   2 Prepare Installation Media
   3 --------------------------
   4
   5 Download the installer ISO image from: {website}en/downloads/category/proxmox-mail-gateway
   6
   7 The {pmg} installation media is a hybrid ISO image. It works in two ways:
   8
   9 * An ISO image file ready to burn to a CD or DVD.
  10
  11 * A raw sector (IMG) image file ready to copy to a USB flash drive (USB stick).
  12
  13 Using a USB flash drive to install {pmg} is the recommended way because it is
  14 the faster option.
  15
  16 Prepare a USB Flash Drive as Installation Medium
  17 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  18
  19 The flash drive needs to have at least 1 GB of storage available.
  20
  21 NOTE: Do not use UNetbootin. It does not work with the {pmg} installation image.
  22
  23 IMPORTANT: Make sure that the USB flash drive is not mounted and does not
  24 contain any important data.

  27 Instructions for GNU/Linux
  28 ~~~~~~~~~~~~~~~~~~~~~~~~~~
  29
  30 On Unix-like operating system use the `dd` command to copy the ISO image to the
  31 USB flash drive. First find the correct device name of the USB flash drive (see
  32 below). Then run the `dd` command.
  33
  34 ----
  35 # dd bs=1M conv=fdatasync if=./proxmox-mailgateway_*.iso of=/dev/XYZ
  36 ----
  37
  38 NOTE: Be sure to replace /dev/XYZ with the correct device name and adapt the
  39 input filename ('if') path.
  40
  41 CAUTION: Be very careful, and do not overwrite the wrong disk!
  42
  43
  44 Find the Correct USB Device Name
  45 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  46 There are two ways to find out the name of the USB flash drive. The first one is
  47 to compare the last lines of the `dmesg` command output before and after
  48 plugging in the flash drive. The second way is to compare the output of the
  49 `lsblk` command. Open a terminal and run:
  50
  51 ----
  52 # lsblk
  53 ----
  54
  55 Then plug in your USB flash drive and run the command again:
  56
  57 ----
  58 # lsblk
  59 ----
  60
  61 A new device will appear. This is the one you want to use. To be on the extra
  62 safe side check if the reported size matches your USB flash drive.

  65 Instructions for macOS
  66 ~~~~~~~~~~~~~~~~~~~~~~
  67
  68 Open the terminal (query Terminal in Spotlight).
  69
  70 Convert the .iso file to .img using the convert option of `hdiutil` for example.
  71
  72 ----
  73 # hdiutil convert -format UDRW -o proxmox-mailgateway_*.dmg proxmox-ve_*.iso
  74 ----
  75
  76 TIP: macOS tends to automatically add '.dmg' to the output file name.
  77
  78 To get the current list of devices run the command:
  79
  80 ----
  81 # diskutil list
  82 ----
  83
  84 Now insert the USB flash drive and run this command again to determine which
  85 device node has been assigned to it. (e.g., /dev/diskX).
  86
  87 ----
  88 # diskutil list
  89 # diskutil unmountDisk /dev/diskX
  90 ----
  91
  92 NOTE: replace X with the disk number from the last command.
  93
  94 ----
  95 # sudo dd if=proxmox-mailgateway_*.dmg of=/dev/rdiskX bs=1m
  96 ----
  97
  98 NOTE: 'rdiskX', instead of 'diskX', in the last command is intended. It will
  99 increase the write speed.

 104 Using Etcher
 105 ^^^^^^^^^^^^
 106
 107 Etcher works out of the box. Download Etcher from https://etcher.io. It will
 108 guide you through the process of selecting the ISO and your USB Drive.
 109
 110 Using Rufus
 111 ^^^^^^^^^^^
 112
 113 Rufus is a more lightweight alternative, but you need to use the *DD mode* to
 114 make it work. Download Rufus from https://rufus.ie/. Either install it or use
 115 the portable version. Select the destination drive and the {pmg} ISO file.
 116
 117 IMPORTANT: Once you 'Start' you have to click 'No' on the dialog asking to
 118 download a different version of GRUB. In the next dialog select the 'DD' mode.
