I am trying to install ubuntu on a netbook without a CD drive. I first attempted a flash drive, but it did not work, so I decided to use the flash drive to transfer the application that can install from the desktop.

However, this is a secondhand school computer that needs its borderline spyware security suite wiped before it can access the internet, so I cannot use the install from desktop application.

Do I have any other options? I do have access to an external CD drive that I could try, but I am unconvinced that I would get different results since it would have to go through a USB port.

Any and all input is very much appreciated!
