    Hello everyone,

    I wanted to re-install my MacBook, so I erased the HD. but, when I want to reinstall the OS there is a notice that I need to connect to computer to power. the problem is that there is only one USC-C and I can't use it for power because I use it for the bootable USB. the recovery partition was erased when I erased the HD. there is any option to force install?

    Thanks!

    OK, I’ve solved it...
    I took an external HD and installed on it macOS using my iMac. Then, I copied the installation file from the bootable USB to the external HD (while running the OS on it).

    I turned off the iMac and connected the external HD to the MacBook. I turned on the MacBook while holding option key and choose the operating system partition (not the install partition). After the OS loaded I started the install and it worked:cool:
