Hi all,
Unfortunately, I had to load my backup since the system would not work anymore because of a botched upgrade.
The good news is that the backup system is restored and running. The bad news is that I no longer can pick which OS I want my computer to boot with. I used to have at the Picker 2 icons, for macOS and for Windows. Now I have one for macOS but the icon where Windows was previously now reads NO NAME. When executed, I get a black screen instead of Windows.
How do I fix it and what is the best way to restore the Picker?
