How to Edit Global GRUB Bootup Options Using Virtualmin

Typically, you'd access anything related to configuring GRUB via the text-based Linux shell in a Linux server environment. However, with Virtualmin, you can use the GRUB Boot Loader module, which contains quite a few options that deal directly with GRUB. This guide will teach you how to edit the global GRUB boot options within Virtualmin. Of course, you should already have Virtualmin installed on your server with Webmin access before proceeding any further with this guide. If you're not certain how to do this, we have guides to help here:

• How to login to Webmin

Once you're ready to proceed, please refer to the following steps:

Step 1:  Click on the Webmin section

Step 2:  Click on the Hardware option

Step 3:  Select the GRUB Boot Loader module

Step 4: You should now see the GRUB Boot Loader interface

Step 5: Click the Edit Global Options button

Step 6: You should now see the Global Options interface

Step 7: Modify any of the options to your needs

Step 8: When you're satisfied, click the Save button

Any changes that you have made will take effect on the next reboot of the server.
