I am using a dual boot setup (Windows 7 and Ubuntu 12.04 LTS).
The first two partitions belong to Windows and the third and fourth are the ubuntu system and swap partions respectively. All of these are primary and there is remaining unallocated space.
My plan was to allocate the remaining space as a shared partition for both operating systems, but since I defined all of the current partitions as primary, this is not possible (max. 4 primary).
Is is possible to create a new primary partition from the ubuntu swap partition and the unallocated space, and place the new swap partition inside - or will this break my system?
I know that logical swap partitions are possible, but not if such a change is possible retrospectively.
