Hi, I've recently bought a Compaq laptop. It currently has Windows 7 installed and I want to dual boot with Ubuntu.
Unfortunately, Compaq have already partitioned the hard disk into four partitions. The largest partition, which is 480GB is the second. If I begin the installer, and resize the second partition to create free space, then I'm told that it is "unuseable". I believe that the extra partitions are for recovery etc.
The partition is probably tagged and formatted with NTFS - delete it from within Windows to be sure it is the right (empty!) one. When you start the Ubuntu installer again it should see the hole.
Good luck, Tim.
