Q: Fusion drive fail, bootcamp partition works fine

I have a late 2012 mac mini i7 quad core processor with a 1 TB fusion drive that i put together. Yesterday, I was casualy using it when it started to freeze as slow down tremendously. I got fed up and had to do a hard reset. the loading bar got stuck on 3/4. So i tried a few commands in hope that it would just be a small hiccup. here is all that i have tried with no luck.

- Option+Controll+P+R to reset the nvram

- Option+ R (I think) to access disk utility to see if i could do a repair and i got a red ! saying it failed.

- Shift key to access safe boot. After many tries i finally got in using the guest account. my background from my desktop was still there along with my apps which tells me nothing has been deleted ( I forgot to mention that in disk utility i tried to erase the partition for the mac and was told it failed.)

-command + s and entered this phrase that i forgot. it was in a forum that i found and after i typed reboot and still nothing.

- I tried to re install the OS and it couldn't.

 

After all these attempts, i got into safe boot and tried to access disk utility and cant get in anymore because of something related to core storage. Windows side works perfectly fine.

 

PLEASE HELP!!!!!!!!!!!!!!!!!

    Greetings riverozacari,

     

    I understand from your post that you're having trouble starting up your Mac normally, but you have managed to start it up using safe mode. I can certainly understand why this would be a concern, and I'd like to provide you with some assistance.

     

    As a first step, I'd recommend that you back up your data using Time Machine if you're able to log into your user account with safe mode. This website gives an overview of how to complete a backup with Time Machine:

    If you're not able to log into your normal user account or if you encounter an issue creating a Time Machine backup, I'd like to suggest an alternative method that will allow you to access the data on your startup disk. This method is called target disk mode and allows you to share files between two Mac computers with FireWire or Thunderbolt ports. Take a look at the following website for requirements and instructions on using this method:

    Once you feel that your data is secure and backed up, I would recommend that you erase your startup disk and reinstall OS X to see if the problem persists. You'll need to follow these instructions to erase the disk and reinstall OS X on your Mac:

     

    If you're reinstalling for other reasons

    OS X can be installed over the same version or earlier version of OS X, without removing your data. You don’t need to remove or disable the existing system first.

    1. Start up from OS X Recovery by holding Command-R immediately after turning on or restarting your Mac. Release the keys when you see the Apple logo. Startup is complete when you see the OS X Utilities window.
       
    2. If you do want to erase your disk before reinstalling OS X, open Disk Utility from the OS X Utilities window, then use Disk Utility to erase the disk. Quit Disk Utility when done. 
      Erasing the disk isn't necessary unless you're transferring your Mac to a new owner, partitioning your disk for use with Boot Camp, or attempting to resolve an issue that Disk Utility can't repair
       
    3. Choose Reinstall OS X from the OS X Utilities window, then follow the onscreen instructions.
      This installs the latest version of OS X that was previously installed on your Mac.

    Once you're finished reinstalling OS X, you can restore from your Time Machine backup or use an external hard drive to manually migrate any data that you saved to another Mac with target disk mode. 

     

    Cheers!
