If you are installing ESXi on a disk that contains a previous installation of ESXi or ESX, or a VMFS
datastore, the installer provides you with options for upgrading. See the vSphere Upgrade documentation.
Install ESXi Interactively
You use the ESXi CD/DVD or a USB flash drive to install the ESXi software onto a SAS, SATA, SCSI hard
drive, or USB drive.
Prerequisites
n
You must have the ESXi installer ISO in one of the following locations:
n
On CD or DVD. If you do not have the installation CD/DVD, you can create one. See Download
and Burn the ESXi Installer ISO Image to a CD or DVD
n
On a USB flash drive. See Format a USB Flash Drive to Boot the ESXi Installation or Upgrade.
Note You can also PXE boot the ESXi installer to run an interactive installation or a scripted
installation. See PXE Booting the ESXi Installer.
n
Verify that the server hardware clock is set to UTC. This setting is in the system BIOS.
n
Verify that a keyboard and monitor are attached to the machine on which the ESXi software is
installed. Alternatively, use a remote management application. See Using Remote Management
Applications.
n
Consider disconnecting your network storage. This action decreases the time it takes the installer to
search for available disk drives. When you disconnect network storage, any files on the disconnected
disks are unavailable at installation.
Do not disconnect a LUN that contains an existing ESX or ESXi installation. Do not disconnect a
VMFS datastore that contains the Service Console of an existing ESX installation. These actions can
affect the outcome of the installation.
n
Gather the information required by the ESXi installation wizard. See Required Information for ESXi
Installation.
n
Verify that ESXi Embedded is not present on the host machine. ESXi Installable and ESXi Embedded
cannot exist on the same host.
Procedure
1 Insert the ESXi installer CD/DVD into the CD/DVD-ROM drive, or attach the Installer USB flash drive
and restart the machine.
2 Set the BIOS to boot from the CD-ROM device or the USB flash drive.
See your hardware vendor documentation for information on changing boot order.
