How to partition drive for installation?
I have successfully installed the livedisk version of Ubuntu 12.04 (from a usb) to my windows machine, which previously ran Windows 7. I wish to completely erase Windows 7 for Ubuntu. When I try to fully install, I am told to choose Installation Type, which means partitioning. The issue is that I cannot click any of the options to add or remove partitions, and the dropdown menu for "Device for Boot Loader Installation" reads /dev/sda, but cannot be changed. Without this partition, my computer won't install the full version. Any ideas? Thanks!
You don't mention where you are attempting to do the full install from....

If from installation already on your machine, partitioning will fail as partitioning can NOT be done on a mounted drive.
If from liveCD/USB then probably a glitch in the installer.
Having had bad experiences in past with installer/partitioners I pre-partition disk before running install media then choose 'custom install' or 'use existing partitions'.
Gparted works well for this-
