Bootcamp/Win 7: No device drivers were found Man, installing bootcamp on my late 2013 15" Retina MBP is a challenge!

I was struggling for a very long time with the issue of not having any control og mouse/keyboard when entering the windows installer. On the apple forums there were all kinds of advices, from redownloading the drivers to using specific USB ports, but what I eventually found to be helping me was this tip which I think mounts the drive in "legacy mode" or something like that:

Now I can control mouse and keyboard, but soon after the installer tells me that "No device drivers were found. Make sure that the installation media contains the correct drivers and then click OK".

I am using a USB hd which I have formattet to be an install disk with drivers and everything from the bootcamp installer. Additionally I tried downloading these drivers:

...and putting them on a USB pen-driver, but nevertheless, the windows installer can't see them and I can't get past this step. When I try to browse for the drivers I see two drives:


BOOTCAMP (C:)
BOOT (X:)

Program Files
sources
Users
Windows



(C:) is my bootcamp partition and I am assuming that (X:) is my install drive, but the file structure looks nothing like what it looks like from Mac OS X?? And there seems to be no drivers in any of these folders. Additionally, my USB pen-drive does not even show up.

I'm trying to install Windows 7 Pro 64-bit, btw. Tried the 32-bit version with same results.

How can I get the windows installer to recognize my device drivers?
I would recommend you trying to follow this kb (TS4599) by Apple and update the results in your question using an Edit: at the start of the edit.
