Q: No partitions showing up in Boot Camp in Yosemite

I am trying to use Boot Camp on Yosemite to install Windows 8. When I launch Boot Camp, it doesn't show me any available partitions to install on. I have one partition called Macintosh HD. This is a clean install of Yosemite, not upgraded from a previous version on OS X. Any thoughts or help would be greatly appreciated.

    Has BCA partitioned your disk? You can check by looking at the output of the following command.

     

    sudo gpt -vv -r shwo /dev/disk0

     

    in OSX Terminal. You will need to enter your password to see the partition layout.

    BCA ha not been used on this Macbook before. It is a clean installation of Yosemite, and the install did all the partitioning automagically. Here is the output from this command.

     

    Michaels-MBP:~ bradleym$ sudo gpt -vv -r show /dev/disk0

    gpt show: /dev/disk0: mediasize=1000555581440; sectorsize=512; blocks=1954210120

    gpt show: /dev/disk0: PMBR at sector 0

    gpt show: /dev/disk0: Pri GPT at sector 1

    gpt show: /dev/disk0: Sec GPT at sector 1954210119

           start        size  index  contents

               0           1         PMBR

    Can you run BCA and start the process as documented in Set up a Windows partition on your Mac - Apple Support?
