Disk Partitions with ubuntu

[maxiscool]

hey guys-

So, I have booted Ubuntu, as well as my HD. I opened GParted partition manager, and it will not let me create a partition. the button is just grayed out.

What should I do?

If Partitions are Mounted, GParted will not let you do anything. Boot up from Ubuntu CD and resize partition. Ubuntu CD doesn't mount partition automatically.
in case it doesn't work, Post the output of 'sudo fdisk -l' command here.

I figured out how to make the partitions, and they show up in the Ubuntu installer, but now I get an error saying:

No root file system is detected

Please correct this from the partitioning menu. How do I fix this?

[devils casper]

Select Partition and select / from Mount Point list to assign root ( / ) mount point to that Partition.

Do i do that in Gparted?

No. GParted is Partition Manager only and you can not assign mount points through it.
Create Partition with GParted, format it in ext3 FileSystem. Start Installation and select ext3 partition. Assign / mount point to the partition.
