I'm new to linux, and I'm having a fairly big issue.

I'm running ubuntu from a flash drive without installing it. The issue is, my computer doesn't have wifi and I have to use an external adapter. I have the adapter, the install disk, and I know how it works, but I can't install it on my linux setup because I can't access the internet. I know I need ndisgtk, but I can't get it without internet, which I can't use without the adapter, which I can't install without ndisgtk

Can anyone help me with a shortcut or tip of some kind? I can access all of my windows files while in ubuntu, if that helps. Any sort of download link for ndisgtk that I can slap onto my windows partition and use in ubuntu, anything?
