Linux: Fedora Boot Option Doesn't Appear in GRUB Boot Menu After Installation

If you've recently installed Fedora (version 39) on your computer and have noticed that the GRUB boot menu no longer displays the option to choose which distribution to run, don't worry - this is a common issue that can be easily resolved.

Understanding the GRUB Boot Menu

The GRUB (GRand Unified Bootloader) boot menu is a graphical interface that appears during the boot process, allowing users to choose which operating system or kernel to run. By default, the GRUB boot menu should display a list of available options, including the Fedora distribution that you have installed.

Why the Fedora Boot Option May Not Appear

There are several reasons why the Fedora boot option may not appear in the GRUB boot menu, including:

The GRUB bootloader was not installed correctly during the installation process
The GRUB bootloader is not configured to display the Fedora boot option
The GRUB bootloader has been overwritten by another operating system or bootloader

Resolving the Issue

To resolve the issue and display the Fedora boot option in the GRUB boot menu, follow these steps:

Boot your computer using a live Fedora USB or DVD
Open a terminal window and run the following command to determine the name of your hard drive:

sudo fdisk -l

This will display a list of available hard drives and partitions on your system. Take note of the name of the hard drive where Fedora is installed (e.g. /dev/sda1).

Next, mount the root partition of your Fedora installation to the /mnt directory using the following command:

sudo mount /dev/sda1 /mnt

Replace /dev/sda1 with the name of your root partition if necessary.

Now, install the GRUB bootloader to the MBR (Master Boot Record) of your hard drive using the following command:

sudo grub2-install --target=i386-pc /dev/sda

Replace /dev/sda with the name of your hard drive if necessary.

Finally, update the GRUB bootloader configuration file using the following command:

sudo grub2-mkconfig -o /mnt/boot/grub2/grub.cfg

This will generate a new GRUB bootloader configuration file that includes the Fedora boot option.

In this article, we have covered the issue of the Fedora boot option not appearing in the GRUB boot menu after installation. By following the steps outlined above, you should be able to resolve this issue and display the Fedora boot option in the GRUB boot menu.
