@zeorin Thanks for that info. I had to do the following extra. Since I use LUKS encrypted disk and uefi.
1) Open the encrypted disk in File explorer 2) Mount the lvm partition on /mnt mount /dev/ubuntu-vg/root /mnt Mount boot mount /dev/nvme0n1p2 /mnt/boot Mount efi mount /dev/nvme0n1p1 /mnt/boot/efi Standard chroot mounts mount --bind /proc /mnt/proc mount --bind /dev /mnt/dev mount --bind /sys /mnt/sys mount --bind /run /mnt/run <-- This was not listed. Then chroot into /mnt After adding the new apt sources and pinning the grub version and 'apt update && apt upgrade' I had to manually install 'grub2-common'. It did not install by default with 'apt upgrade'. After this was done. I ran update-grub and grub-install. With efi mounted this worked and I could reboot with old working grub. This is bug needs to be fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853369 Title: [19.10] Boot hangs at "loading initial ramdisk" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1853369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
