installation - "PXE-E61: media test failure" while trying to install Windows Server 2008

I was trying to install Windows Server 2008 R2 on my new Dell XPS Laptop. A "PXE-E61: media test failure" error was showing while trying to install from DVD Drive of the laptop. I tried to troubleshoot it using the following steps, but didn't succeed.

1. Made HDD the first option in the boot order priority.


2. Disabled Inbuilt NIC. Didn't find any option to disable PXE boot.


3. With the same DVD I was able to install Win2008 on a desktop machine. In the desktop machine, the Wind2008R2 installation prompts with a menu with number 1. and 2. nothing next to it, usually I select option "1" and hit enter key.



4. To make sure there's no problem with the laptop HDD and DVD drive. I tried installing the Windows 7 Home premium on the laptop using the accompanied disk that came along with the laptop. The installation went successfully without any issues.

I am not sure why this issue only shows up in my laptop and not on my desktop machine. Please help me to sort this out.
