[ubuntu] Error: No such partition (Grub rescue) on a notebook

view story

http://ubuntuforums.org – hi all, While formatting my notebook, i accedentely unplugged it before it was finished :(, so now i'm getting the error "Error: No such partition (Grub rescue)", doesn't matter if i boot from the hard drive or a USB stick with Ubuntu on it (tried with windows too) i always get the same message! All the solution i have found so far include booting from a live CD wich isn't an option for me. HEEELP!!! thank you for your time. (Hardware)
