Where did those "-1" entries come from?
In all of the entries
hd0 identifies the hard disk where you installed each OS (hd0 being your first, or only, hard disk).
PARTNO identifies the partition where each OS is installed.
If you did a standard Ubuntu installation, I would expect Gutsy, Gutsy Recovery, and memtest86+ to all be on the same partition so all 3 of those sections should have the same "root (hd0,PARTNO)" entry (replace PARTNO with the appropriate partition number).
If you don't know which partitions you installed to, you can open up a terminal window & run:
sudo fdisk /dev/hda
Then, when you see "Command (m for help): enter
All of your partitions will be listed, so you should be able to figure out what's where. To get out of fdisk just enter
Be careful with fdisk. If you enter anything other than p and q you can seriously mess up your partition table if you don't know what you're doing.
