| Good morning Roland, I’ve installed and reinstalled several times this morning, not using the Calamares installer, but rather using the Debian installers. All “successful” installs (meaning, boots to Debian after install) were done with the regular (text) installer. Here are notes: ISO Downloaded: Boot Mode: UEFI (secure boot enabled) Installer: Graphical Debian Installer Attempt 1 Result: Mouse and trackpad don’t work on the first screen (Select a language). Exited installation. Installer: Debian Installer (text) Result: Keyboard doesn’t work on first screen (Select a language) (Exited installation) Attempt 2 Installer: Debian Installer with external keyboard attached Result: Detect Network Hardware reports following missing: * ath10k/pre-cal-pci-0000:02:00.0.bin * ath10k/cal-pci-0000:02:00.0.bin Note that I’m using the ISO that includes non-free firmware Configure the Network: Connecting with wifi (Qualcomm Atheros QCA6174) reports that DHCP server can’t be contacted (chose do not configure at this time) Partition disks: Manually (1GB EFI, 100 GB /, 16GB swap, remainder /home) Configure the package manager: Doesn’t deterct netwok, so not using network mirror Installation complete No entries in UEFI boot menu Attempt 3 Repeat above, but when I got to partitioning, I chose Guided Partitioning - use entire disk This worked, restarted and got to the GRUB boot menu, and goes on to load OS However (read on): I can then connect to my Wifi, so I can add official sources to my sources.list Add Debian sources to sources.list and then sudo apt update && sudo apt upgrade -y Then things become unpredictable. First, time I rebooted straight into the Dell SupportAssist diagnostics, and found that I lost Debian entry from my UEFI boot menu Re-installed, and tried again, this time after restarting after the install, my keyboard and trackpad no longer work. Other info: As said before, no problems installing RHEL (and clones), Ubuntu, Pop, Fedora, or Manjaro. It is just Debian (and incidentally Linux Mint Debian Edition) that’s not cooperative. I’ve given up for this morning, and just installed Rocky Linux 9 on the computer with zero issues. If you have other ideas that you want me to try, I’m happy to do so some morning this week Thanks!
