Windows 10: Dualboot remove OS

So I have recently made a dualboot on my PC because one of the boots is a REALLY destroyed version of windows (it misses some important drivers and the registry has been infected/harmed). I then have a COMPLETELY clean version of Windows, but my C and D drive still has all the files on the destroyed version of windows. How can I get rid of those and just have a completely new system?

Dualbooting Windows for CUDA

I'm thinking about picking up a 8800gs or something like that to mess around with CUDA. The thing is I'm running a 4850. I don't want any driver conflictions, so I thought about dualbooting 2 separate OSes, one with ATi drivers, and the other with CUDA drivers. Whenever I want to game I'd swap out the card and boot into the correct OS. Would this work? Is there an easier way? I'd like to keep my 4850 for now.

 

Bluetooth and dualboot with Linux

I have a common web-developer setup: dualboot of Linux (Arch) for work and Windows for entertainment. And I have bluetooth headphones (Sennheiser HD1 Wireless), that can bee connected to two devices. But there is a problem.

If I pair my headphones on windows, they are not recognized anymore on the linux. If I "unpair" them on linux and reboot into windows, it's not being recognize on windows anymore (so I have to unpair again and re-find the device again). I have been doing
that for 6 months and it has become .. emm ... mildly infuriating.

It feels like I have each OS using the same bluetooth "device id" but using a different "secret" for connection.

So, I have to options:

• change the device ID in one operating system (same way as MAC addresses for network adapters)
• make sure that both OSes use the same "secret"

Is one of these options available on Windows (what I have a legal 10 Home version ... or non-professional version)? Or should I try to fix this on the Linux side? Are there any tutorials for this you can link me to? Or some google keywords?

Buying second pair of headphones is NOT a good option.
