    So I have a macbook pro late 2011 and I had a 70 Gb storage partition running windows 7. Ever since I installed OS X EL Capitan, I have ben unable to startup my mac to windows. I go on the startup screen and hold down the option key and nothing happens. I have looked at the system report and it shows the partitioned 70GB and their content says Microsoft Basic Data. I have also looked at previous threads on these forums and as a result I have downloaded "gdisk" and ran the "sudo gdisk -l /dev/disk0" and received the following results;

    GPT fdisk (gdisk) version 1.0.1

    I'm thinking you need to change the "type" that the windows data is cause it's obviously there.

    In windows and OS X you need to select the same operating system in the boot camp panel. But since you can't get into it you'll need to fix it first:
    I would update your OS X as best as possible. Then try to boot into windows recovery to try to repair it.

    I think the problem is the compatibility of El Capitan and windows 7. You may need to upgrade to 8,8.1, or 10
