| 8 | Oracle VM VirtualBox can install a guest OS automatically. You only need
|
|---|
| 9 | to provide the installation medium and a few other parameters,
|
|---|
| 10 | such as the name of the default user.
|
|---|
| 11 | </p>
|
|---|
| 12 | <p>
|
|---|
| 13 | You can perform an unattended guest installation in the following
|
|---|
| 14 | ways:

|

| 17 | <li>
|
|---|
| 18 | <p><b outputclass="bold">Use the Create Virtual Machine
|
|---|
| 19 | wizard.</b> An optional step in the wizard enables you
|
|---|
| 20 | to configure unattended installation. You can specify the
|
|---|
| 21 | default user credentials for the guest OS and also whether to
|
|---|
| 22 | install the Guest Additions automatically. See
|
|---|
| 23 | <xref href="create-vm-wizard.dita#create-vm-wizard"/>.
|

|

| 25 | <p>
|
|---|
| 26 | During this step, Oracle VM VirtualBox scans the installation medium
|
|---|
| 27 | and changes certain parameters to ensure a seamless
|
|---|
| 28 | installation as a guest running on Oracle VM VirtualBox.

|
|---|
| 33 | commands.</b><xref href="unattended-guest-install-example.dita#unattended-guest-install-example"/> describes
|

| 34 | how to perform an unattended guest installation for an Oracle
|

|
|---|
| 40 | When you first start a VM that has been configured for unattended
|
|---|
| 41 | installation, the guest OS installation is performed
|
|---|
| 42 | automatically.
|
|---|
| 43 | </p>
|
|---|
| 44 | <p>
|
|---|
| 45 | The installation operation changes the boot device order to boot
|
|---|
| 46 | the virtual hard disk first and then the virtual DVD drive. If the
|
|---|
| 47 | virtual hard disk is empty prior to the automatic installation,
|
|---|
| 48 | the VM boots from the virtual DVD drive and begins the
|
|---|
| 49 | installation.
|
|---|
| 50 | </p>
|
|---|
| 51 | <p>
|
|---|
| 52 | If the virtual hard disk contains a bootable OS, the installation
|
|---|
| 53 | operation exits. In this case, change the boot device order
|
|---|
| 54 | manually by pressing F12 during the BIOS splash screen.
