I recently purchased a new desktop with Win 8 preinstalled. However, I have much unfinished work on my old hdd from my other desktop which runs on Win 7. I was planning to just swop out the hdd's but when I put my Win 7 hdd in the new desktop it says "no operating system found" when booting up. Is there any way I can get the new desktop to recognise the win 7 hdd. I really don't feel like re-installing all the software which I use on my Win 7 hdd onto the Win 8 drive.
