How to change grub themes in kali linux

To change the GRUB theme in **Kali Linux**, you will need to download a new GRUB theme and configure the GRUB bootloader to use it. Here’s a step-by-step guide to help you change your GRUB theme:

### Step-by-Step Instructions to Change GRUB Theme in Kali Linux

#### 1. **Download a New GRUB Theme**

You can find GRUB themes on websites such as:

- [Gnome-look.org (GRUB2 Themes)](https://www.gnome-look.org/browse?cat=108)

- [Pling](https://www.pling.com/browse/cat/108/)

Download a theme you like, which usually comes as a compressed file (`.zip`, `.tar.gz`, etc.).

#### 2. **Extract the Theme Files**

Extract the downloaded theme to a folder:

For `.zip` files:

```sh

unzip theme-name.zip

```

For `.tar.gz` files:

```sh

tar -xzf theme-name.tar.gz

```

Make sure the extracted folder contains a `theme.txt` file (this is a configuration file that GRUB will use).

#### 3. **Move the Theme to the GRUB Directory**

Copy the extracted theme folder to the GRUB themes directory, typically `/boot/grub/themes/`:

1. **Open a Terminal** and run:

   ```sh

   sudo mkdir -p /boot/grub/themes

   sudo cp -r theme-folder-name /boot/grub/themes/

   ```

   Replace `theme-folder-name` with the actual name of the theme folder you extracted.

#### 4. **Edit the GRUB Configuration File**

Now, you need to tell GRUB to use the new theme by editing the GRUB configuration file:

1. **Open the GRUB configuration file in a text editor:**

   ```sh

   sudo nano /etc/default/grub

   ```

2. **Add or Modify the GRUB Theme Line:**

   Find or add the following line to specify the path to the theme:

   ```sh

   GRUB_THEME="/boot/grub/themes/theme-folder-name/theme.txt"

   ```

   Make sure to replace `theme-folder-name` with the name of the folder you copied earlier.

#### 5. **Update GRUB Configuration**

After editing the configuration file, you need to update GRUB to apply the changes:

1. **Run the following command to update GRUB:**

   ```sh

   sudo update-grub

   ```

2. **Check for Errors:**

   Make sure there are no errors in the output. If there are, double-check the path to your theme.

#### 6. **Reboot to See the New GRUB Theme**

Reboot your system to see the new GRUB theme:

```sh

sudo reboot

```

During boot, the new theme should be displayed.

### Troubleshooting Tips

- **Check Permissions:** Ensure that the theme files have the correct permissions and are readable by GRUB.

- **Ensure Compatibility:** Some themes may not be fully compatible with all resolutions or versions of GRUB. Choose a theme that matches your system configuration.

- **Fallback to Default Theme:** If you encounter any issues and cannot boot properly, you can access the GRUB menu and edit the boot parameters to remove the theme line or boot into a recovery mode.

### Restoring the Default GRUB Theme

If you want to revert to the default GRUB theme, edit the GRUB configuration file again:

```sh

sudo nano /etc/default/grub

```

Remove or comment out the `GRUB_THEME` line by adding a `#` in front of it:

```sh

#GRUB_THEME="/boot/grub/themes/theme-folder-name/theme.txt"

```

Then, update GRUB again:

```sh

sudo update-grub

```
