Repair Fedora GRUB after grub2-mkconfig gone wrong

I was trying to enable fractional scaling in Fedora 39 using ChatGPT and he recommended the following: # NVIDIA's proprietary driver requires DRM KMS to be disabled for Wayland to work. # Edit the file /etc/default/grub and ensure the parameter nvidia-drm.modeset=1 is not set. # If it is, change it to nvidia-drm.modeset=0 or remove it. Then update the grub configuration with: sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg I did so and ran the command, only to find my GRUB Menu only showing me the Windows Boot Manager. I can boot into Windows without problems, but now GRUB cannot find Fedora. **Solution I am trying** I created a USB bootable drive with Fedora and, after doing a quick Google search (and more ChatGPT, besides being the culprit), I stumbled upon the following plausible solution (with my /dev partitions already inputted): # Mount the root filesystem sudo mount /dev/nvme0n1p7 /mnt/root # Mount the EFI partition sudo mount /dev/nvme0n1p6 /mnt/root/boot/efi # Bind-mount the virtual filesystems for dir in /dev /proc /sys /run; do sudo mount --bind $dir /mnt/root$dir done With that /mnt set up, I run sudo chroot /mnt, which worked as intented. I edited my /etc/default/grub file back to how it originally was, and then I tried to re-generate my grub.cfg file again with the command: grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg. Nevertheless, I keep getting the following error: /usr/sbin/grub2-probe: error: cannot find a device for / (is /dev mounted?).. I have tried several combinations of the mounting procedure without success, such as this one: sudo mount --bind /dev /mnt/root/dev sudo mount --bind /dev/pts /mnt/root/dev/pts sudo mount --bind /dev/shm /mnt/root/dev/shm sudo mount --bind /dev/disk /mnt/root/dev/disk sudo mount --bind /proc /mnt/root/proc sudo mount --bind /sys /mnt/root/sys sudo mount --bind /run /mnt/root/run I also tried to follow this guide , which attempts to solve a similar problem, and there, the command works. I don't know what I could be doing wrong. Any help is appreciated! **Output of lsblk** Device Start End Sectors Size Type /dev/nvme0n1p1 2048 845151 843104 411.7M EFI System /dev/nvme0n1p2 845824 878591 32768 16M Microsoft reserved /dev/nvme0n1p3 878592 783736831 782858240 373.3G Microsoft basic data /dev/nvme0n1p4 994082816 997033681 2950866 1.4G Windows recovery environmen /dev/nvme0n1p5 997033984 1000214527 3180544 1.5G Windows recovery environmen /dev/nvme0n1p6 783736832 785833983 2097152 1G EFI System /dev/nvme0n1p7 785833984 977303551 191469568 91.3G Linux filesystem /dev/nvme0n1p8 977303552 994080767 16777216 8G Linux swap
