[EUC]: It is time to move to UEFI boot

January 4th, 2018

If you are rolling out Windows 10 using SCCM infrastructure you may experience the following problems:

1. Newly build Operating System prompts for BitLocker key without changes to BIOS or hardware.

2. If you PXE boot using Legacy BIOS and then change BIOS settings to UEFI secure boot using vendor’s utility after reboot your system won’t be able to find any booting device.

The root cause of this issue is that starting Kapy Lake build (Intel 7th generation processor) CPU platform no longer support TPM 2.0/MBR boot combination.

The workaround is to change PXE boot to UEFI and set system BIOS to UEFI secure boot. Note that the factory settings are already UEFI secure boot.

This issue was observed on the latest models made by Dell and HP.

Co-hosting SCCM PXE point, DHCP and WDS services

January 22nd, 2015

SCCM PXE point or SCCM PXE enabled distribution point can be co-hosted with DHCP services. This configuration though is not recommended but is fully supported by Microsoft.

In order to configure DHCP and Windows Deployment Services on the same host you must do the following:

1. Install DHCP and WDS

2. For DHCP configure option 60 with with the value PXEClient. Do not enable and configure options 66 and 67.

3. Go to WDS properties, tick an option ‘Do not listen on port 67‘

Now you can start using WDS or configure SCCM PXE option on the top of WDS
