Don't have startup disk in recovery mode

Today I received mac mini and I wanted to deploy the image. Except, I don’t have any booting disks that are listed in the recovery partition. But the mac boots normally. So, I get an error message that says no startup disk is found. How is this possible? And how can it be fixed?

Boot the Mac normally and set the startup disk manually again. after them try with recovery again and check if you can see the startup disk.
