If I remove all sata devices from my motherboard, upon reboot the bios says it has detected two hard drives, and then continues to boot into windows even though there are no hard drives physically connected to the motherboard. I have updated my bios, clear cmos, removed the battery from motherboard. While in windows I can have access to my hard drives data even though they are not physically connected. It appears their is a copy of my data stored somewhere that is allowing my pc to access. Where and how this could be possible. If I physically connect the hard drives to the motherboard the bios detects these but I don't know if I am physically booting off my hard drive or the virtual drive. Any ideas as this is a tricky one.
