Q: Can't remove the bootcamp disk!

Hello. First of all I own a Macbook Air 13-inch early 2015. Yesterday I've tried to install Windows 10 to my mac via bootcamp. In Windows' website I've downloaded the version of Windows 10 for my mac by usin a USB flashdrive. When I open the bootcamp it recognized the file but before or after that I never had to check off anything just had to continue the process. After hours my creating disk process was over but there wasn't anything about restarting my mac. After that I restarted my mac manually and nothing happened. When I check the disk ultility I can see a disk called "BOOTCAMP" but I can't erase it even when I click APPLE SSD media disk (which I believe the main disk or something) I press Partition and when I click on BOOTCAMP disk I can not press "-" to erase it. My bootcamp can't erase the disk as well. I've tried the /sbin/mount -uw / and sbin/fsck -fy but both of them didn't really help me at all. What can I do to erase that disk with 34gb? Thanks.

    I'm afraid you reformatted your OS X volume using the Windows formatter, thus destroying OS X. You will need to repartition and reformat the drive then install a fresh copy of OS X. You will accomplish this by using Network Restore:

     

    Clean Install of El Capitan on a New Disk

     

            Be sure you are connected to the Internet, preferably by Ethernet because it's faster than Wi-Fi.

     

    1. Restart the computer. Immediately after the chime hold down the Command-Option-R keys until a globe appears.
    2. The Utility Menu will appear in from 5-20 minutes. Be patient.
    3. Select Disk Utility and click on the Continue button.
    4. When Disk Utility loads select the drive (usually, the out-dented entry) from the side list.
    5. Click on the Partition tab in Disk Utility's main window. A panel will drop down.
    6. Set the partition scheme to GUID.
    7. Set the Format type to Mac OS Extended (Journaled.)
    8. Click on the Apply button, then click on the Done button when it activates.
    9. Quit Disk Utility and return to the Utility Menu.
    10. Select Reinstall OS X and click on the Continue button.

     

    This should install the version of OS X that was pre-installed when the computer was new.

    Hello. I've tried your method but even in the Utility Menu I couldn't erase the BOOTCAMP disk at all. No matter what I've tried it just sits there. I have reformatted my mac and there's basically nothing in it right now but the BOOTCAMP disk continues to exist.
