While trying to install virtual windows os in my mac os (macbook pro mid-2012), i think i ruined its system 😟 . I didn't even created a backup before trying to install it . What should i do to recover my original mac os ? i bought just a month ago 😟
MacBook, OS X El Capitan (10.11.3)
With no backup about the only thing you do now is to do an Internet Recovery to reinstall the original operating system once again. This will of course mean that you will lose everything on your Mac.
To restore OS X:
Install or Reinstall OS X from Scratch
Be sure you have backed up your files because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.
This should install the version of OS X that you had installed.
i think i ruined my new macbook :(
