Q: USB keyboard prevents Bootcamp from starting.

It's a Razer Deathstalker. I have two other Razer periphrials plugged in via USB that don't affect Windows from booting. I have also tried having it plugged into my hub vs directly into one of the computer's USB ports. Either configuration prevents booting.

I don't have an Apple brand one but I have a few generic ones laying around I can test when I get home from work. The only issue I've found on MacOS is sometimes it won't work to type in my password but works perfectly once I'm into the desktop.

OK I have a generic Logitech that allowed booting. I'm wondering if it has something to do with the onboard memory I believe the keyboard has? But then again the other two Razer products that also have onboard memory don't prevent booting. I'm stumped...

I tested the same Razer keyboard on a Windows machine and it did not affect booting.

Yes it was.

I have bootcamp 5.1 it looks like. I haven't had Win 7 installed in awhile and skipped Win 8.1. It's starting to sound like its something I'll just have to live with.

I'm hesitant because I just spent a few days trying to get Windows 10 on a separate internal hdd in place of my SuperDrive and finally have a stable Windows OS running. Do you know if I can run a second bootcamp partition on the drive containing MacOS? I do have a Windows 7 install disc that I could install and test with. But then again if that worked I'd be stuck with Windows 7 then right?
