I recently made a post discussing my move to Linux on Fedora, and it’s been going great. But today I think I have now become truly part of this community. I ran a command that borked my bootloader and had to do a fresh install. Learned my lesson with modifying the bootloader without first doing thorough investigation lol.
Fortunately I kept my /home on its own partition, so this shouldn’t be too bad to get back up and running as desired.

    Just wait until you learn the powers of chroot :)

      Few days ago I downgraded glibc(I’m dumdum) because it was recommended in a reddit thread for a problem I was having. I couldn’t even chroot. Fortunately I could update with pacman --root

    Borked your bootloader already? You’re a true Linux user lol. You’ll eventually learn to not do that (and back up regularly).

    Good choice with Fedora! I love dnf and the choices Fedora makes overall.

      OP should just know that TimeShift doesn’t work on Fedora Workstation without some tinkering.

    That’s where you’re wrong :)

      You’re right. I spent a few hours trying to fix it before giving up and determined that reinstalling would be quicker lol

    I’ve messed up my system so many times over the years that now I think I secretly get excited when it accidentally happens. Maybe I’m a masochist, but I actually enjoy trying to understand what went wrong. A USB stick with a light weight Linux distro and chroot you can usually get back in there and look around at the damage.

    Friendo, I think once you understand exactly what an OS is, you’ll have fewer problems. An OS is just a layer on top of hardware with a lot of scripts and tools that enable that hardware to do things like move files, show graphics, and send audio in a desktop environment. Never issue a root or sudo command unless you understand exactly what it’s doing. Following this one simple rule will save you a lot of trouble, same as any Windows machine.

      And a lot of configuration, or so I thought? I’m investing heavily but I’m scared for my investments :-)

      Another Linux noob here, after a couple of Linux servers (Tenfingers, Lemmy) switched over (finally) my main PC, or well kids got the gaming machine and I’m on a Mint ThinkPad now :-) and a backup think centre tiny if the Lemmy server bails out.

      I have this little windows box to print stuff (I didn’t know I hated printers) and every time I use it I’m so happy I don’t need windows in my personal life anymore…

      Cheers and welcome OP!

          Except that I’m jumping ship to Linux fully, I’m thinking a lot about hardware failure, not the data but say the mobo, so maybe that’s curious. Seemed you were knowledgeable about those things, or I’m explaining very badly.

          Cheers

      This is reasonably valid. I think Windows makes it a bit harder to do real damage to your system, so I’m used to that. I also have borked installs in VMs before, but that’s never mattered because spinning up a new one takes no time. Definitely a valuable lesson to do more research before running commands, especially as sudo

      Also, once your install is in a state you like, create a backup with CloneZilla.

        Nah. This is old school thought. Use an immutable distro if this is your concern, and keep all your files on a NAS, or something else that can replay your files. Local images of your entire filesystem isn’t needed anymore.

            They are two different things.

            A Clone of an OS install is not needed anymore, for a jillion reasons.

            Personal files do not relate to that.

            Perhaps you don’t understand how these are intended to work?

                Heyha ! Read about dd on makeuseof after reading your post, to see how it works.

                Restoring from an image seems exactly what I was looking for as a full backup restore.

                However this kind of 1 command backup isn’t going to work on databases (mariadb, mysql…). How should I procede with my home directory where all my containers live and most of them having running databases?

                Does it work with logical volumes? Is it possible to copy evrything except /home of the logical volumes?

    In my first few weeks of linux I screwed up mounting a hard drive and my pc wouldn’t boot past grub. 4x different times I tried and each time I broke it. Then a year later I revisted mounting the drive and it went smoothly.

    When you get more advanced you can use a distro like System Rescue to fix your bootloader instead of having to reinstall everything

    Trial-and-error is a beautiful thing, isn’t it?

    t. Had to reinstall GNU/Linux several times through the course of months while trying new stuff and/or trying to improve the current ones.

    Keeping /home separate is a good call. I can also recommend backups to a different system. Also test those backups.

    Playing with things can be fun if that is what you enjoy. Being careful is good but the best way to avoid serious issues is being able to recover from the worst case.

      Why do you advocate for keeping /home separate?

      I personally don’t do it because the more partitions you have, the more often you need to fiddle around in GParted when one partition gets full. This is also why I use swap files instead of swap partitions

      As far as I can tell, unless you distro-hop, separating /home doesn’t have any advantages. Even then, sharing one /home directory between multiple desktop environments can cause some problems

      I agree with making and testing backups, though. My current strategy is to back everything up to a 4.2 TiB ZFS pool with daily snapshots on my LAN, and back up the most important data on that to the cloud

        I don’t think it is critical to keep /home separate but if you need to reinstall it is really nice. You can reset the OS without touching your data or user-level configs. Either for the same distro because you fiddled around and broke it or another one for distro-hopping. It also makes encrypting it easy, although full-disk encryption is getting so easy that it probably isn’t an issue. Good backups also mitigate this, although the recovery will be slower than just reinstalling while leaving your existing home there.

        To be honest I don’t actually keep home separate anymore. But that is mostly because I trust NixOS enough that I know I will never need to reinstall. I can always roll back or worst case install over top of the existing install from a live USB.

        Overall I would say that the cost of doing so is fairly small as well. Unless you are running a lot of system services data outside of /home is usually fairly limited. Although I agree that getting the partition sizes wrong can be frustrating.

    Sweet, welcome! :) I know the feeling. I just finished reinstalling Nobara after being dumb and goofing up patching. Then I tried to fix it and made the system totally unusable and I gave up.

    A while ago I jacked my grub config and decided to try to fix it manually. I managed to stumble through it and learned some stuff, though I am still fuzzy on some details.

    I mostly want to just use the computer without a lot of headache and both Mint and Nobara have been great for coding (various), electronics design, 3d modeling and printing, graphics, photo editing, and such.

      This is why I gave up on fixing it yesterday lol. I spent a few days setting it up, I didn’t wanna spend a few more days to try to figure out exactly what the issue was when I could just give in and then actually use it

        Totally valid! Theoretically with more experience it may be easier / faster to fix but…idk

        See this is why I keep /home on a separate partition (or drive in some cases). I can reinstall or switch distros anytime without worrying about all my files (they’re backed up, anyway but doing a restore is a pita).
