I previously had VX 2.5.6 working great, and I downloaded and set up VX 3.0.0 identically to my previous install (I used the setup guide found here). What I'm encountering is that I can see the Grub loader, and part of the boot process, but then it goes to a blank screen with a flashing cursor. No login prompt, or anything. It just sits there. I redownloaded the file, double-checked the file sizes and sha1sums, and they're identical. Any ideas what I've done wrong?
