SCCM 2012, PXE boot stops working. I have SCCM version 1806.
The contact with DHCP gets the IP address, next download WDSNBP from my SCCM server. Everything looks working fine until I got the line "Press F12 for network service boot".
if I press F12 I got this error: " The Windows Boot Configuration Data (BCD) file from the PXE server does not contain a valid operating system entry. Ensure that the server has boot images installed for this architecture. Error code:0x0000098"
Else the computer skips the image mode and goes to Windows.
WDS has this error "The PXE server processed a request from a client of architecture x86x64. However, there were no boot images installed for this architecture. PXE clients of this architecture will not be able to complete the boot process successfully. To resolve this problem, add at least one boot image for this architecture."
If I use a DVD with the boot image the image process goes through without problems.
Things that I tested:
1-Disable PXE support on Distribution points waits for the server to remove the files, reboot and re-enable PXE again.
2-Create a new boot image.
3-Create a new task sequence.
4-Remove support for unknown computers.
