Restarted, F12, picked out HDD from bootlist, booted, got into Debian installer. Does a few steps (language etc). Gets stuck at 'No common CD-ROM drive was detected'. Ideas?I suggest writing the installer iso to a USB stick, and booting from that to install. Win32diskimager should be fine for that purpose. If you still have difficulty, please also say exactly which iso image. Good luck.
Thank you for this. Followed your suggestion using debian-10.6.0-amd64-DVD-1.iso The whole installation seemed to run to completion, but:1. When laptop rebooted with external HDD unplugged (indeed nothing in either USB socket) Windows-10 booted up (expected behaviour).
2. When laptop rebooted with external HDD plugged in, and F12 pressed repeatedly, went into one-time boot showing both 'Debian' and 'Windows Boot Manager' (expected behaviour). Unexpected behaviour was that, on taking 'Debian' option, screen showed (in tiny letters)
'Press F1 key to retry boot.
Press F2 key to reboot into setup.
Press F5 key to run onboard diagnostics.'
Expected behaviour was to boot into Debian.
Best regards
