I was installing windows on my mac. But during mbr to gpt conversion, I just formatted the entire disk into gpt and now my mac is having only windows. I need OS X also along with that. How to do it? Need assistance.
MacBook Pro, Windows 8
What year is your MacBook Pro, and what operating system was on it before you chose to plunge it into total darkness?
What happens if you boot it with the option+command+R keys held down?
model is of mid 2012. It was running on mavericks and now its not in darkness. Instead it is running on windows 8.1.
If I boot with op+cmd+R, it will ask for network recovery. But if I select the wifi network, it will stop at a screen in which a globe is rotating and time is running at bottom.
Plug in an Ethernet cable, and see if just command+R will boot you into Recovery, so you can reinstall Mavericks. You will have to use Utilities to reformat that boot drive as OS X HFS+ Extended, options as GUID. Once you get Mavericks reinstalled, and fully updated, then use its Boot Camp to reinstall Windows 8.1.
If for any reason the boot from Recovery does not work, then you will have to perform the boot into Internet Recovery that I mentioned in the previous post. That will not fetch Mavericks, but the OS X release (Lion) that originally shipped with that model MBP. If you had ever downloaded Mavericks from the OS X App Store, then you should be able to redownload, and update to Mavericks.
Well, if you need windows.
-- You can set up you mac to dual boot windows and os x.
-- You can install virtual box app and run windows in virtual box.
Look on your router. Are the lights blinking fast? Hence something is being downloaded.
I'd try a cable connect to your router.
