Help! Wiping and Starting Over: Disk Utility options grayed out!

[mechanicalelf]

New Mac user, freaking out. Literally all buttons are grayed out on DU after a Command + R on Restart. I'm trying to follow another threads instructions on how to wipe and start over after not being allowed back HALF of my HDD space was set aside for W8.1 (I mistakingly [no one warns of this!] partitioned my HDD before using Bootcamp to make a bootable USB... I just wanted to play Steam games)... Now it's just phantom "Free Space". Right now my brand new MacBook is nearly useless and I have no way of fixing it. HELP!

Did you make a full disk backup before messing around with the partitions?

No, and I don't care to. I can start from scratch. It's only a few days old. I wont really loose anything. And I don't have an external HD big enough (32G or something, and my flash drive is 16G)

Now, I just want to wipe and restart from scratch. I know I screwed up. It sucks. BUT it wont LET me do this. Do I need to post a screenshot? Basically, when using Disk Utility from the cmd+r on restart (and on regular os) all options, literally everything inside the Partition tab, is grayed out and unselectible. Wth

You need to revert you drive from CoreStorage back to normal.

It goes something like this in terminal

see your disks by typing into terminal

diskutil list

...Mine was disk1....

diskutil cs revert disk1

AWESOME I think this will work--before I do this though--which do I want to use, disk1 or disk0?

I had this problem too and went through the normal Boot Camp procedure for both install and uninstall. I ended up deleting the corestorage volume and reinstalling.

Someone suggested that to me, but I had done another method just beforehand. Glad to know there are solutions. Cheers

I know I'm a bit late, but was it disk1?

I'm not sure! I ended up doing a different method from that reddit response. This was sure to work I'm certain though. Thanks for the help anyhow!

Some guys, even on here insist on using the UUID which is a big long number like "4928D289-899F-439C-727B", it should however do the same thing.

In the end, was the result turning off core storage (and not reformatting your hard drive?)

Yes, it was core storage change. Although I didn't mind if I had to, I am glad I didn't have to reformat. Thanks!

From his screenshot, yes it would be disk1.
