Each of those OSs were on their own SSDs. I went from a 128SSD - with Windows installed, to adding a 256 installing Debian. Years later I - split the Debian SSD into two parts - installing Manjaro on my new slice. - Since my last update I have been playing around with Manjaro and having - made my i3 keybindings for Kwin I've been pretty happy. But then I - started breaking things.</p> - <h3>Break stuff</h3> - <p>I broke my Manjaro by updating my Debian (apparently). To be honest - this is the one part I don't fully understand <i>why</i> it happened. - From what I could find online I didn't setup my system to handle two - separate Linux OS installs. But I was no longer able to boot directly - into Manjaro without using the initramfs failover boot option. I only - updated my Debian install because I was debugging something on my work - install, which both run Debian/sid. (Otherwise I would've used my - server which runs Debian/Stable). But considering I hadn't had any - need to boot back into Debian I decided to just get rid of it!</p> - <h3>GParted, Grub, Gotchas!</h3> - <p>I went in knowing I'd have to fix my Grub since I'd be - removing Debian, which was the OS that I configured when I first - dualbooted the machine, so I assumed they were linked somehow and I would - need to reinstall it. The process I followed was:</p> - <ul> - <li>Create a GParted Live USB</li> - <li>Launch GParted reconfigure my partitions</li> - <li>Open the terminal in the live USB and reinstall Grub</li> - </ul>The 3rd point being a bit of a "rest of the owl" I - wasn't sure what to expect. GParted thankfully warns you - "you're probably going to break stuff see our FAQ" which - had a section on reinstalling grub. Reading that the 3rd part became: - <ul> - <li>mount the linux OS</li> - <li>bind the live dirs that are needed: <code class='inline'>/dir /sys - /proc</code></li> - <li>chroot into the mounted folder</li> - <li>run <code class='inline'>grub-install <device></code></li> - </ul>But what I failed to realize (stupidly in hindsight) was the - "device" is the Master Boot Record (MBR) device. So in my case - Windows or <code class="inline">/dev/sdb</code>. I had assumed it was the - device of the linux install so I tried that and got notified my EFI boot - directory didn't look like an EFI partition... and from here it was - rabbit holes. - <h3>Where is my EFI partition?</h3> - <p>I have a fairly old Windows 7 install that has been upgraded to - Windows 10 during this whole journey. I've been meaning to reinstall - it (on a larger drive). But rather than having a few partitions on my - drive (typically having a boot partition) I just have the one (and a - recovery partition). Its marked as boot, and even mounted to <code class= - 'inline'>/boot/efi</code> I found when I was able to boot into Manjaro - again. But it made no sense to me. If I needed an EFI partition, why was - my efi pointed to the root of my Windows C drive? The rabbit hole - consisted of:</p> - <ul> - <li>Creating a 200MB Fat32 Boot partition</li> - <li>Mounting that as my efi-directory</li> - <li>Reinstalling grub (again on my Linux device)</li> - <li>Eventually getting it to boot straight into Manjaro</li> - <li>Modifying my <code class='inline'>/etc/fstab</code> to mount my - boot/efi to the new partition (oops)</li> - <li>Repeating the above steps 5 times hoping something would be - different</li> - <li>Eventually finding in a forum that grub should be on the - MBR...</li> - </ul> - <h3>The Fix and Final Steps</h3> - <p>The fix was to basically follow the steps above but use the MBR:</p> - <ul> - <li>Boot GParted Live USB</li> - <li>Properly configure any partitions (this case delete the - "EFI" partition)</li> - <li>Mount the linux device</li> - <li>Bind the necessary live dirs to the linux mount</li> - <li>Run grub-install to the MBR device</li> - <li>Reboot</li> - </ul>It was that misunderstanding about the MBR that sent me on a path, - but now I at least feel semi-confident in changing around my OSs knowing - how to fix Grub. But what bout the Fstab? - <p>Like all true movie monsters, my stupidity came back for the final - scare. I booted into Manjaro, from Grub! to have it crash on me. It - couldn't mount one of the devices! The deleted partition! I was in - the recover shell and was able to modify the Fstab to point back to the - correct boot/efi device. (Thankfully I was familiar with Fstab to begin - with). But editing two files in a super-low-res terminal is not my idea - of fun (okay, maybe it is).</p> - <h3>Conclusion</h3> - <p>One of my new years resolutions was to learn more about my system. So - lighting a fire I had to put out was a great way to get some more - knowledge on maintence for grub/dualbooting.</p> - </article> - <div id='footer'> - <i>January 5, 2021</i> - </div> - <div id='copyright'> - © 2023 senders dot io - <a rel="license external noopener noreferrer" - target="_blank" - href="https://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA - 4.0</a> unless otherwise noted. - </div> - </div> -</body> -</html> |
