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.

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

    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.

    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.

    If you keep around a bootable rescue stick like System Rescue it has a boot menu entry that will boot the Linux installed on your machine. Once you do that you can run a command or two to reinstall the bootloader. You can search the net or whatever at leisure since it will work fully.

    Alternatively, if your system Linux is borked harder, you can boot the rescue Linux and use more advanced methods, depending on what’s wrong. The rescue Linux also has a graphical environment with browser if you need it.

    At the very least sometimes you can figure out what went wrong. It may not be much comfort if you lost your system but at least you learn what not to do in the future. Too many people just say “oh, it just broke” and leave it at that.

      I think I know what the issue was… I modified the grub.cfg file and ran grub2-mkconfig and I think it was saying it detected a Linux install at my root partition, but didn’t seem to recognize my /boot or /boot/efi partitions and I couldn’t figure out how to edit that via the grub cli. If that wasn’t the case, then that’s okay. I’ll make sure to teach myself a bit more about the bootloader before trying to edit it again
