[QUOTE="MacInWin, post: 1811415, member: 396914"] Welcome to the forum. The problem seems to be that your boot files on the drive are missing or damaged. That's why it won't boot. Sorry, but I'm not sure what that means. Do you have a screen shot of Disk Utility so you can be more specific? In upgrading to Mojave, your drive was reformatted to APFS instead of HFS+ format. You can read a bit about that here: [url]https://support.apple.com/en-us/HT208496[/url] The article is about formatting a drive in APFS, but shows how the new Container/Volume approach is managed. Copy of what? Mojave? If you tried to erase the entire SSD, you can't if you are booted from the Recovery partition as it includes the boot drive. You should be able to erase/format a volume in the container, as described in the article I linked, when booted from Recovery, but not the Recovery volume. So read that article and see if there is something there for you. Also this one about reinstalling the OS from the Internet: [url]https://support.apple.com/en-us/HT201314[/url] [/QUOTE]
