Screwed up new MX Linux on a dual boot, now what?

[Brickwizard]

and a ssd with MX Linux 25 KDE.

so you say your SSD has MX-25, but you don't like it, so in plain English this is what I would do if I am using the SSD for just one distribution, [this is for most Debian ones]

download a fresh ISO from an approved source
burn to DVD-r as a data disc at slow speed or write to USB as bootable ISO
boot the ISO/DVD to Live [test mode]
Using in live mode find in the menu [or may have to install from your repository] an app called discs and open it, look for the SSD and highlight, in the top bar right-hand side of the disc screen are 3 vertical dots, click on and select. And run format, THIS WILL COMPLETELY WIPE THE DISC, so make sure you get the right one,
when finished, power off [not restart] then install your new distribution in the usual way [don't partition the drive let the installer do it]

It's not that I don't like it - after all, I don't even know it. Sure, if I had installed a Linux myself, as I initially wanted to, I would've picked MX Linux 23, simply because I'm used to it.

But, since MX 25 was installed, I thought I might as well try it, particularly since it is now officially released and 23's days might be numbered, anyway. While I didn't mind sitting on Windows 7 until last summer, I wouldn't want to do the same thing with an outdated Linux, as Linux is now my main os and the one with which I go online. Also, Linux gets updated every day - whereas my Windows 7 was/is a WSUS Offline-NLite-installation that had never seen an official Windows update in its life.

So I think I'll keep it and see it as a nice way to get used to MX 25 while the laptop still runs MX 23.

I might still end up reinstalling MX Linux - from my freshly burned MX Linux 25 KDE DVD - but first I want to try and fix the existing installation nonetheless. On the one hand, to learn something, and hopefully get a tad more familiar with the terminal stuff (definitely not my world...), on the other, because I hate giving up so easily, and last but not least, because the repair guy scared me a bit, what with how complicated it would be to do that whole Uefi/grub/whatever stuff, and not ruin my Win 7 in the process. Then I read that MX is difficult with Dell AND nVidia, and it all sounded terribly difficult, even though both my new FrankenDell and my old nVidia card are practically antiques. Still, the old MX 23 DVD failed to install, no idea why. Best guess so far is it's not ahs.

it's ctrl alt f4.

Ah, yes! My apologies for misquoting the hotkey shortcut (ctrl alt F1 to F6; the terminal on F1 frequently is the graphical desktop). I use them all the time, yet still misquote them here repetitively.

The commands you can use on the text mode are the same in the terminal application of your graphical desktop - without any exception. Just like with the graphical terminal, you type exit to log out of it.

Thank you, I understand it so far as that I'm trying to change a surrounding while I'm in it.

So I'm clear to change what the guide calls step 2, that is make the changes to /etc/group.

But where would I do the

sudo mv home directory

? The moment I log in the system I'm in it?

Is there some kind of DOS in Linux? I mean, a command prompt somewhere before it even starts?

I've been to something similar when I changed the password to get in, via the "advanced MX Linux" - I guess it's the GRUB thing that does that. It was basically some sort of console. Would that be the "DOS"?


@APTI - The minute it involves a screwdriver, I'm out...

But the big computer does have two hard drives - the old hdd with Windows 7 on it, and a ssd with MX Linux 25 KDE.

I've attempted to install my old MX Linux 23 KDE DVD over it, but it failed. No idea why, it worked just fine on the laptop before it. I've now downloaded a new MX Linux 25 KDE and put it on a DVD, but haven't tried to reinstall yet. Still trying to fix it.

I mean, I like the option with the GRUB menu to choose between Linux and Win7, and I like that apparently, I can access the Win7 directories from Linux. And since Win7 is a closed system that will never see an update and will never even go online, it can't wreck much, can it?

10 minutes with screwdriver < 10 days of configure.

A mathematical formula you might want to learn. Far more stable and easy to do. Choice is yours of course. I just give the information.
