how to "sudo zypper install systemd" after uninstall on dual boot system


Dear Reader,

I have several questions pertaining to my interests in computing.

1.) I had the idea that systemd would stay populated in the RAM until a restart on OpenSUSE 15. Due to errors I was seeing, I tried to uninstall and was going to reinstall immediately. Unfortunately, I hit a black screen (likely when Xorg(?) failed?) and upon restart I no longer boot properly. Leap logos up, but then stuck at a cursor, with seemingly no action from user input. Grub boots. Windows 7 boots. I see that with the installation media I would be able to restore or reinstall systemd. I don't have the media instantly, and would like to learn more about my system anyway.

The truth here is: I am having trouble booting to a terminal linux from where I would:

Code:
sudo zypper install systemd
and the problem would be solved.

What are the boot parameters for opensuse 15, I believe it is kernel 4.12.. to boot into recovery/repair/or just a terminal?

2.) I am interested in android devices as well. I would like to look into the course requirements for computer science/software engineering but then also the syllabi for stated courses. I can learn better with a little formal guidance. Currently I have rooted, recovered, custom rommed, and updated the kernel on several phones. I have never built these pieces myself though. Extracting an archive? Edit archive? Recreate? Etc? Are these even the correct questions?

This link might be good for someone with a little more experience:

I have formal education in visual basic through MS OFFICE if that will help you to help me. I would like to learn to write an algorithm.

3.)I made a folder in windows and tried renaming it to ".", for whatever reason.., and I was not allowed, I then tried renaming it to ".." and it said the file was "too large". It's an empty folder thats being recognized as too large due to a renaming. This doesn't doesn't make any sense to me.

Sincerely.

Have you considered booting from USB media using a rescue image, mount and chroot your opensuse root, and from there install systemd?

What I am finding to be easiest right now, granted the condition of no install media is; key combination to open terminal: "cntrl + alt + f2" at my malfunctioning startup. I do not have a repository with the correct systemd. Anybody with options? I may have to search how to add install media as a repository. Does anyone have a list of the correct functioning repo's from SUSE?

I seriously doubt you would ever be able to get zypper to uninstall systemd without uninstalling so much else depending on it that any effort to rescue it would be totally wasted. Too much depends on systemd.

If your PC has network access, then you don't need installation media to do an installation, repair or otherwise, if you still have a Grub menu that works. All you need are the initrd and linux from http://download.opensuse.org/distrib...x86_64/loader/ someplace grub can find them, and either a grub stanza added to load them, or to load them manually from the grub> command line. I do virtually all my installations using this method. https://en.opensuse.org/SDB:Network_installation has the idea, though it may be lacking in some detail.
