I guess my question is, why are you wanting to dual boot? Why arent you just running your miners on Win7? Curious.
linux is better for mining.
I'm using windows for work.
I have never found that Linux was better than Windows for mining, they are the same for me. Usually for most people it comes down to familiarity/ease of use, and cost. Minus the cost of hardware, if you dont already have a Windows box running or a copy of Windows laying around, and have to install a OS, then free is always better. Yes, there are the inherent Windows crashes and things, but take that out of account and I have never seen any performance increases/decreases in hashing rate from one OS over another.
How would you say its better for mining? Maybe there is something I have missed all of these years.
