I don't have the Windows CD with me, and I don't mind making and using the Ubuntu CD, but Windows 7 is already installed on my computer. Now I want to get Ubuntu so that I can have the Ubuntu + Windows 7 dual boot option on boot. What should I do? Does Unetbootin fulfill my needs? If I must have a Windows 7 CD, what kind of CD do I need to make?
The UbuntuLive CD which you can download from the Ubuntu Website will give you the option of installing alongside your existing Windows 7 installation without damaging it.
It's always good to back up your data files, just in case anything goes wrong!
You don't need the Windows disk to install Ubuntu.
