| 7 | <p>In the <b outputclass="bold">Devices</b> menu in the virtual machine's menu bar, <ph
|

| 8 | conkeyref="vbox-conkeyref-phrases/product-name"/> has a menu item <b outputclass="bold">Insert Guest Additions
|
|---|
| 9 | CD Image</b>, which mounts the Guest Additions ISO file inside your virtual machine. A Windows guest should then
|
|---|
| 10 | automatically start the Guest Additions installer, which installs the Guest Additions on your Windows guest. </p>
|
|---|
| 11 | <p>For other guest operating systems, or if automatic start of software on a CD is disabled, you need to do a manual
|
|---|
| 12 | start of the installer. </p>
|
|---|
| 13 | <note>
|
|---|
| 14 | <p>For the basic Direct3D acceleration to work in a Windows guest, you have to install the WDDM video driver
|
|---|
| 15 | available for Windows Vista or later. </p>
|
|---|
| 16 | <p> For Windows 8 and later, only the WDDM Direct3D video driver is available. For basic Direct3D acceleration to work in Windows XP guests, you have to install the Guest Additions in Safe Mode.</p>
|
|---|
| 17 | </note>
|
|---|
| 18 | <p>If you prefer to mount the Guest Additions manually, you can perform the following steps: </p>
|
|---|
| 19 | <ol>
|
|---|
| 20 | <li>
|
|---|
| 21 | <p>Start the virtual machine in which you have installed Windows. </p>
|
|---|
| 22 | </li>
|
|---|
| 23 | <li>
|
|---|
| 24 | <p>Select <b outputclass="bold">Optical Drives</b> from the <b outputclass="bold">Devices</b> menu in the
|
|---|
| 25 | virtual machine's menu bar and then <b outputclass="bold">Choose/Create a Disk Image</b>. This displays the
|
|---|
| 26 | Virtual Media Manager, described in <xref href="virtual-media-manager.dita#virtual-media-manager"/>. </p>
|
|---|
| 27 | </li>
|
|---|
| 28 | <li>
|
|---|
| 29 | <p>In the Virtual Media Manager, click <b outputclass="bold">Add</b> and browse your host file system for the
|
|---|
| 30 | <filepath>VBoxGuestAdditions.iso</filepath> file. </p>
|
|---|
| 31 | <ul>
|
|---|
| 32 | <li>On a Windows host, this file is in the <ph conkeyref="vbox-conkeyref-phrases/product-name"/> installation
|
|---|
| 33 | directory, usually in <filepath>C:\Program files\Oracle\VirtualBox</filepath>. </li>
|
|---|
| 34 | <li>
|
|---|
| 35 | <p>On macOS hosts, this file is in the application bundle of <ph
|
|---|
| 36 | conkeyref="vbox-conkeyref-phrases/product-name"/>. Right-click the <ph
|
|---|
| 37 | conkeyref="vbox-conkeyref-phrases/product-name"/> icon in Finder and choose <b outputclass="bold">Show
|
|---|
| 38 | Package Contents</b>. The file is located in the <filepath>Contents/MacOS</filepath> folder. </p>
|
|---|
| 39 | </li>
|
|---|
| 40 | <li>
|
|---|
| 41 | <p>On a Linux host, this file is in the <filepath>additions</filepath> folder where you installed <ph
|
|---|
| 42 | conkeyref="vbox-conkeyref-phrases/product-name"/>, usually <filepath>/opt/VirtualBox/</filepath>. </p>
|
|---|
| 43 | </li>
|
|---|
| 44 | <li>
|
|---|
| 45 | <p>On Oracle Solaris hosts, this file is in the <filepath>additions</filepath> folder where you installed
|
|---|
| 46 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/>, usually <filepath>/opt/VirtualBox</filepath>. </p>
|
|---|
| 47 | </li>
|
|---|
| 48 | </ul>
|
|---|
| 49 | </li>
|
|---|
| 50 | <li>
|
|---|
| 51 | <p>In the Virtual Media Manager, select the ISO file and click the <b outputclass="bold">Add</b> button. This
|
|---|
| 52 | mounts the ISO file and presents it to your Windows guest as a CD-ROM. </p>
|
|---|
| 53 | </li>
|
|---|
| 54 | </ol>
|
|---|
| 55 | <p>Unless you have the Autostart feature disabled in your Windows guest, Windows will now autostart the <ph
|
|---|
| 56 | conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions installation program from the Additions ISO.
|
|---|
| 57 | If the Autostart feature has been turned off, choose <filepath>VBoxWindowsAdditions.exe</filepath> from the CD/DVD
|
|---|
| 58 | drive inside the guest to start the installer. </p>
|
|---|
| 59 | <p>The installer will add several device drivers to the Windows driver database and then invoke the hardware
|
|---|
| 60 | detection wizard. </p>
|
|---|
| 61 | <p>Depending on your configuration, it might display warnings that the drivers are not digitally signed. You must
|
|---|
| 62 | confirm these in order to continue the installation and properly install the Additions. </p>
|
|---|
| 63 | <p>After installation, reboot your guest operating system to activate the Additions. </p>
