After running apt upgrade on Ubuntu 20.04. Either choice returns an error below. This is a windows dual boot. I have backups and I am using timeshift. I am learning but still pretty new to this.

Hoping someone can help me figure out what to do next. Should I continue without installing grub?

nvme0n1p1: entire extended partition

nvme0n1p6: mounted at /boot/efi

nvme0n1p9: filesystem root

nvme0n1p8: /home

Apologies, I cannot comment yet.

You can try to fix the grub as I explain here.

Since you have windows installed it might have over written boot loader. try grub-install /dev/sdX, where /dev/sdX is the drive where your boot partition resides.

If you are able to boot into Ubuntu then run and then sudo os-prober and finally sudo update-grub. This should solve the problem. Post the results after doing the above.

If you are not able to boot then run a live boot session from a usb or a cd, and run the above commands.

For any more help try this.
