  • I am setting up dual boot, Windows and Ubuntu 18.04, for our computer labs (more than 40 computers).
  • We successfully set this up with an auto installer before. We re-image the machines with MDT and there is a task sequence to provide an empty partition for linux to use.
  • In the past the preseed file we made succesfully found that partition and used the max amount of space available.
  • We have all new computers now that HAVE to be run as UEFI. (No way around this long story).
  • I ran the auto installer I built and it didn't work. So I realized that I now have to reference the kickstarter and preseed file from grub.cfg and no longer txt.cfg. That worked!
  • There is only one thing that is NOT working and is perplexing me:
  • TLDR The partition options in the preseed for finding the max free space aren't working. Instead it gobbles up the entire disk drive for linux. :(
  • Link to my preseed: http://ada.evergreen.edu/~tc_michelle/anbrew.seed

    d-i partman-auto/method string regular

    d-i partman-lvm/device_remove_lvm boolean true

    d-i partman-md/device_remove_md boolean true

    d-i partman-lvm/confirm boolean true

    d-i partman-auto/init_automatically_partition select biggest_free

    d-i partman-lvm/confirm_nooverwrite boolean true

    d-i partman-auto/choose_recipe select atomic

    d-i partman-partitioning/confirm_write_new_label boolean true

    d-i partman/choose_partition select finish

    d-i partman/confirm boolean true

    d-i partman/confirm_nooverwrite boolean true

    d-i partman-md/confirm boolean true

    d-i partman-partitioning/confirm_write_new_label boolean true

    d-i partman/choose_partition select finish

    d-i partman/confirm boolean true

    d-i partman/confirm_nooverwrite boolean true

So I found out the culprit/s. I walked through the installation without a preseed and found out I needed to answer one more question:

d-i partman/unmount_active boolean false

I also commented out

d-i partman-auto/method string regular

It works :D
