    Hey everyone! I'm starting to stress out a bit because at this point my Mac is totally unusable. I had OS X 10.11 installed and Windows 10 via boot camp. I installed the El Cap PB 5 but my Mac shut down during the update so it couldn't boot anymore. I booted up the recovery and decided to erase my MacBook Air sdd as I didn't mind doing a clean install. This was very hard to do as the drive was somehow encrypted, but eventually via Internet Recovery I managed to reinstall OS X.

    The problem however was that I discovered after OS X booted it only had 67 GB available from the 128GB SSD in my MacBook. So I opened up recovery again and when I used terminal with diskutil list I saw that somehow my whole drive is messed up. It shows 15 (!!) disks. I tried but I can't get it to merge again to one single drive of 128GB. I attached photos of what is shown. I need this Mac to work again as soon as possible and maybe I have not been smart in my decision to format the hard drive but I thought a clean install would do my Mac some good: unfortunately it turned out to bring a whole lot more problems. I have absolutely no clue how to solve this. Help would be greatly appreciated!

    I had a member returned air like this and I ended up giving up with disk utility and using an Ubuntu USB stick to boot and then partition and format the drive. Once I'd done that I used internet recovery to put OS X back on.

    Don't need to worry about that so many disks named "untitled", and the sum of all those disks would never be equal to the space you lose in this case.

    El Capitan has serious issue on removing Windows partitions, currently. I have encountered this many times, and none of them end up with partition table fixed. Instead, I need to backup Mac partition, format the whole disk, and bring Mac OS X El Capitan back from backup.
