Have you tried reading the rescue section of the manual? https://www.debian.org/releases/stable/amd64/ch08s07.html.en After booting the rescue media, you must mount the Stretch root filesystem if the rescue startup didn't do that already for you. Figure out which one it must be using 'fdisk -l' or 'gdisk -l'. If it appears to be /dev/sda3, then do: mount -t -o rw auto /dev/sda3 /mnt If successful, the Stretch /etc/ will be found at /mnt/etc/. -- "The wise are known for their understanding, and pleasant words are persuasive."

If you had made a copy before your edit it would be a simple matter to rename it. :-( That said, that file is a plain text file. Any editor available in rescue mode can put it back once the Stretch / partition is mounted. Try nano first, which for most people is much more intuitive than traditional Linux editors like vi. Something to try first: append plymouth.enable=0 to the kernel cmdline for an otherwise normal boot. Also try appending a 3, which should block startup of the GUI login manager, but also should make normal ttys 1-6 available. -- "The wise are known for their understanding, and pleasant words are persuasive."

I tried that, but after I entered my /home password the boot continued and then stopped. After waiting fifteen minutes or so I concluded that the machine hanged. I tried using the recovery mode from GRUB, but that hahged the machine as well. I then tried rescue mode from the installation disk.

(check F7 and F8 too) I should have thought of that, but when I wrote my original post I was tired and frustrated. Thanks for the reminder. This morning I did as you suggested. Yes, ctrl-alt-F2 to F6 does open a console where I can log in one of them as my user and in another as root. So far I seem to be able to execute all the commands I need to or want to in both. For example, in my user I was able to run startx, which prodices a bluish hue screen with the Debian swirl. I can't go any further because I do not have a desktop environment yet. My next step is to install one and see what happens. Ctrl-alt-F7 and F8 open nothing, not surprising as F7 and above are normally reserved for graphical user interfaces (GUI), which I have not yet installed. Ctrl-alt-F1 shows the blank screen which appears at the end of the boot. I think the problem is that what appears on opening tty2 to tty5 should appear in tty1 but for some reason does not -- instead the blank screen. > >> As part of the boot it accepts my /home password, but I do not >> get the command line.

To > close the computer I have to use the power switch. oh, this doesn't sound good, but since you don't describe your keyboard or mouse type i'm not sure if you need to change something in the bios or what for them to show up. check the bios if you have settings that might help. use a different keyboard and/or mouse to check that something shows up. your X setup may need adjusting. check /var/log/Xorg.0.log and X*.log.old if you have no log files install rsyslog. > I can open it in recovery mode, and after I enter the root password I > can get the command line as root.
