Repair dual-boot graphics install

I broke my dual-boot Windows7-Fedora install which uses grub2 (BIOS). So far I’ve got the Windows running again with my Nvidia RTX2080. Before the disaster, I had run the Fedora on this boot disk with drivers installed using dnf from the Fedora repository. When a new kernel is installed, dkms reinstalls the nvidia drivers. The system boots fine using the onboard graphics and no external graphics card. With the graphics card installed, I can boot into Fedora but get kicked into the single-user console.
I recovered the Fedora install (no graphics card) using a rescue disk and the following (in some order):

  • grub2-install /dev/sda
  • dracut --regenerate-all
  • grub2-mkconfig -o /boot/grub2/grub.cfg
  • vgchange -ay

I added the the graphics card and did

  • dnf reinstall “*nvidia*”
  • dracut --regenerate-all --force
  • grub2-mkconfig -o /boot/grub2/grub.cfg

The grub menu entry for linux ends with {%dracut…}

My Fedora system now boots but driver initialization still a problem. I’ve attached nvidia-bug-report.lognvidia-bug-report.loggz (133.0 KB)

Any help would be appreciated.

I’ve solved this problem. For better or worse I removed all nvidia
drivers to avoid conflicts. Drivers can’t be installed in graphics mode and kernel mods are difficult to manage in rescue mode. The solution was to install from “local” .run file
