Why are there 3 versions of Nobara in my GRUB menu?

By default, Nobara keeps the most recent 3 versions of the kernel, and a rescue kernel. This way if a kernel update fails, you can still boot into the previous working kernel:



You can run the following command to delete older kernel versions except the current running one and the last one:

# dnf remove $(dnf repoquery --installonly --latest-limit=-2 -q)

In addition to this, you can also change /etc/dnf/dnf.conf file to specify that you want to keep only last 2 versions of kernel. In this case, yum will automatically retain only the latest kernel and the one before, and delete the rest, every time it upgrades your kernel:

installonly_limit=2 #set kernel count

Save and close the file.
