I have just swapped my disk from old motherboard
and Windows fails to boot, sometimes giving the message "Inaccessible_boot_device".
Why? (Quote from Paul's unofficial FAQ).
The problem lies in the IDE driver. If you've installed the bus
mastering IDE drivers for another chipset, Windows cannot boot with
those. You have to hook up your old motherboard, replace the busmastering
drivers with the default IDE drivers Windows ships with, and then
switch motherboards and safely boot into Windows. Anyway FAE recommends
you a clean install of Windows if possible.
