The download link for the Microsoft Windows 7 Beta does not work with Ubuntu and Firefox 3. I click the button that says “download” and SURPRISE! Nothing happens. It’s kind of sad really. All I wanted to do was test it on my laptop. My desktop, which runs linux, is the only one to have a dvd drive that can properly write a dvd without any issues (note that the laptop can do just fine reading dvds, but writing them is a worth another post) So, in the end, I won’t be testing Windows 7.

I’m trying to download the windows 7 beta version from my windows xp at home (in ubuntu I had the same problem as you) and… suprise! In opera browser: nothing happens, it remais loading (as in ubuntu); in google chrome: same as in opera but the page freezes after a minute.
Last chance: Internet Explorer. A pop up appears saying that the “msxml3.dll” plug-in has crashed and that Internet explorer needs to be closed.
Better luck next time!
You can do it, but it does take a bit of effort.
All you need to do is view source, and copy the URL for the button, and paste that into a new window (not a new tab; it will resize your window).
If you have Java™ installed, you’ll find that it will load a download manager applet. If you do not have Java installed, it’ll give you a straight download through the Web browser.
The URL you want is the really long URL contained in the JavaScript which is embedded directly in the tag for the download button. I was able to download both 32-bit and 64-bit Windows 7 this way. Windows 7 64-bit doesn’t work on any of my 64-bit computers, though the 32-bit release does work (on one of my computers, but not my primary workstation). All in all, I would say that it’s not ready to be a beta, anyway.
Strange. I was able to download my Windows 7 beta ISO off the official site. (seems like vista 2.0, imo… but it’s stable for a beta, so far)
