I'm getting something along those lines with a Vista-style green bar on a machine that has never seen Vista.
I bought a Dell Mini 9 with Ubuntu, cloned the Ubuntu to a larger drive and played with it for awhile. Then I installed W7 32bit, keeping the 24 MB OEM partition which typically has the Dell diagnostics. This installation was a little unique compared with the 30 +/- other Windows 7 installations I've done so far. Early in the installation under drive options when I deleted the Ubuntu partition, merged it with some unallocated space and formatted it, W7 asked permission to create a 200 MB partition for recovery options (I believe this is where it puts the winre.wim and boot.sdi files used with the setautofailover.cmd). W7 usually creates that partition but doesn't ask. That caught my attention.
Anyway, the boot screen is the green Vista style. Also, uniquely, the resume from Hibernate is not the new W7 orb but a white bar that offers "Press Space Bar to Pause Resume" or something like that. If you press the space bar, you are given the options to resume from hibernate or forget resume and reboot the system.
Now.... I don't really want to mess with it because...WOW is it working good on a Mini with a little ol' Atom processor!
With restart times like this I can live with a Vista boot screen. It's almost as though W7 sensed the SSD drive and automatically installed itself as the rumored "Netbook version of Windows 7."
