The Proxmox VE installation media is now a hybrid ISO image, working in two
ways:
An ISO image file ready to burn on CD
A raw sector (IMG) image file ready to directly copy to flash media
  (USB Stick)
Using USB sticks is faster and more environmental friendly and
therefore the recommended way to install Proxmox VE.
Prepare a USB flash drive as install medium
In order to boot the installation media, copy the ISO image to a USB
media.
First download the ISO image from
https://www.proxmox.com/en/downloads/category/iso-images-pve
You need at least a 1 GB USB media.
Using UNetbootin or Rufus does not work.
Make sure that the USB media is not mounted and does not
contain any important data.
Instructions for GNU/Linux
You can simply use dd on UNIX like systems. First download the ISO
image, then plug in the USB stick. You need to find out what device
name gets assigned to the USB stick (see below). Then run:
dd if=proxmox-ve_*.iso of=/dev/XYZ bs=1M
Be sure to replace /dev/XYZ with the correct device name.
Be very careful, and do not overwrite the hard disk!
Find Correct USB Device Name
You can compare the last lines of dmesg command before and after the
insertion, or use the lsblk command. Open a terminal and run:
lsblk
Then plug in your USB media and run the command again:
lsblk
A new device will appear, and this is the USB device you want to use.
Instructions for OSX
Open the terminal (query Terminal in Spotlight).
Convert the .iso file to .img using the convert option of hdiutil for example.
hdiutil convert -format UDRW -o proxmox-ve_*.dmg proxmox-ve_*.iso
OS X tends to put the .dmg ending on the output file automatically.
To get the current list of devices run the command again:
diskutil list
Now insert your USB flash media and run this command again to
determine the device node assigned to your flash media
(e.g. /dev/diskX).
diskutil list
diskutil unmountDisk /dev/diskX
replace X with the disk number from the last command.
sudo dd if=proxmox-ve_*.dmg of=/dev/rdiskN bs=1m
Instructions for Windows
Download Etcher from https://etcher.io , select the ISO and your USB Drive.
If this doesn&#8217;t work, alternatively use the OSForensics USB
installer from http://www.osforensics.com/portability.html
Boot your server from USB media
Connect your USB media to your server and make sure that the server
boots from USB (see server BIOS). Then follow the installation wizard.

== Write the ISO image to USB ==
In order to boot the installation media you need to copy the ISO image to your USB media. You need at least a 512 mb USB stick.
'''Note''': Using UNetbootin or Rufus does not work.
=== Instructions for Windows ===
*Make sure that your USB media is not mounted and does not contain any data.
*In order to copy the ISO, you need to rename it first, just rename the downloaded file from proxmox-ve_2.0-*.iso to proxmox-ve_2.0-*.raw.
*Download the [https://github.com/downloads/openSUSE/kiwi/ImageWriter.exe SUSE Studio ImageWriter] and run as admin.  If this doesn't work (e.g. Win7), you can use the [http://www.osforensics.com/tools/write-usb-images.html OSForsenics USB installer] instead
*Copy the image to your USB media
=== Instructions for GNU/Linux ===
You can simply use dd on unix like systems. First download the ISO image, then plug in the USB stick (you need to find out what device name gets assigned to the USB stick. You can compare the last lines of 'dmesg' command before and after the insertion, or use the 'lsblk' command and identify using the size if unique).
dd if=pve-cd.iso of=/dev/XYZ bs=1M
Be sure to replace /dev/XYZ with the correct device name (be careful, and do not overwrite your hard disk!)
=== Instructions for OS X ===
OS X can use dd as the unix systems, but first requires the ISO image to be converted before it can be copied over to the USB stick. First you will need to download the ISO image, then plug in the USB Stick. To get the device name by running 'diskutil list'. This command will output all the disk attached to the system, you should be able to match up the USB stick to the specs and name of one listed. To get the raw device, you can add an 'r' in front of the name, ex. /dev/disk4 would become /dev/rdisk4. Next you will an to open Disk Utility and eject each partition only (If you eject from Finder or the Desktop it will eject the entire disk, removing it completely from the system). Now we can convert the ISO and copy the new image over with. Note hdiutil will commonly add the .dmg extension to the output file, so you will end up pve-cd.img.dmg
  hdiutil convert -format UDRW -o pve-cd.img pve-cd.iso
  sudo dd if=pve-cd.img.dmg of=/dev/rXYZ
Be sure to replace /dev/XYZ with the correct device name (be careful, and do not overwrite your hard disk!)
== Boot your server from USB media ==
Connect your USB media to your server and make sure that the server boots from USB - and follow the installation wizard.
