[SOLVED] Two Disks Two Versions of Ubuntu? No Mr. Bill

[Tom Atkins]

I started with Suse 10.0 when I purchased it several years ago. When they stopped supporting it I looked around for another Distro. After examing several I settled on Ubuntu. I purchased the DVD for HH on Amazon and installed it on sdb. I have been very pleased with it and now I would like to install it on sda (overwriting Suse), and updating it to the newest version just to see what 10.0 is like. I intend to keep using HH as my production version. I do not want the new install to mess up GRUB. Here is some info about my system:

So you want to get rid of Suse 10.0 and install HH in it's place. You also want to upgrade to 8.10 (II) to see what it's like?

I suggest you download and burn Intrepid Ibex and install it on sda. Gets you where you want to be in one giant step, using just a little step.

HH (8.04) is an LTS version, which means you get 3 years support (until (where is my calculator) April 2011). II is a normal version, which gets you support during 18 months, and now my calculator is gone. Using an LTS version will leave you with a rather "obsolete" version in it's latter years, however, but being an enterprise version is maybe a little more stable (use HH 8.04.1, for me 8.04 was rather soso, freezing every other moment).

So it is all up to you, I would do it the easy way (20 minutes, and some extra time to download and install the updates, and the applications that you want).

(the added use of my reply is another bump :) )

What I am most interested in is guidance on how do the install without messing up my GRUB menu.

Hello Tom,

How are things going now? Would be nice if you could let us know. We on the forum learn from such messages too, you know :)

If my answer was quite off the mark, that would mean that I'll learn from your answer that it was....

I wish you success.

Hi Tophiso,

I have not done anything yet, I was away a couple of days. Your reply was the most practical way to go but I wanted to go through the install and update route just to see what if any problems I would have. I am mainly concerned with doing the HH install on the disk Suse is on and not being able to boot what is my Production version.

[psusi]

Just install the new system, then edit your menu.lst to put the entries back for booting the second drive.
