On an older Lenovo S205 on which I never have managed to get Debian running, I did a netinstall of debian-bullseye-DI-alpha2-amd64-netinst.iso
grub dummy failed, but the boot process terminates with the grub> prompt. I tried the ls command: grub> ls (proc) (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,pt1) and I am able to boot manually by typing in grub commands: grub> root=(hd0,gpt2) grub> linux /vmlinuz root=dev/sda2 grub> initrd /initrd.img grub> boot The boot now proceeds, but the stream of messages terminates with the line: IPV6: ADDRCONF(NETDEV_CHANGE): enp2so: link becomes ready and the GUI interface does not start. However, ALT-F1 brings up a terminal with a login prompt, and I am able to log into the system. Curiously, the "shutdown" command is not recognized. The netinstall used a approx mirror here in my LAN. I did an expert install, but I allowed the installer to auto-configure the network. I am not using IPV6; the LAN gateway address is 192.168.1.1. Inasmuch as I used the approx mirror, re-installation would be easy, if that is the easiest way to resolve the difficulty. RLH
