I want to install a second version of Debian on a different partition

My main version is at /dev/hdb9. I therefore installed a second version
at /dev/hda7.
I wanted to make a floppy to boot this but that didn't work. I therefore
added the following entry to my /boot/grub/menu.lst:
title Debian test system, kernel 2.4.27-1-386
root (hd0,7)
kernel /boot/vmlinuz=2.4.27-1-386 root=/dev/hda7 ro
savedefault
boot
However, when I select this at boot it says Error 22: there is no such
partition as (hd07).
Should I change the entry in menu.lst or is there some other way of
booting this partition? I didn't let the installation do anything to my
hard disk because I do NOT want to mess up my main Debian version.

Anthony,
1) are you aware that counting in grub is 0 based ?
2) send us your fdisk -l /dev/hda output
Bob
No, I hadn't realised that this applied to the partitions as well as the
disks. Changing 0,7 to 0,6 seems to work although it now reports a
kernel panic owing to root not being correctly configured. I'll have to
do some more work on this. The above _ought_ to work, I think.
