My MacBook pro mid 2012 was having macos 10.10 but system files have been deleted by mistake. Tried to reinstall OS X by disk Utility but login with iCloud was down. Last solution I did is to bring it to factory reset by global installation and it already downloaded macos 10.7 (lion) now I see (an error occurred while preparing installation. Try running this application again).
Is there any solution for this issue to complete installation?
How can I do bootable usb with disk utility or by windows 10 to install fresh copy of OS X? (Recovery mode)
Note: I have no time backup drive.
Please let me know how this issue can be resolved asap. Thank you!
