In a typical interactive installation, you boot the ESXi installer and respond to the installer prompts
to install ESXi to the local host disk. The installer reformats and partitions the target disk and
installs the ESXi boot image. If you have not installed ESXi on the target disk before, all data on
the drive is overwritten, including hardware vendor partitions, operating system partitions, and
associated data.
Note To ensure that you do not lose any data, migrate the data to another machine before you
install ESXi.
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 Network 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.
