Erased Macintosh HD disk, flashing question mark start up and recovery keys don’t work!
I erased my Macintosh HD disk on my 2015 MacBook Pro. I wanted to wipe it. I’ve backed up and deleted most of the contents onto a hard drive. When I try to start it up it has a flashing question mark on a file picture and the apple support website. I’ve tried many recovery keys and non of them are working. Really hoping I don’t have to bring this into someone because I cannot afford it. If anyone else has some guidance I appreciate it!!
