Restore CD shows "Authentication error" on a Sony Vaio laptop

Restore

I have tried urbackup_restore_2.3.0.iso, but it fails to load at an earlier stage.
I see messages about the discovered USB devices, then there is a long delay, a minute or two.
And then it shows a “BOOT FAILED!” message, like this one: Restore CD 2.3.0 beta
