Install from USB Stick

The {pve} installation media is 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 {pve}.

Prepare a USB flash drive as install medium

In order to boot the installation media, copy the ISO image to a USB media.

You need at least a 1 GB USB media.

Note
 Using UNetbootin or Rufus does not work.
Important
 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
Note
 Be sure to replace /dev/XYZ with the correct device name.
Caution
 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
Tip
 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
Note
 replace X with the disk number from the last command. 
sudo dd if=proxmox-ve_*.dmg of=/dev/rdiskX bs=1m
Note
 'rdiskX', instead of 'diskX', in the last command is intended, this will increase write speed

Instructions for Windows

Download Etcher from https://etcher.io , select the ISO and your USB Drive.

If this doesn’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.
