8.04

Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now).

But... it won't let me!

When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume.

It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb.

Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system).

Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it.

Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help.

I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted as "busy" or "locked".

Any idea how to solve this problem?
