I am currently trying to perform a unattended install of Ubuntu Server 16.04 on an Intel UP² board using preseed and kickstart files.

For the moment, I am not really focusing on the unattended side of installation. I would just like to install an OS using preseed and kickstart.
I manage to get an ISO to work, but once Ubuntu Server is installed, I am not able to boot on it. I don't even see the GRUB screen, I get to a black screen and I am stock there. I tried to male Ctrl+Alt+F1 to F9 in order to open one of my tty, but it doesn't do anything.

To perform my ISO creation and USB burning, I took my inspiration on that post. Now I am going to show you exactly what I do, step by step.

Before that, let me tell you that new Intel UP² boards don't seem to handle MBR installation, so my USB key MUST be EFI bootable. (I am not sure if that how we say it, please correct me if I am wrong)

Assuming I have an Ubuntu Server ISO located at ~/Downloads :

# mount original ISO

sudo mount -o loop ~/Downloads/ubuntu-16.04.5-server-amd64.iso /mnt/iso



# copy data 

sudo cp -rT /mnt/iso /opt/ubuntuiso

So now I have a folder containing anything I need to make my ISO. I am using this preseed file (ks.preseed)

d-i partman-auto/method string lvm

d-i partman-auto-lvm/guided_size string max

d-i partman-auto/choose_recipe select atomic

d-i partman-partitioning/confirm_write_new_label boolean true

d-i partman/confirm_write_new_label     boolean true

d-i partman/choose_partition            select  finish

d-i partman/confirm_nooverwrite         boolean true

d-i partman/confirm                     boolean true

d-i partman-auto/purge_lvm_from_device  boolean true

d-i partman-lvm/device_remove_lvm       boolean true

d-i partman-lvm/confirm                 boolean true

d-i partman-lvm/confirm_nooverwrite     boolean true

d-i partman-auto/init_automatically_partition       select      Guided - use entire disk and set up LVM

d-i partman/choose_partition                select      Finish partitioning and write changes to disk

d-i partman-auto-lvm/no_boot            boolean true

d-i partman-md/device_remove_md         boolean true

d-i partman-md/confirm                  boolean true

d-i partman-md/confirm_nooverwrite      boolean true

And this kickstart file (ks.cfg)

And this grub configuration file (grub.cfg) :

if loadfont /boot/grub/font.pf2 ; then

    set gfxmode=auto

    insmod efi_gop

    insmod efi_uga

    insmod gfxterm

    terminal_output gfxterm

fi



set timeout=10

set default=0



menuentry "Automatically Install Ubuntu Server with Custom Config" {

    set gfxpayload=keep

    linux   /install/vmlinuz  file=/cdrom/preseed/ubuntu-server.seed quiet ks=cdrom:/ks.cfg preseed/file=/cdrom/ks.preseed --

    initrd  /install/initrd.gz

}

menuentry "OEM install (for manufacturers)" {

    set gfxpayload=keep

    linux   /install/vmlinuz  file=/cdrom/preseed/ubuntu-server.seed quiet oem-config/enable=true --

    initrd  /install/initrd.gz

}

menuentry "Multiple server install with MAAS" {

    set gfxpayload=keep

    linux   /install/vmlinuz  modules=maas-enlist-udeb vga=788 initrd=/install/initrd.gz quiet --

    initrd  /install/initrd.gz

}

menuentry "Check disc for defects" {

    set gfxpayload=keep

    linux   /install/vmlinuz  MENU=/bin/cdrom-checker-menu quiet --

    initrd  /install/initrd.gz

}

menuentry "Rescue a broken system" {

    set gfxpayload=keep

    linux   /install/vmlinuz  rescue/enable=true --

    initrd  /install/initrd.gz

}

Assuming all the previous files are located in ~/newIsoFiles :

# copy data into ISO folder

sudo cp ~/newIsoFiles/ks.* /opt/ubuntuiso/ubuntu

sudo cp ~/newIsoFiles/grub.cfg /opt/ubuntuiso/boot/grub/



# create ISO

sudo xorriso -as mkisofs -V "Unattended Server" -no-emul-boot -boot-load-size 4 -boot-info-table -iso-level 4 -b isolinux/isolinux.bin -c isolinux/boot.cat -eltorito-alt-boot -e boot/grub/efi.img -no-emul-boot -o /tmp/ubuntu16-server-unattended-install.iso /opt/ubuntuiso/



# treat ISO to make it bootable

sudo isohybrid --uefi /tmp/ubuntu16-server-unattended-install.iso



# Finally, burn it on USB

sudo dd if=/tmp/ubuntu16-server-unattended-install.iso of=/dev/sdb bs=4k

After that, I just put my USB stick in my UP² board and let everything get installed. Everything seems to work like a charm before the final reboot, after which I get a black screen without even seeing GRUB screen.

Can anybody see what am I doing wrong ?
