If you install Solaris from the Solaris 10 Operating System DVD, the interactive GUI installation might fail. This failure occurs if the boot-device configuration variable is not set on the system.
To determine if the boot-device configuration variable is set, type the following command.
# prtconf -pv | grep boot-device
If the output of this command is boot-device: with no associated device, you cannot use the interactive GUI installation program to install from the Solaris 10 Operating System DVD.
Workaround: Use the interactive text installer to install Solaris 10 software. When the installation program asks you to select a type of installation, select option 3, Solaris Interactive Text (Desktop Session).
