This was a BIOS settings issue. In the BIOS of this Asus netbook I found a second setting, which also had to be set with "USB" as 1st boot device. When I found this setting, the 'Boot Settings' dialog box had the following categories: "Boot Device Priority". "Hard Disk Drives": It was necessary to additionally set "USB" as 1st boot device within the "Hard Disk Drives" category. In here its default settings were: "HDD" "USB".
