Can't repair windows 7 due to no keyboard/trackpad

[austinpike]

2014 15" MBPro, OSX Mavericks, Windows 7 bootcamp.

Was booting into Windows, only came up with a black screen, restarted, Windows needs to be repaired.
Once the repair screen comes up there is no way to continue as the keyboard and trackpad do not function.
External keyboard/mouse don't work either.

I assume it is because Win7 includes no native USB3 drivers, same as the issue with installing it.

Windows Recovery apparently won't load the drivers when it starts either.

Thought I could boot to the Win7 install USB I created for the MBPro (and choose repair option from there) but that has the same issue; no keyboard/trackpad so I can't continue. I thought the drivers were installed to the USB key by BootCamp Assistant, but if they are, Repair isn't loading them.

From the directions in that linked thread, it seems that OSX "primes" the Windows partition by installing the USB drivers. So maybe the drivers are just copied to the Windows partition, and not the USB drive?

Does anyone have any clever workarounds to repair my Windows install without having to just blow it away and start over? This is such stupid frustrating thing.

Related keyboard and trackpad driver is side loaded to Windows installation PE, but not WinRE. So I guess you need to find a way to load it in Windows RE. You can find dedicated driver under WinPE folder on your installation media. This folder is hidden and maybe set as a system folder by default.
You will probably need a Windows PC to complete driver loading preparation, since Mac OS c doesn't show even hidden files under finder by default.

For future reference, hitting "F8" repeatedly after selecting the Windows boot drive but before Windows loads brings up an advanced startup options screen. Keyboard works on this screen, which allows me to boot to a last known good configuration, among other options. So at least I can get into Windows for more troubleshooting.

There are still issues with the Windows install. It may be related to display drivers; I had recently connected the MacBook to an Apple Cinema display and I think it went downhill from there...
