You configured ConfigMgr for Windows Deployment via PXE network boot but in the SMSPXE.log file the message Warning: Matching Processor Architecture Boot Image (0) not found is reported.
Sometimes the client will also fail to boot and load WinPE for OS Deployment.
independently of the OS Architecture you’re deploying ConfigMgr does expect you to deploy both x85 and x64 boot images or the Matching Processor Architecture not found error message will be displayed in the logs, this can easily be achieved with the following command
copype x86 "\SZHV-CM01.mcse.labOSDBootWindows10WinPE x86"
Once the boot.wim file has been copied make sure to import it in the ConfigMgr console and make it available on Distribution Points so that the client can use it to boot into WinPE
Once all files are in place and available to the client the Matching Processor Architecture not found error will not displayed in the SMSPXE.log file.
