Alright, so I set up my external hard drive to install windows, I've done this before. However this time, I get it booted, it starts to load windows, then the weird flashy windows 7 logo pops up, starts loading. It finishes loading, then I see a screen with a green/blue wallpaper with a plant-like thing on it. I can move my mouse around, but there's nothing on the screen, like... Nothing's going on, no HDD activity, nothing.
Whats going on here, and how can I fix this? I'm trying to go from Vista 32 to Windows 7 64
EDIT: My installation stops at disk.sys on the safe mode install.
