====== Preseed Linux USB Create ======

To create an Auto-Install USB Stock with Mint 21.2 or later, use the following steps.

  - Download latest Linux Mint iso file https://www.linuxmint.com/edition.php?id=305
  - Insert USB stick, check with dmesg | tail to identify the usb device
  - Delete/Create FAT32 partition <code>su -
fdisk /dev/xxx
</code> create type c (Win95 FAT32 LBA) partition\\ See for details: https://askubuntu.com/questions/1064278/how-to-create-win95-fat32-lba-partition-type-on-32-gb-usb
  - create vfat filesystem on new partition <code>mkfs.vfat /dev/xxx1</code>
  - mount disk <code>mount /dev/xxx1 /mnt</code>
  - rename usb stick label if necessary/desired<code>mlabel -i /dev/xxx1 -s ::"CST_MINT212"</code>
  - mount iso and copy iso content directly to usb stick partition. Ensure hidden files/directories are copied as well.
  - copy custom_install directory to usb stick root
  - copy custom preseed files to usb stick preseed directory
  - edit /boot/grub/grub.cfg and add to end: <code>menuentry "Install Custom Linux Mint 21.2 Cinnamon 64-bit" {
	set gfxpayload=keep
	linux	/casper/vmlinuz  file=/cdrom/preseed/mint_allinone.seed boot=casper debian-installer/locale=en keyboard-configuration/layoutcode=en_GB console-setup/layoutcode=en_GB automatic-ubiquity quiet splash --
	initrd	/casper/initrd.lz
}
</code>
  - add syslinux.cfg to root with content:<code>default vesamenu.c32
timeout 100
