Unable to delete the core storage logical volume gruop
MacBook Pro with Retina display, OS X Mavericks (10.9.3), 16GB USB
Have you tried starting up in Recovery Mode and erasing the disk from there?
Do you have FileVault enabled? If so, you need to turn it off and try again.
tried it. still same
I did not turn on firevault
Does anyone have ANY idea of how to fix this? I have the same problem - dogging me for 2 days. And cannot find the answer in these boards.
Thanks
