PXE Boot Basics. Booting from the network using the PXE protocol involves a simple series of DHCP packets. There are three parties involved: the DHCP server, the PXE server, and the client. The client broadcasts a DHCP packet asking for the address of DHCP servers (servers that can hand out IP addresses). PXE is an industry standard created by Intel that provides pre boot services within the devices firmware which enables devices to download network boot programs to client computers. PXE boot issues are one of the biggest call generators for the Configuration Manager Global Business Support (GBS) team which is in part due to the reliance on and interdependencies with networking protocols such as DHCP and TFTP. Nov 28, 2016 To test that PXE is working, boot the VM PC01 and it should get an IP from the DHCP server, prompt for F12 to be pressed and when F12 is pressed, display an error that looks like this: This is fine. This error is normal. The PXE boot process has worked but there are no boot images for it to load. Booting from the LiteTouch MDT image. Windows 10: Microsoft surface pro cannot boot to PXE Discus and support Microsoft surface pro cannot boot to PXE in Windows 10 Network and Sharing to solve the problem; Hi, I tried to boot Microsoft Surface by hold volume down button and Press and release the Power button to PXE boot but failed.
Preboot execution environment (PXE)-initiated OS deployments in Configuration Manager let clients request and deploy operating systems over the network. In this deployment scenario, you send the OS image and the boot images to a PXE-enabled distribution point.
Note
When you create an OS deployment that targets only x64 BIOS computers, both the x64 boot image and x86 boot image must be available on the distribution point.
You can use PXE-initiated OS deployments in the following scenarios:
Complete the steps in one of the OS deployment scenarios, and then use the sections in this article to prepare for PXE-initiated deployments.
Configure at least one distribution point to accept PXE requests
To deploy operating systems to Configuration Manager clients that make PXE boot requests, you must configure one or more distribution points to accept PXE requests. Once you configure the distribution point, it responds to PXE boot requests and determines the appropriate deployment action to take. For more information, see Install or modify a distribution point.
Note
When configuring a single PXE enabled distribution point to support multiple subnets it is not supported to use DHCP options. Configure IP helpers on the routers to allow PXE requests to be forwarded to your PXE enabled distribution points.
Note
In version 1810 and earlier, it's not supported to use the PXE responder without WDS on servers that are also running a DHCP server.
Starting in version 1902, when you enable a PXE responder on a distribution point without Windows Deployment Service, it can now be on the same server as the DHCP service. Apple noteworthy font. Add the following settings to support this configuration:
Prepare a PXE-enabled boot image
To use PXE to deploy an OS, you must have both x86 and x64 PXE-enabled boot images distributed to one or more PXE-enabled distribution points. Use the information to enable PXE on a boot image and distribute the boot image to distribution points:
Manage duplicate hardware identifiers
Configuration Manager may recognize multiple computers as the same device if they have duplicate SMBIOS attributes or you use a shared network adapter. Mitigate these issues by managing duplicate hardware identifiers in hierarchy settings. For more information, see Manage duplicate hardware identifiers.
Create an exclusion list for PXE deployments
Note
Microsoft Surface Won't Pxe Boot
In some circumstances, the process to Manage duplicate hardware identifiers may be easier.
The behaviors of each can cause different results in some scenarios. The exclusion list never boots a client with the listed MAC address, no matter what.
The duplicate ID list doesn't use the MAC address to find the task sequence policy for a client. If it matches the SMBIOS ID, or if there's a task sequence policy for unknown machines, the client still boots.
When you deploy operating systems with PXE, you can create an exclusion list on each distribution point. Add the MAC addresses to the exclusion list of the computers you want the distribution point to ignore. Listed computers don't receive the deployment task sequences that Configuration Manager uses for PXE deployment.
Process to create the exclusion list
RamDisk TFTP block size and window size
You can customize the RamDisk TFTP block and window sizes for PXE-enabled distribution points. If you've customized your network, a large block or window size could cause the boot image download to fail with a time-out error. The RamDisk TFTP block and window size customizations allow you to optimize TFTP traffic when using PXE to meet your specific network requirements. To determine what configuration is most efficient, test the customized settings in your environment. For more information, see Customize the RamDisk TFTP block size and window size on PXE-enabled distribution points.
Configure deployment settings
To use a PXE-initiated OS deployment, configure the deployment to make the OS available for PXE boot requests. Configure available operating systems on the Deployment Settings tab in the deployment properties. For the Make available to the following setting, select one of the following options:
Deploy the task sequence
Deploy the OS to a target collection. For more information, see Deploy a task sequence. When you deploy operating systems by using PXE, you can configure whether the deployment is required or available.
You can redeploy a required PXE deployment by clearing the status of the last PXE deployment assigned to a Configuration Manager collection or a computer. For more information on the Clear Required PXE Deployments action, see Manage clients or Manage collections. This action resets the status of that deployment and reinstalls the most recent required deployments.
Important
The PXE protocol isn't secure. Make sure that the PXE server and the PXE client are located on a physically secure network, such as in a data center to prevent unauthorized access to your site.
How the boot image is selected for PXE
When a client boots with PXE, Configuration Manager provides the client with a boot image to use. Configuration Manager uses a boot image with an exact architecture match. If a boot image with the exact architecture isn't available, Configuration Manager uses a boot image with a compatible architecture.
The following list provides details about how a boot image is selected for clients booting with PXE:
