Q: iMac 27 5K Bootcamp no keyboard or mouse

Just got the 5K iMac (love it)!


I have been fighting with this issue for about a day.

 

When I try to install Win7 via boot camp I am able to get to the Windows install screen after creating the DOS partition but my wireless keyboard and mouse to do not respond. I am unable to select anything on the install screen where you confirm the language. I'm basically helpless.

 

I browsed around the forums and tried a few things.

 

I originally had an 8GB USB 3.0 flash drive so I then got an 8GB USB 2.0 flash drive (took much longer to install the software and Windows ISO).

I've tried using a wired keyboard and mouse but they don't seem to help.

 

Not sure where to go next.

 

Thanks in advance,

A:

Things finally worked!

I gave it a rest last night, got up and removed all the bootcamp partitions bringing me back to "normal".

Brought out an external USB DVD drive and a Win7 x64 disc.

Started up Boot Camp Assistant and created the partition (100 GB) along with loading the drivers onto the USB 2.0 2GB flash drive.

Then the system rebooted on its own and used the external DVD to start the Windows installer.

The "new" thing this time is that I saw a spinning circle during the startup which moved with my BT mouse.

It could not install to the BOOTCAMP drive partition though, came up with an error that it had to be formatted FAT32 (which I thought it was). I selected the BOOTCAMP partition and formatted it. (be VERY careful you select the right partition because the Fusion drive has an SSD that is smallish {120 GB}, and if you format that one you will have to do a lot of Apple work to get things going again - as in a time machine restore. Trust me )

 

I was able to use the Apple wireless keyboard and mouse to do the complete Windows 7 x64 install. The Boot camp installer fired up right after Windows finished and put all the drivers in the Windows system. All the mouse features work in Windows.

 

Everything is right with the world.

 

Remember there are two types of people; those that have lost data and those that will loose data.

 

Thanks for everything,

    Interesting development.

    I was able to hit F8 during the Windows bootup and got to the startup selection screen where you can choose the boot options (like safe mode, safe mode with network support, etc.). In that DOS level screen my keyboard worked fine. I was able to select different options and then it would go to the original windows install screen where you select the language but with no keyboard or mouse.

    Weird!

     

    I'll keep playing with it and post any new developments.

    Disconnect all other peripherals except Keyboard/Mouse/USB (with BC+Windows ISO). You have already found out the hard way, to use a USB2 rather than a USB3 flash disk.

    Just did that exact thing.

    Used a USB mac keyboard, USB mouse, USB (2.0) BC with Windows ISO and had the same screen with no keyboard input.

     

    Weird thing is that I can F8 and use the BT keyboard to select Safe mode and still get the same install screen with not keyboard input.

     

    Very frustrating.

     

    I'll try some more combinations and see if I can get the input to work.

     

    Thanks,

    Are you using both USB and BT keyboards simultaneously? If you are, I suggest disconnecting the BT devices. Do you have any other storage connected to the iMac? Have you tried all the USB ports in the back of the Mac sequentially to test if any of them work? I had to use the right-most USB port when facing the iMac.

    Loner,

     

    Thanks for your responses.

    I did not test the different USB ports on the back, I was previously using the far left (viewing from the front).

     

    I've booted from a USB DVD drive with Win7 and it does the same thing (no keyboard). (so no BC driver issue)

     

    I'll play the USB port dance and see what happens.

     

    Such fun.

    Hi Brad,

     

    I have the same issue here, but cannot grasp all the steps you took. My questions:

    1.  After you brought it all back to normal, you started Bootcamp Assistent with a USB 2.0 flash drive and an external USB DVD drive with the Windows DVD inserted; what boxes did you check in de Bootcamp assistant? Only the last two?

    2. after the error message about the wrong format, how did you format the bootcamp partition? Did you go back to OSX and use Disk Utility?

    3. after the formatting of the bootcamp partition, how did you continue?

    I can confirm that this solution works on a 21,5" iMac (Late 2013).

     

    Using the bootcamp assistant to create a complete installation does not work. Apparently the only way to get USB support in the Windows 7 installation is to use the bootcamp assistant to create the supportfiles on a suitable USB stick and let the assistant detect the bootable DVD which in turns gives you a message that bootcamp assistant needs to modify the stick again in order to take that into account. Once the bootcamp assistant reboots the computer it's set to boot off of the DVD and to read the config off of the USB stick.

     

    Apple really needs to sort this one out as it seems just about any new mac is affected by this issue on Windows 7. Telling people to install Windows 8.1/10 just isn't good enough if they are advertising support for Windows 7.

    Well I spoke too soon it would seem. Machine rebooted to complete the installation and without keyboard/mouse functionality; wired or otherwise.

     

    However after som digging I found an updated driverpack:

     

     

    https://support.apple.com/kb/DL1721?locale=en_US&viewlocale=sv_SE

     

    Creating the usb-driver stick and using the updated drivers in this package in combination an external USB-DVD-Drive and Windows 7 SP1 x64 disc I was able to complete the process and successfully get Windows 7 x64 SP1 up and running on the machine.
