Thank you for the ideas. The manufacture date of this HP Pavillion Notebook 15-au123d was 07/01/2017. NetBSD is installed UEFI.
I tried `boot -2' but the startup stopped at the following. I don't know how to proceed. boot device: <unknown> root device: The machine works without any problem, including power-off shutdown, with Windows 10. I swapped out the harddisk that Win 10 was on with an SSD, onto which I installed NetBSD. Other than `/sbin/shutdown -p` not working (which however is fatal to my use of the machine as a remote workstation), things seem to be working well (with current, not under 9.2 STABLE).
