BIOS to UEFI SecureBoot on Lenovo Desktops Gotcha! Part II

Good news for those IT departments out there that want to automated the process of moving from BIOS to UEFI with Secure Boot on Lenovo Desktop Machines!

As you may recall from my last post, I’ve been struggling to get any Lenovo Desktop Machines to move from non-SecureBoot to SecureBoot. But I recently found out that Lenovo may have updated their BIOS to support this (could it be?) We got a tentative confirmation from our contact at Lenovo, so it was time to do some testing.

I got a Lenovo M700 Tiny (great machine), and updated to the latest BIOS version. Looks like the BIOS version created Aug 2016 added some SecureBoot functionality. Looking good!

I created a tool internally at 1E to test moving from various BIOS/CSM/UEFI/SecureBoot/MBR/GPT states, so I ran the tool, and low and behold, it passed. The new M700 Tiny Firmware update allows for Non-SecureBoot to SecureBoot.

I haven’t tested other Lenovo Desktops (yet), but I’m cautiously Optimistic that the M73/83/93 will be updated as well. For several of our customers, that’s a major percentage of machines that can now be updated.

The next thing to talk to Lenovo about is to change Laptops functionality so we can turn on UEFI with CSM support and without SecureBoot. This would allow us to install Windows 7 in UEFI mode.

Looking forwards to Microsoft Ignite in Sept 2016!
