Re: Installing Debian on a Minnowboard Turbot with installer on USB stick?




Hi,

i created an ISO with this partition table:

  $ /sbin/gdisk -l test.iso
  ...
    MBR: protective
  ...
    GPT: present
  ...
  Number  Start (sector)    End (sector)  Size       Code  Name
     1              64         7713831   3.7 GiB     0700  ISO9660
     2         7713832         7714663   416.0 KiB   EF00  Appended2

by

  mnt=/mnt/iso

  sudo mount firmware-buster-DI-alpha2-amd64-DVD-1.iso "$mnt"

  xorriso -as mkisofs \
    -o test.iso \
    -r \
    -V 'Debian buster-DI-a2 amd64 1' \
    -partition_offset 16 \
    -append_partition 2 0xef "$mnt"/boot/grub/efi.img \
    -appended_part_as_gpt \
    "$mnt"

It will not work from DVD and not in BIOS Legacy mode. (On MS-Windows it
will not show long file names. I avoided complaints about symlinks by
avoiding option -J.)

But if started as reported by Rick Thomas:

then there should be a mountable Debian ISO in partition 1.
So the initrd stuff should get over the error occasion "Incorrect CD-ROM
detected".

(I meanwhile expressed my view about the ISO detection code in
  https://lists.debian.org/debian-cd/2018/06/msg00000.html
)


Have a nice day :)
