Installing OpenSuse alongside an Ubuntu 10.4

Hallo!
My post is an attempt to acquire some guidance.
I have an Ubuntu 10.4 system installed on a notebook and would like to try OpenSuse 11.3 without disturbing what is installed.
My questions are:
Can I do such an install and where do I find the material, the software I have on a PC-Welt Linux magazine CD?
What is the best and easiest to understand file manager for a newcomer?
What does OpenSuse offer as a simple user interface scheme?
I am not interested in any form of co-habitation with an MS-Win system.
I have such on my desktop and this I will also migrate away from.
And me.
I am a writer and not an IT trained person, but have some computer skills.
I’d be grateful for any useful guidance.
Regards and thanks in advance, patforkin.

Because openSUSE uses the earlier GRUB version and ubuntu uses GRUB2 boot loader, there will be some configuring needed to allow both to boot, this is not difficult, but you should be aware of it.

What is the best and easiest to understand file manager for a newcomer?
This is very objective, but coming from ubuntu, perhaps the one in GNOME for a start, Being Linux you have a number of desktop environments, window managers, file managers etc, etc to chose from, and can have many installed at once.

What does OpenSuse offer as a simple user interface scheme?
I’m not sure what you mean.
openSUSE has one of the best GUI interfaces for administering/configuring an O.S. you could ask for with YaST2.

Can I do such an install and where do I find the material, the software I have on a PC-Welt Linux magazine CD?
11.3 is fine and supported for some time yet, but 11.4 is out software.opensuse.org: Download openSUSE 11.4
so you may consider downloading one of the liveCDs to install from, and read Start-Up and openSUSE 11.4 Release Notesand the sticky’s here New User How To/FAQ (read only)
