Weekly Tip 64

Enable Secure Boot on Dell Optiplex/Latitude Models

First, remember that Secure Boot is only support on Windows 8 and higher. Windows 7 will NOT boot with Secure Boot enabled.

For this, you will need the Dell Command | Configure tool, available here: https://en.community.dell.com/techcenter/enterprise-client/w/wiki/7532.dell-command-configure. Install this tool on a reference machine. You will need to copy the C:\Program Files (x86)\Dell\Command Configure\X86_64 directory to the machines where you want the BIOS changed. You can do this Group Policy, ConfigMgr, or any other desktop management software. Once copied, you can execute this command (assuming that you copy that directory to C:\Windows\cckt):

C:\Windows\cctk\X86_64\cctk.exe –secureboot=enable

If you have your BIOS password protected, add “–valsetuppwd=<password>” to the end.

For those with ConfigMgr, you can build an application to run this. This application can also be added to your task sequences to set Secure Boot on all machines. I recommend a PowerShell script as your detection method if you use an application. This one works for me (or anything else using cckt):

# test for presence of cctk
If ((test-path C:\Windows\cctk\X86_64\cctk.exe) -eq $false) { exit }

# set variable for compare
$detection = “secureboot=enable”

# get current settings
$settings = C:\Windows\cctk\X86_64\cctk.exe –secureboot

# test settings, return if they match
If ($settings -eq $detection) { return $true }

It will exit immediately if it does not detect the cctk bits. This is a “bad” exit that will report not installed to ConfigMgr. It then compares what the setting should be to what the setting currently is current at. If they match, it returns that the application is installed.
