Section 3: Tips for Getting Started with Grub Customizer on Linux Mint and Linux Systems

Now that you have installed and launched Grub Customizer, let’s delve into some essential tips for getting started with this powerful tool on Linux Mint and other Linux distributions.

Create a Backup Before Making Changes

One of the first things you should consider doing before making any alterations is creating a backup of your current GRUB configuration. This is paramount as it will allow you to revert back to the initial settings if something goes awry. Grub Customizer provides an option to export settings through its interface. Additionally, you can create a backup of your configuration from the command line:

sudo cp /etc/default/grub /etc/default/grub.bak

The above command creates a backup of your current GRUB configuration. Should any issues arise after modifications, you can restore your backup with the following command:

sudo cp /etc/default/grub.bak /etc/default/grub

Use the Revert Function Wisely

Grub Customizer offers a handy Revert button, which can be a lifesaver when you need to undo the last changes you made. However, be cautious as it only reverts the most recent change. Therefore, it’s crucial to review your changes carefully before saving them.

Managing Boot Menu Entries

With Grub Customizer, you can effortlessly manage boot menu entries. For instance, if your system has multiple operating systems installed, you can easily change the order in which they appear, or even hide certain entries. This is done through the List configuration tab where you can use the up and down arrows to rearrange entries or uncheck boxes to hide them.

Customizing the Appearance of GRUB

Grub Customizer isn’t just about functionality; it also gives you control over the aesthetics of your boot loader. Under the Appearance settings tab, you can change the background image, font, and colors to make your GRUB screen more visually appealing. When selecting a background image, ensure it is in a supported format like PNG or JPG, and be mindful of the resolution.

Keeping an Eye on Resolutions

Speaking of resolution, when customizing the appearance, it’s important to choose a resolution that is supported by your monitor during the boot process. In the Appearance settings, you can find a list of resolutions. Choose one that matches your monitor’s capabilities to avoid display issues.

Utilize the Advanced Settings for Expert Configuration

For seasoned users who are well-acquainted with GRUB and its intricacies, the Advanced settings section is where you can modify kernel parameters, submenu options, and more. If you’re new to GRUB, it’s recommended to refrain from changing settings in this section unless you’re certain about what you’re doing.

Update the GRUB Configuration After Changes

After making all the desired changes, don’t forget to update GRUB for the changes to take effect. Grub Customizer usually prompts you to update. However, you can also do this manually by clicking on the Save button in the toolbar.

By utilizing these tips, you can effectively harness the capabilities of Grub Customizer to manage and customize your boot loader on Linux Mint and other Linux systems. Just remember to proceed cautiously and keep backups handy in case you need to revert to a previous configuration.
