I don’t know if anyone will still be looking at this post now.

I’ve tried several times in the last few days to set up a Windows 7 partition on an iMAC (osx 10.8.5).

I think I’ve tried just about all the suggested fixes listed previously: USB2.0, USB drive in left hand port (although not sure if this was relevant to the iMAC) and the Terminal commands provided by RockOn23. None of these made any difference.

I also followed Coolio93’ss instructions, although it is not totally clear to me what step 3 should be. His words ‘this time select to install support media to the USB drive confused me, as there is only the option to download. I did the download again, but came up with another error 0xc0000428 about Windows cannot verify the digital signal for AppleSSD.sys. This appeared to be because doing the download again overwrote the specific Bootcamp files (version 5.1.5640) for my iMAC.

Can anyone shed light on how the third step should be run?

Also would using a USB2.0 wired keyboard work, or is it the ports themselves that aren’t enabled at all?

Any help/suggestions greatly appreciated.
 
No, still not found a solution. I’ve put it down for a few days to look for other suggestions.

Have tried with Logitech USB2 wireless keyboard/mouse after disabling Bluetooth in OSX (which was another suggestion I found).

I found another suggestion for the Terminal command, which said that the command would need a few other options needed to be added to the command. I haven’t tried this yet – I’m not familiar with the Terminal commands, so a little bit reluctant to run it.

I’ve just seen the post from fgargano01 and will have a look at that
 
Ok, a late reply, maybe you have figured it out already but regarding the "Cannot verify the digital signal for AppleSSD.sys, you need to navigate and find the AppleSSD.sys file and DELETE IT. You can do this the easiest way by just searching for it in "All my files", then press "This Mac", on the MAC OS, it might take a while but eventually it will probably pop up.

Regarding the keyboard and mouse not working am I exactly in the same situation as you. I also have an iMac and a solution to this would be fantastic :)

Apologies, I posted to the next reply...

Thanks for the information/suggestion, but unfortunately still not working.

I ran the utility against the USB stick I created from bootcamp, which contains the Windows pre-environment and the Win7 install iso and other stuff. I ran the utility on a Windows7 PC and pointed it at the root of the USB drive. I could see the DISM process running and all looked good. The process ran for over an hour (Intel reckoned about 15 minutes), but there were no complaints from the software and it finished successfully. I noticed on the Readme information sheet available at the Intel link, that it talked about overcoming the problem of no keyboard/mouse available on the screen to select the preferred language. All my previous attempts have successfully got past this screen, i.e. keyboard/mouse still working. It is the after subsequent reboot when I am presented with the screen to name the PC that the keyboard/mouse stop working. Unfortunately I still had the same problem. I don't know if I should/could run the process any differently?
 

this method worked fine, that program added usb3 support for my win7 installation usb disk and keyboard/mouse started working, it took ~10 mins for my flash to update drivers...

but at the end, after installing win7, it loads to "set up windows" menu with username and passwoed choosing and there is still mouse/keyboard is not working

and looks like this fixed last problem:
type in console: diskutil list
- search for the identifier of the Windows 7 hdd
change disk1s4 to your disk identifier
- Terminal prompt: sudo /usr/sbin/bless --device /dev/disk1s4 --setBoot --legacy
next type in console: sudo reboot
and just wait for system being restarted

I had the same problem; mouse and keyboard not working when starting Windows 7 installation from USB Stick

- Terminal prompt: diskutil list
- search for the identifier of the Windows 7 install USB stick, e.g. disk1s1
- Terminal prompt: sudo /usr/sbin/bless --device /dev/disk1s1 --setBoot --nextonly --legacy
- restart
- machine boots into Windows 7 installation with needed drivers

This worked for me perfectly. I realize it's an old post but in case others are out there trying this - this worked great. Thanks!
 
Here is the ultimate solution for Using Keyboard and Mouse, on this page, there is my guide in Italian, using a translator to read the steps.



Bye
 
I think I have a far, far simpler solution for anyone who has no mouse or keyboard input when you get to the windows setup. Try this:

1) When you get to the Windows setup screen and have no keyboard or mouse input, power off your mac by holding down the power button.
2) Remove the USB stick containing your windows image.
3) Turn the mac back on.

Voila. You now have mouse and keyboard input. Maybe put the USB back in at this stage but it is likely the installation is complete by now and you don't need to.
