	Well, I did it; I wish I knew more exactly *how* I did it. I'll 
outline it, and maybe one of the gurux here can generalize and polish it 
into a real recipe.

	I did DBAN the whole hard drive before anything else.

	Previous failures taught me the reverse. I installed CentOS 
first, with manual partitioning, creating a /boot partition, a main one 
for C5, and a swap partition -- leaving the rest of the space free, iirc. 
When I got it through firstboot, I did a little minimal configuring, to 
have a usable desktop and a couple of things I expected to use, such as 
gparted a/o qtparted.

	Then I installed F8, again with manual partitioning.

	When I got it through firstboot and another minimal 
configuration, I rebooted another time. Sure enough, booting to C5 now 

	So I set up a gnome terminal with two tabs each su'd to root, and 
another workspace with gparted running -- not doing anything, just 

	I opened F8's /etc/grub.conf with a text editor on one root tab; 
on the other, I did "mkdir /TEST" followed by "mount -t ext3 /dev/sdax /

	Then cd /TEST, followed by ls and cd some more, till I got to a 
grub.conf or a menu.lst

	(NB:you have to use sd in F8, where you'd use hd in C5 or U7; 
start with x = 1, and keep looking till you can see from the file names 
that you're in the one for C5; there is no space between the third / and 
	At that point, with c&p between the tabs, I cloned an entry for 
C5 into the configuration for F8.

	Then I cd'd out of the mounted partition, unmounted it, and 
rebooted to make sure. Now C5 and F8 did both boot successfully.

	So I installed U7, again with manual partitioning; it insisted, 
as the others had not, on making an extra partition -- God knows why. I 
bit my fingernails, and kept going.

	After the install, to no surprise on my part, I could boot to 
both F8 and U7, but C5 had disappeared.

	Now comes a (probably evitable) heresy. 

	I booted to U7's rescue, or minimal, or whatever; got to the root 
prompt at the end of it; commanded "passwd" and gave it a root password; 
and rebooted into regular U7.

	Now I could again set two terminal tabs to root. 

	Those of you actually comfortable with sudoing, and not worried 
about timing out while you study things at length, may want to skip the 
heretical root password.

	Again I launched gparted (which I had had to get from synaptic) 
to look with -- and this time mounted both U7's own partition and one of 
the others. (I had to do it that way, because I didn't find a way to 
simply cd from root to what turned out to be /boot/grub/menu.lst; but 
with U7's partition once mounted under /root, I could edit it.)

	Now I got to the bottom of menu.lst, below the F8 entry which I 
knew worked; and copied/cloned an entry for C5 onto the bottom of it.

	When I got back out of everything, lo and behold!, all three OSs 
did boot successfully.

	I never found one. I'm not completely sure where the one that 
works is, but I believe (once I finish customizing) I'll be able to get 
to it and post it or email it, if anyone asks.
