I'm trying to create a dual-boot machine, having Linux Mint 12 installed already. I have only one partition that occupies the whole hdd space. I want to cut some space from it and create a new partition for windows, but in gparted all options for this partition (delete, resize/move) are disabled. What should I do to create the new partition?
How you are trying to accomplish this task? on booted up host system? If yes, You should start system from CD (ubuntu or similar) and then resize partition
