MacBook Air '17 will not boot up normally/won't install Mac OS
I bought a new macbook and was clearing my old macbook air 2017 completely.
I went into recovery mode and erased everything on the disk drives. Now the macbook air starts up with black screen and blinking folder with a question mark.
I've looked up several remedies but none of them have worked.
I tried to reinstall mac os from the recovery menu several times but it says "an error occurred while preparing the installation" and I've also tried re-erasing the drives but it says "an error has occurred. could not be erased"
It's also not letting me install my time machine backup i put on my new macbook
Does anyone else have this problem or know a solution? Thanks!!
MacBook Air 13″, macOS 10.15
