I was searching for this and among others found these threads/posts: thread 27962 post 405486 (sorry, can't post links) They imply it's possible, but I couldn't find anything regarding this on the forum. The only solution I found was to preformat the boot drive with MBR and then activate Win7. It's explicitly stated in a thread that DAZ + GPT doesn't work. So is the user in the thread I wrote about above wrong? Actually searching for daz gpt returns no results at all. Am I doing something wrong? Because in the first thread it sounds like there should be plenty of material.
