KDE on Ubuntu causes issues during installation alongside macOS
You're facing a tricky setup situation. The EFI partition is already full with macOS's bootloader, and trying to install GRUB or KDE Neon there will likely fail. You can't resize /dev/sda1 without removing the existing macOS installation on /dev/sda2. Consider these options:
- Check if you can safely unmount /dev/sda2 and move macOS files there temporarily.
- Use a different partition for macOS (e.g., /dev/sda3) to avoid conflicts.
- If possible, create a separate EFI partition for KDE Neon and boot from that instead.
- Consult your system's documentation or support team for further guidance.
I had to rely on another solution to handle the mac EFI bootloader. In this situation, you probably don't require a dedicated boot partition, but it's wise to review the documentation first. You might want to use rEFInd to swap out the mac boot loader and enable Linux booting from your partition. Some important points are that rEFInd has certain issues—it sometimes retains old installation data (I've seen this with multiple distros) and deleting it can be tricky. Removing it after installation is difficult because you'd need to reinstall macOS to replace it. According to the creator's site, it remains in a beta phase. You can still use the default mac loader by pressing the designated key (the option key, as you remember). The positive side is that you can customize its look; I prefer a simple theme that works in both light and dark modes. Others may have successfully dual-booted using different tools or methods that simplified setup.
You already have a triple-boot system. The issue isn’t starting into Linux but installing it. The installer fails because GRUB can’t be placed on the correct device, either /dev/sda or /dev/sda1.
