No, it didn't. From your syslog: Jun 6 20:21:36 ubuntu ubiquity: grub-install: error: cannot open `/boot/efi/EFI/ubuntu/shimx64.efi': Input/output error. Jun 6 20:21:36 ubuntu kernel: [ 921.974168] FAT-fs (sda1): Corrupted directory (i_pos 133127)
It wasn't so corrupt that it couldn't be read, but enough that a new file could not be written. The EFI version of grub completely ignores the destination argument. You can tell it to install to /usr/bin and it it will work just fine, provided that it can write to /boot/EFI. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1462676 Title: grub fails to install. x86_64-efi system Windows 8.1 primary To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1462676/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
