How to get back to Ubuntu ?

[knguyen144]

I "made" a mistake to switch from Ubuntu 8.04 to Kubuntu 8.10 due to all hypes about KDE 4.x ...
Kubuntu 8.10 installation is OK, I have no problem. However, I ran into a main problem is I am working on SystemC Verification tool which was working fine on Ubuntu 8.04.

When I switched to Kubuntu, I can't reinstall the SystemC, eventhough the software package have not changed.
In Ubuntu 8.04, I used GNU 4.2 Compiler, in Kubuntu the GNU 4.3 was installed. The GNU 4.3 compiler find something mismatches such as:

The SystemC source files were not changed since 6/2008 from Open SystemC Initiative (OCSI).
I was thinking about to reinstall Ubuntu 8.04, but the installation won't allow me to install over the Kubuntu 8.10 volume.
I am so scare of the repartition during my first attempt to reinstall Ubuntu 8.04: it asked me to use the whole harddisk which I am dual-booted with WindowXP. I am looking for alternative choice to install over the Kubuntu logical volume.
I can't afford to loose the Window data, back-up the Window is not a choice. I can't take that risk.

I need both OSs alive for my work.

Please help.

Install; go 'Manual' and pick the Kubuntu partition(s), assign mount point '/' and /home if you have it in kubuntu; then follow with the installation. You can ignore /swap.
Remember to save data and backup everything first.

That is what I am looking for, I got to that point, but I did not know what to do next ...

Let me ask a little more in details:
I must assign mount BOTH points "/" and "/home" so I won't face the rejection: "no system root available" or something like that to save the setup before move on the installation ?

Thank.

One partition with mount point '/' will do it.
