. To reinstall the grub, I took a live cd of 9.10 and typed the following

sudo mount /dev/sda8  /mnt 
sudo grub-install --root-directory=/mnt  /dev/sda

No error message came, but when I restarted my computer, it showed

GRUB 1.97~Beta4

sh:grub>

Perhaps its the command line mode of grub. I want a graphical mode so that I can easily boot either Windows or Ubuntu.

Is there any way or should I just reinstall ?

What does this command tell us:

sudo fdisk -l

Try reinstalling it again like this:

sudo grub-install --root-directory=/mnt/ /dev/sda

You may have left out a forward slash.
