Maining EndevourOS

Removing Windows From EOS Partition

  1. Install GParted:
sudo pacman -S gparted
  1. Open GParted:
sudo gparted

  1. Locate the EndeavourOS partitions — the ones you should not touch. These usually include:

    • / (root)
    • efi/
    • Any other partitions you’ve set up, like /home, /swap, /tmp

  2. After identifying those, find the Windows partitions and delete them:

    • Right-click the Windows partition > Delete
    • You’ll now see unallocated space.
    • Confirm everything looks correct, then click the check mark (✓) at the top to apply the changes.

Expanding Your EndeavourOS Partition

Now that you’ve got unallocated space, you probably want to expand your EndeavourOS partition (e.g. /, /home) to use that space.

  1. Right-click the partition you want to expand > Resize/Move
  2. A window will pop up. Slide the edge to increase the partition size or manually enter the new size.

Having Unallocated Space on the Left

[!IMPORTANT] GParted can’t move partitions to the left if they’re mounted. That means if the unallocated space is on the left, and you want to grow your / partition into it, you’ll need to use a live boot environment where the system partition isn’t mounted.

[!CAUTION] Note on Boot Issues. This action could mess up your boot loader. I personally did all of these steps and my system booted fine afterward. But just so you know — this is not guaranteed, so in case anything breaks, you’ll have to search for solutions online. (I don’t have a fix for that kind of issue at the moment.)

Create a Boot Stick

  1. Download the EndeavourOS ISO from the official website.
  2. Insert your flash drive.
  3. Create the boot stick:
sudo dd if=EndeavourOS.iso of=/dev/sdX bs=4M status=progress && sync

Replace /dev/sdX with the correct disk (not a partition like /dev/sdX1).

[!CAUTION] This will wipe everything on the flash drive, so back it up first if there is value data for you in it.

Use GParted from the Live Boot

  1. Boot into the flash drive.
  2. Open a terminal and install GParted (if not already there):
sudo pacman -S gparted
  1. Launch GParted:
sudo gparted

  1. Right-click your EndeavourOS partition > Resize/Move.

  2. A window will pop up. Slide the edge to increase the partition size or manually enter the new size. This time, you’ll be able to move/slide the partition because it’s not mounted.

  3. Click the check mark to apply the changes. A warning will pop up — read it carefully.

Done

You now have the best OS as your main and only system.
