Hi "prohibited ",
From my experience, if the WINPE always get restart you might can try this step here...
Problem:=========
You use the SCCM to enable PXE point to deploy the OS image, but the target machine failed to boot from PXE and reboot again and again.
Analysis:========
1. check your PXE point, it is no problem
2. check your WDS configurations, it is no problem
3. check your SCCM Task Sequences configurations, it is no problem
4. In the WINPE, open the command window and check the “SMSTS.log”, found the target machine failed to solve the SCCM server FQDN
5. check the DHCP configurations and found the DNS server is defined in the DHCP
Resolution:==========
1. In the DHCP console, define the correct DNS sever
2. Add the target machine IP subnet into SCCM site boundary
3. Re-advertise the OS deploy to target machine
4. Now the target machine boot from PXE successfully
Good Luck...
