Hi Jason, I followed your advice and it worked - thanks again! However, being unfamiliar with partitions I have got into a muddle by trying to erase things. The operating system is now called Disk 2 and it is 338.5 GB. 550GB is occupied by green “untitled” and 5GB is orange “untitled” and 50 GB is red “untitled”. The (now) empty “Mackintosh HD” is 14.21GB You can probably clearly see how I’ve messed things up by sliding around the pie chart! How do I get rid of all the partitions now and let the operating system (now called Disk2) have access to the whole drive?
