I still find issues installing grub via 'd-i grub/installer' if there are more than one disk. Or it could be the other issue Dave Chiluk referred to in the post #23.
Tried this on Precise (12.04.4, 12.04.5) and Trusty with errors. d-i debconf/priority string critical d-i partman/early_command string debconf-set partman-auto/disk "/dev/sdb" # My partition recipe d-i grub-installer/only_debian boolean false d-i grub-installer/with_other_os boolean false d-i grub-installer/bootdev "/dev/sdb" I see the update grub run but ubuntu never boots after the install. I could only workaround these issues via a late_command to run the grub- install from the target itself via chroot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1012629 Title: grub-installer ignores "bootdev" setting in preseed file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1012629/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
