I'm trying to install Ubuntu 10.10 from Live CD.
I can access the partitions already created ( two NTFS and one ext3 prepared ), but when I'm trying to install, at the step where I should select the partition, I don't have from where to choose.
The list is empty, as you can see in the screenshot below:

Open GParted, System>Administration>GParted and take a screenshot of your partition set up please. – Col Feb 6 '11 at 11:51
A mounted partition would (probably) not be accessible to the installer. Try unmounting it first. – oKtosiTe Feb 21 '11 at 19:32

"I can access the partitions already created" -- does that mean you mounted them?

The installer doesn't like your volumes mounted - gparted will error.

I suggest setting up a new partition table with the installer, as long as it not gonna mess up your Windows partition.

$ mount  

will show you all your mounted partitions

$ umount /dev/[sda*]  

repace [sda*] with your disk/partition identifier. will umount your partition.

umount the partitions to get access to them in the installer.

Or right click the partitions in nautilus and click umount them to make them available in the installer.
