Blinking Question (?) and HDD missing in Disk Utility after failed upgrade to OS Mojave
Hi, I attempted to upgrade from High Sierra OS to Mojave (or to Catalina) on a a Macbook 12 (2016).
The installation got interrupted and a message error showed up. Since then, it won't restart any longer and keeps displaying a blinking boxed ? symbol.
I've tried every option for recovery but HDD is missing in Disk Utility (theres is only a Disc Image and a sub item: macOS Base System of 2,01GB ).
I've tried everything possible and still no HDD is found.
Please Help!!!! (I am in Argentina and no Apple Service is available).
MacBook, macOS 10.15
