    I did not know that modifying the partitions when you have a bootcamp partition setup can screw it up. It did.

    I tried some different things I found online, but I think I am making it worse. At one point the drive showed back up when holding down alt restarting, but when I selected it I got a error that said "Non-system disk." Now windows doesnt even show up though.

    I deleted the partition I created in disk utility.

    How can I get bootcamp to show back up to boot windows

    I currently do not see the bootcamp option when holding down alt at startup.

    Backup what you can and reinstall. A pain, but at this point in time you're only going to make matters worse. The only way to modify a Boot Camp partition without destroying the Windows boot sector or maybe even OS X is to use third party software. WinClone for copying the Boot Camp partition and Paragon software CampTune for re-sizing it.

    I ended up having to save all his files from the partition, remove it, and start over with a new version of Windows.

    My brother has no clue how to maintain a computer and he had hundreds of copies of one file and important files saved in some random folder I couldn't find. A mess. Took forever.
