Re: Windows 7 on Poweredge R230

Probably needs USB 3.0 drivers loaded.

Windows 7 isn't supported on servers. That doesn't mean it won't work, but you may run into strange issues, and you should not EXPECT it to work.

User 2008 R2 drivers when needed.

Why not install a supported OS on the hardware then run Windows 7 as a virtual machine?
