Use a partitioner to delete the old Ubuntu partition, this is safe as long as your installation's GRUB points to vista and the new Ubuntu (which is true provided you reinstalled GRUB with the new Ubuntu partition)

All new problems require investigation, and so if errors are problems, try to learn as much as you can and report back.

I'm with NW here, I'd just delete the old one... of course I'd also resize one of the other ones (how did you get 3 anyways?).

You -could- reformat the recovery drive, and it's perfectly safe but it's so much easier to recover/format the windows partition (assuming that's the one it's for) and I would hate to do it via cd and finding drivers if it crashed. That would be a pain.

GRUB should be correctly set up. verify with sudo fdisk -l which partition is the old Ubuntu, then you can remove that one using anything you like, you may be able to do it in Ubuntu because the old one will not be mounted.

Look in the GRUB manual on how to edit entries (to delete the old one) after.

If hes using the latest version of Ubuntu then he would be using GRUB2, which can autodetect installed Operating Systems. He should instead just run the update-grub command and have GRUB autoconfigure new menu entries for him.
