Q: Error while trying to partition disk

When my USB is plugged in, after holding the option key, it shows my Mac disk, and the Windows disk. If its not plugged in, it just shows my Mac disk.

The installer does start, yes! I get into the installer, select my language, blah, blah, blah. But after that part, when its about to install Windows, it says that it can't find it!

I guess I can't. But what I'm in is the Windows Setup. It says "Load Driver."

The Error I get is this.

"A media driver your computer needs is missing. This could be a DVD, USB or Hard disk driver. If you have a CD, DVD, or USB flash drive with the driver on it, please insert it now."

So, I guess my USB is missing some kind of device driver? Which I guess I don't understand, if my computer can see it- after holding alt/option. But I guess the setup instillation doesn't see it.

Oh, that doesn't sound good. I downloaded it from the Apple support page too, so that's lame. Anyways, the name of the file is Win10_1511_1_English_x64.iso

I'm not sure what you're referring to- MD5sum or where I could find that.

Still no good! I got the iso image from the site you posted above. Downloaded it, got it onto my USB, no problem. But when I got to the setup part, again, it said that I was missing a media driver! Am I missing something here?

I just deleted that particular download. I'm trying a different one now. I'm running a Mid 2012 Macbook Pro Retina. Which, at least according to the Apple Bootcamp support page, should be able run Windows 10.

And actually, I did try running that command on the other Windows 10 download-- the one I got from before hand. I typed it in just as you had highlighted, and it said that there was no existing file directory or something.
