Automating Dell BIOS Configuration Using MDT

Written by

It’s been a busy couple of weeks for me, so I’m slowly going through a backlog of things to cover. The push to get modern continues with the third part of my series on automating the process of transitioning from BIOS to UEFI using MDT. Today's blog post discusses the process of configuring BIOS settings on supported Dell Inc. enterprise systems.

Configuring HP BIOS Using MDT

This is the second post in my series that explores one of the most common questions I’ve been asked from folks who are migrating to Windows 10: "How do I go about transitioning from BIOS to UEFI?". So naturally, I’m addressing this question. This time, I am going to discuss automating firmware configuration on supported HP (Hewlett-Packard) notebook, desktop, and workstation models. Now, it's not as if it's been no-man's-land before. I am fully aware that there are blogs out there that talk about doing this kind of thing and I’ve tried a few of the solutions with various rates of success. Still, the feedback I've been getting over the past few weeks has been that I should share my approach when working with the Microsoft Deployment Toolkit (MDT), so, here's my attempt to do precisely that.

BIOS to UEFI - The Easy Way: MBR2GPT

This article is the first blog post in a series I'll write over the coming days that will provide a comprehensive overview that explains how you can automate the process of transitioning from BIOS to UEFI during "wipe-and-load" OS deployment scenario. To be able to migrate from BIOS to UEFI effectively you need to understand how to configure firmware settings, such as secure boot, legacy support, and TPM device configuration, as well as how to use the MBR2GPT tool. Unfortunately, though it seems like a relatively straightforward process when using Microsoft Deployment Toolkit, based on questions I received as well as threads posted on TechNet over the past few weeks, there is still some confusion around this in the Windows technical community. Converting a device to UEFI comes with quite a few benefits including the ability to make full use of Windows 10 modern security features, so I thought it would be worth taking a few minutes to share my approach to dealing with BIOS to UEFI conversions.

Force LAPS Password Reset during MDT OSD

My customers often send me exciting cases. This particular one is especially interesting because it is common in infrastructures that use "Local Administrator Password Solution" (LAPS) for password management. LAPS, which I can't recommend highly enough, provides management of common local administrator account by setting a different, random password on every managed domain-joined computer. The case opened when a customer contacted me a few weeks ago reporting that they experienced issues when re-installing computers using Microsoft Deployment Toolkit: after OS deployment, LAPS didn't update the local administrator password which in turn significantly increased the risk of lateral escalation (Pass-the-Hash (PtH)) that results when the same administrative local account and password combination is used. Given the importance of the customer, I immediately sat down to investigate.

Continuing the theme of focusing on disk-related cases (yesterday I posted an article detailing how to fix the "Verify BCDBootEx" step failing on HP ProDesk 600 MT G3 systems), this post showcases yet another reason why you should stop deploying systems in Legacy mode. It also shows how a little time spent on reviewing log files to get a couple of clues can quickly lead to a solution.
