Q: bootcamp 5.1 iMac 27" late 2013 issue

2. EFI installations do not expose hardware properly in some cases, even though your specific Mac Model supports both, which is a bit puzzling.
3. Before we install, we can try another test. From the USB Installer that you created for Windows 7, can you manually run the nVidia Installer?

Oct 22, 2015 2:16 PMby Loner T,Based on iMac (27-inch, Late 2013) - Technical Specifications, your iMac may have one of the following GPUs,
Graphics
- 3.2GHz
NVIDIA GeForce GT 755M graphics processor with 1GB of GDDR5 memory - 3.4GHz
NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory
Configurable to NVIDIA GeForce GTX 780M with 4GB of GDDR5 memory.
Which specific GPU do you have?
- 3.2GHz

Oct 22, 2015 2:35 PMby Loner T,Do you want to try the drivers for 770M from the nVidia website - http://www.nvidia.com/download/driverResults.aspx/92214/en-us ?
The other option is to re-download the BC drivers - Boot Camp Support Software 5.1.5640 and test.

- MacBook Pro (Retina, 13-inch & 15-inch, Late 2013)
- Mac Pro (Late 2013)
- iMac (21.5-inch & 27-inch, Late 2013)
- Windows 7, Windows 8, and Windows 8.1, 64 bit
If these do not work, I suggest re-installing W7 (without EFI Boot).

Oct 22, 2015 2:42 PMby mattiaiMac27,actually i tryed both.. Re-download doesn't work. Instead The graphic driver does (download from NVIDIA website).
but it's seems strange to me that The official BC package has so many problems (brightness doesn't work, mouse scroll doesn't work,...)
with yosemite and BC assistant auto download of driver i had perfect windows installation in The past..
