I have a Macbook Pro. I installed Ubuntu and wiped all the partitions in the process (fit of rage and getting angry at OS X)
someone told me to "clear PVRAM by holding Option+command+R+P" I did, this, now not even my ubuntu loads up.
when I turn on the computer i get a white screen with a flashing folder with a question mark in the middle.
when I boot by holding the option key, all I get is a white screen with a mouse pointer which i can move around.
I have created a bootable USB drive using instructions from the below, although unable to boot from USB. http://pureinfotech.com/make-bootable-usb-mac-os-x-windows/
How do I go back to OS X (or even Ubuntu, so I can at least have a usable machine)
This question is close to my situation, but I exhausted the things that fix that issue:
- My bootable USB doesn't work (so I need Mac OS to make a new one
- I cannot get to the recovery tool or the Disk Utility. I've clearly deleted the recovery HD so Command + R fails to load a now missing recovery tool.
Ubuntu was working fine before i cleared PVRAM. Even with Ubuntu, when I started with Command+R, I get taken to a white screen with a mouse on the screen that I can move. This, I would say, rules out HDD issue (unless clearing PVRAM can destroy your HDD)
Once clearing PVRAM is when I get the folder with the question mark, and Ubuntu now doesn't even load.
