Last week I unplugged the hard drive in my second PC, plugged in a spare one, and installed the beta of Vista Ultimate in order to check out a couple of things. I haven’t used it enough to come to any conclusions about the OS as a whole, and the main thing I wanted to try out didn’t work. Betas and all that. Hey ho.

However. Yesterday evening I disconnected the Vista hard disk and plugged the Windows 2000 drive back in. And the machine refused to boot.

How on earth can the Vista install have hosed a disk that wasn’t even plugged in?
