I have downloaded the latest Ubuntu iso. I want to install it as a dual boot on office laptop. Unfortunately, I have no flash drive or a CD/DVD with me. I just have an enclosed internal HDD connected to my laptop via USB, which has the ISO in one of its drives. How can I go about doing this?
Is windows already installed on the laptop? Do you need to resize the windows partition? Check out this thread for instructions. There is a more updated explanation of setting up the dual boot in Vista.
A totally different a Wubi install. Unfortunately, that means another download for you. You install the wubi installer & it handles installing Ubuntu for you. You don't have to dual boot and you can have Ubuntu running at the same time as Windows, no virtual machine.
