First, we need to make some space available on the hard drive. To do that, boot into Windows and in the menu, find and open “Create and format hard disk partitions”:

Next, within the Disk Management tool we need to shrink the C: drive to make space for our Nobara Linux installation:

In this environment my C: drive was 100GB, so I shrunk it down by 50GB:

Next, you will need to download the Nobara ISO from https://nobaraproject.org/download-nobara/ and burn it to a USB stick using something like Balena Etcher.

Once you have burned the ISO to a USB stick, reboot into the USB stick. You may need to change the default boot device in your system UEFI BIOS boot settings to have it boot to the USB stick first.

After you have booted into the USB stick, hit Enter on the “Start Nobara 37” option:

This will enter into the Nobara 37 live USB environment. Go through the installer sections configuring settings to your liking.

When you get to the “Partitions” section, choose “Replace a partition”, then click on the empty space at the end of the “Current” bar:

Proceed with the rest of the installation after this.

When you reboot, Windows will come back up. We now need to enable the GRUB boot menu from within Windows.

To do this, open a Command Prompt as Administrator:

Then, enter the following command:

bcdedit /set "{bootmgr}" path \EFI\fedora\grubx64.efi

Now reboot, you should be greeted by the GRUB boot menu and be able to choose between Nobara Linux and Windows:

TO REVERT BACK TO WINDOWS BOOT LOADER:

If at any point you decide to remove your Nobara installation (delete the partitions) and want to revert back to the default Windows boot loader, again open a Command Prompt as Administrator in Windows and run:

mountvol S: /S
S:
cd .\EFI\
dir
rd /S fedora
bcdedit /set "{bootmgr}" path \EFI\Microsoft\Boot\bootmgfw.efi
