    Earlier today I changed the size of my bootcamp partition because I completely ran out of room. Well, I only made it about a gig or two larger and somehow it got filled again without installing anything. (I have all of my downloads and installs on my external hard drive.)

    Now when I go to change the size again I get the message, "You can't resize the partitions on this disk because it uses the Master Boot Record partition scheme."

    Is there anything I can do to fix this? I really don't want to re-install Windows all over again and install all of my Steam games again...

    Thanks for any help.

    Question 1: How did you resize it? i.e. what utility did you use.

    Question 2: Use the following command in terminal and post the results properly formatted using CODE tags. After pasting the text, highlight it, and click on the # button in the toolbar to add the code tags.

    Code:
    sudo gpt -r -vv show disk0
