SSD not shown to install OS on

[Evo13]

I was trying to do a clean install of Yosemite and I erased my content off my SSD through disk utility and now when I try to install the OS, it does not show my SSD as an option to install it onto.

Perhaps you made it non-bootable in some way, does it show in Disk Utility? Can you re-partition it to recreate the Macintosh drive to install it on and then see if the installer sees it?

As a general rule, unless you have an issue to resolve, it isn't necessary to erase content before a routine OS upgrade.

It shows Samsung SSD but nothing underneath of it, I can see a partition but I can not run it. I wanted to clean install just so I can clean some stuff up.

Will it let you repartition it?

Will it let you repartition it?

No it will not let me.

What are you booted from while trying to do this?

You need to boot from something other than the SSD, and in Disk Util select the SSD brand name at the very top and then go to the erase tab and erase the entire drive. That should wipe the core storage volume you still have on there from the previous Yosemite install.

No it will not let me.

I ran disk verifcation and got this:

Try selecting the SSD and hitting "Erase". Make the name "Macintosh HD" or something else if you like and ensure the format is "Mac OS Extended (Journaled)".

Sorry for not responding, but the hard drive was locked and I had to erase the disk through terminal. Got it to work, just not enjoying Yosemite....
