This post will cover all the steps needed for bare metal deployment (Windows 10 20H2) using the configuration manager. The bare metal scenario occurs when you have a blank machine you need to deploy or an existing machine you want to wipe and redeploy without needing to preserve any existing data.
Microsoft released Windows 10, version 20H2 feature update aka Windows 10 October 2020 Update.
Note – With this release and future releases, the Windows 10 release nomenclature is changing from a year and month pattern (YYMM) to a year and half-year pattern (YYH1, YYH2). For example – “Windows 10 version 20H2” (instead of “Windows 10 version 2010”).
Introduction
The setup starts from a boot media, using a CD, USB, ISO, or Pre-Boot Execution Environment (PXE). You can also generate full offline media. The target can be a physical computer or a virtual machine.
The deployment process for the new machine scenario is as follows –
- Start the setup from boot media (CD, USB, ISO, or PXE).
- Wipe the hard disk clean and create a new volume.
- Install the operating system image.
- Apply device drivers by detecting device manufacturers.
- Install applications.
- Apply Customization, Additional settings if needed.
- After taking these steps, the computer is ready for use.
Prerequisites
- Ensure you are running with the latest supported version of Configuration Manager.
- Boot images are updated or regenerated.
- Make sure that you added network and storage drivers to the boot image.
- Configured the boot image to deploy from a PXE-enabled distribution point.

On the Install Applications page, specify the applications to install, or later you can add in task sequence steps. Click Next.
Review the settings, click Next.
Click Close to complete the wizard.
The Task Sequence is created successfully.
Customize Task Sequence
Use the following procedure to modify an existing task sequence
Under Software Library > Operating Systems > Task Sequences. Right-click on the task sequence and select Edit.
Edit the Task Sequence to add or remove settings – The Task Sequence uses these phases to determine which tasks must be completed.
You might need to add support files, software updates, tools, and applications to the task sequence based on requirements.
Review drivers and applications that will be installed with the task sequence. Before you deploy the task sequence, make sure the drivers are compatible. To Import Drivers, Create Driver packages and Process to Integrate Driver package into Task Sequence.
Review others settings added in Task Sequence, and make sure to apply all changes. Click Apply and OK, close the window.
Deploy Windows 10 20H2 Task Sequence
Select the task sequence, Right-click, and select Deploy.
On the General, click Browse to select your device collection where you wish to perform the deployment.
Deploy to All Unknown Computers – Computers that are not managed by Configuration Manager or a computer that is not imported into Configuration Manager.
On the Deployment Settings, select the Purpose of the deployment.
Available – Available deployments require that the user is present at the destination computer. A user must press the F12 key to continue the PXE boot process. If a user isn’t present to press F12, the computer boots into the current OS, or from the next available boot device.
Required – Required deployments use PXE without any user intervention.
To use a PXE-initiated OS deployment, For the Make available to the following setting, select one of the following options –
- Configuration Manager clients, media, and PXE
- Only media and PXE
- Only media and PXE (hidden)
Note – Use the Only media and PXE (hidden) setting for automated task sequence deployments. To have the computer automatically boot to the deployment without user interaction, select Allow unattended operating system deployment and set the SMSTSPreferredAdvertID variable as part of the media.
On the Scheduling tab, you can specify the schedule for this deployment. Click Next.
On the User Experience tab, leave the default selected options. Click Next.
On the Alerts page, leave it default. Click Next.

Troubleshooting – Windows 10 20H2 Using SCCM
The first step to troubleshoot SCCM OSD Task Sequence issues to is check out the SMSTS.log. Learn how to read SMSTS.log effectively for troubleshooting SCCM OSD Task Sequence.
The SMSTS.log updates the location depending on the phases of the deployment process.
| Phase | Log Location [Client Side] |
| WinPE (Before HDD are formatted and partitioned) | x:\windows\temp\smstslog\smsts.log |
| WinPE (After HDD are formatted) | x:\smstslog\smsts.log copied to c:\_SMSTaskSequence\Logs\Smstslog\smsts.log |
| Installed Operating System (Before SCCM client installed) | c:\_SMSTaskSequence\Logs\Smstslog\smsts.log |
| Installed Operating System (After the SCCM client is installed) | c:\windows\ccm\logs\Smstslog\smsts.log |
| Installed Operating System (When the Task Sequence is completed) | c:\windows\ccm\logs\smsts.log |
