Set boot mode fix for keyboard and mouse control

You are here:

Winclone users migrating Windows 7 Boot Camp may experience loss of keyboard and mousecontrol when booting into Windows.

Installing the Boot Camp device drivers will restore functionality but without keyboardand mousecontrol, there is no easy way to get the drivers installed.

Set a boot mode to temporarily provide keyboard and mousecontrol.

Open Utilities -> Terminal and type:

diskutil list
The results should look similar to this:
0: GUID_partition_scheme *251.0 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 199.3 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 50.8 GB disk0s4
disk0s4 is typically the designated Boot Camp partition identifier and “BOOTCAMP” the volume name. Use the partition number and volume name for your system in the command string as shown in the example below. This Terminal commandwill start Windows in a special mode where keyboard and trackpad are functional until the next reboot.
sudo /usr/sbin/bless –mount /Volumes/BOOTCAMP –setBoot –legacy –legacydrivehint /dev/disk0
Password:(enter administrator password)
If that command doesn’t work, set by device:
sudo /usr/sbin/bless –device /dev/disk1s4 –setBoot –nextonly –legacy
Password:(enter administrator password)
Next, selectRestartfrom the Apple menu. Do not hold the Option key while restarting.Keyboard and trackpad control may not be restored immediately. If that is the case, wait a few minutes and try the keyboard and trackpad again. Once trackpad control is working, launch the Boot Camp drivers setup file to install the Boot Camp drivers. Upon restart into Windows, the keyboard and mouse should function normally.
If needed, set the Startup Disk back to OS X in System Preferences.
