I need to install an OS but I wiped the drive

Hi so I was trying to install Windows on my Mac and halfway through the mac just shuts off as I was installing Windows to use this as a main laptop for some time I was using the whole hard drive and I never created a drive I could boot the old os x off of

I have tried external windows 10 and ubuntu drives but I can not get an os to boot also the screen is just completely black upon opening the lid and powering on along with the keyboard backlight does not turn on and the apple logo on the back does not light up but when I plug some thing in to the usb ports I can see light on the device I plugged in showing drive activity and if I press caps lock on the internal keyboard the caps lock light will come on

I think you’ve got things switched about here … B, A, C is not the correct order you need to first fix A, then B then C.

What you describe here is a dead system not an OS issue so we need to fix it first (A), then you need to recover the OS (B) then you need to install it (C)


The system worked just fine till i tried to install Windows while installing Windows the computer crashed and now will not do anything

You’ll need to see if you can get the onboard diagnostics to run. Restart the system and press and hold the D key are you able to get to the diagnostics? If you can’t see the display shine a flash light through the Apple Logo are you able to see the screen at that point (it will be faint). If you do did you get an error code?

Reference: Mac startup key combinations

If you can’t get that far what is the color of the MagSafe connector Amber or Green?

They computer basically seems to not do anything at this point the fan will spin up but there is not even the normal startup chime.

And the magsafe connector is green I've left it on the chargeable night.


It sounds like your logic board has a problem. As its not even responding. At this point you'll need to open the system up and do a deep inspection of the logic board taking it out as well as cleaning the dust off using a soft paint brush and a can of can'ed air. Follow this guide MacBook Air 11" Mid 2012 Logic Board Replacement do you seen anything out of place or looks questionable?
