Well, it came back. My computer restarted itself, presumably after downloading updates on the Win 7 install, and the BIOS is now "Shadowed". Not sure what this means or why, but after getting back into my OS X installation, all seemed fine.
Now, the computer starts up, says BIOS is shadowed for both System and Video, takes an extra few seconds to initialize the mouse, and posts a SMART drive check imminent failure on the Samsung HD. WTF. Now Windows 7 posts a disk error warning, prompting me to back up my files ASAP. I want to clone this Mini because the Dual Boot took a while to setup. What should I do? I bought this new in the box off eBay about a month ago. Should I just clone, wipe, and return it?
