I was affected by this as well on my Intel NUC. The custom installed grub-install (the efi version) fails to write on the mSATA, ramdisk and USB-stick without reporting any errors!
I could boot flawlessly using LILO or change to grub-pc: sudo apt-get remove grub-efi grub-efi-amd64 sudo apt-get install grub2 sudo grub-install /dev/sdx -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1085908 Title: grub-install /dev/sdx silently fails when grub-efi but no grub-pc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1085908/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
