Thank you for taking the time to report this bug and helping to make Ubuntu better.
I note the following messages Aug 12 23:47:46 ubuntu kernel: [ 356.482177] FAT-fs (nvme0n1p1): error, fat_get_cluster: invalid cluster chain (i_pos 0) Aug 12 23:47:47 ubuntu grub-installer: grub-install: error: cannot open `/boot/efi/EFI/ubuntu/grubx64.efi': Input/output error. I would suggest `fsck` (ie. performing a file system check) or `badblocks` of your EFI partition, or ensuring 'fastboot' is disabled in windows 10 to ensure the EFI partition is left in a clean state. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1839894 Title: Installing Ubuntu 18.04.3 LTS alongside Windows 10 (Dual Boot) causes grub install to fail with fatal error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1839894/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
