Hallo everybody.

I am a Mandriva user, but I wanted to install KUBUNTU 6.10 as well, so I partitioned my machine like this

hda1 windows XP (sorry but linux can't manage my scanner...)
hdb1 5Gb "/" of Mandriva
hdb2 1Gb Swap for both mandriva and KUBUNTU
hdb3 66Gb /home for both mandriva and kubuntu
hdb4 5Gb "/" intended for KUBUNTU

I obviously told KUBUNTU installer not to format anything and when it comes to selecting the mount points I choose in the scroll menus

"/" hdb4
swap hdb2
home hdb3

but when I tell the installer to proceed I get the message

"missing file system for root"

What did I do wrong?

I assume you did "manually edit the partition table" and I think you need to check reformat for both /dev/hdb4 and /dev/hdb2 (don't worry, swap will still be swap, but I think typically reformatting it makes ubuntu feel better), /dev/hdb4 I believe has to be formatted as a quirk of installing a distro. It has to mark it's territory...

Here's some screenshots of the installer, especially the manual partitioning.

Ok, I'll give it a try.

I gave it a try. Didn't work. I still get the message "no file system for root".

I think it's a bug of the installer. I am giving it up, I don't want to let it do it automatically and forfeiting my other installations.

I had a similar thing happen to me, seems to be a bug that root doesn't like getting installed on partitions that already existed. The fix is when you're in the step to make partitions, you delete the partition that you had and tell it to make a new one there. I would have thought they might have found a a way to fix this by now, guess not.

Where is this option? There is a point where I have to choose between letting the installer do the partitions automatically (which I absolutely DON'T want to do because it took me the best part of a week to get mandriva installed) or "manually edit the partition table", which I had chosen and which leads me to the point where I just tells him where to mount partitions... Maybe there's an option I missed...

Ok, if I remember this right, you would manually edit the partition table.
select the partition you want to install on with the arrow keys and press enter.
With the arrow keys select reformat ext3.
Then select the mount point with the arrow keys witch will be " / " (root)
Do the same for /home or it will mount /media/hd? by default.
Do not reformat home if you have anything on it that your saving.

I thought the option was just before you set the mount points, and after you say you want to edit the partition manually. I'll try restarting with my cd in a bit to see if I can get to that point without installing anything. I'll post back with what I see.

edit: I was right, it comes up right after selecting to manually edit partitions. There's a progress bar, then a screen with the heading "Prepare Partitions" and after this is when you set mount points. The step I was talking about is the prepare partitions step. If you're not getting this I'm not sure what's going on.
