If your system's graphics card is not supported by Live Media or your system does not have a graphics card, the system boots in console mode when you insert the media. In this case, you cannot perform a GUI installation.
You have two alternatives:
Use the text installer image instead of the Live Media ISO image.
You can run the text installer on the local console without network access. See Using the Text Installer.
Perform a remote installation as described in How to Install Oracle Solaris From Live Media If Your System Boots in Console Mode.
Before You Begin
For this procedure, two networked systems are required: the system on which Live Media was booted (target system) and a remote system from which the installation will be performed. Both systems must have network access. The two systems do not have to be on the same subnet. However, the target system must be reachable from the remote system. Also, the remote system must be running an OS that supports a graphical desktop.
The default user login and password for Oracle Solaris is jack.
$ su root Password: solaris
The root password is solaris.
# svcadm enable ssh:default
# ifconfig -a
$ ssh -X IP-address-of-target -l jack
where IP-address-of-target is the output of the ifconfig –a command that you ran on the target system.
Running this command on the remote system opens a secure shell, enabling you to access the target system to use the GUI installer.
$ su root Password: solaris
# /usr/bin/gui-install
