Ubuntu Fix Grub

which is known to present some problems due to lack of efficient poulsbo drivers. By following the instructions in the official documentation of Ubuntu, I managed to reach a working live CD environment and install Xubuntu. The next step I had to follow was to edit a grub text and then update grub for the changes to take effect {If I discarded this step, grub wouldn't load, giving me an error message which I will mention if needed}. Unfortunately, when I used "sudo update-grub" to update it, the following error came up: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). I mounted all the filesystems yet it didn't help. I tried running grub-probe by double clicking it, but again it didn't seem to run, nor was grub updated since it kept giving me the same error. I googled the error a bit, but although I tried a thing or two, it was no use. Any help would be appreciated.

What's Grub2 doing on a separate partition? Any particular reason it's there? Is it really there? By the way, this is the way to reinstall GRUB.
