I'm trying to install Ubuntu alongside Windows 7. I made a partition while preparing for the installation in windows of 50Gb. I'm trying to install it right now and after making selecting some space for the swap (i dont know what that is. I'm an absolute beginner and the guide says so) I should now make some other partitions for Ubuntu, but i cant use the remaining space. I'm afraid of deleting anything because the other partitions are from windows.
Right now I can't event access Windows. I'm afraid it might have somehow disappeared.
To be honest what I'm most concerned right now is recovering Windows, but I guess that it is impossible to do so until Ubuntu has finished installing.
