Navigating the Secure Boot Key Expiration in the Linux Ecosystem

For over a decade, the relationship between Linux distributions and PC hardware has relied on a quiet, underlying architecture to navigate the strict gates of UEFI Secure Boot. At the heart of this bridge is a single cryptographic key owned by Microsoft. However, that foundation is about to shift. With the legacy Microsoft UEFI Certificate Authority (CA) 2011 expiring this June, the open-source community is actively managing a transition to ensure systems continue to boot seamlessly. Here is a breakdown of what this expiration means, how it impacts the Linux ecosystem, and what you need to look out for to keep your machines running smoothly. Why Linux Relies on Microsoft Keys To understand the impact of the expiration, it helps to look at how Secure Boot functions on standard x86 consumer and enterprise hardware. When a computer powers on, the UEFI firmware checks the initial boot components against a built-in database of trusted keys. Because Microsoft keys are embedded by default in ...

if you have an sdcard take it out

Needs a file called install.wim which can be found inside the 'sources' directory in the iso 

In windows phone internals switch the phone to mass storage mode

Load the woa deployer application and browse to the wim file 


It is possible to keep windows mobile, I have only tested it with unchecking the box in the advanced tab 'keep windows mobile'

check 'compact deployment' to save space 

                          deploy

The process takes roughly half an hour. Make sure the phone is fully charged

Once it has completed, safely remove hardware. It's called 'qualcomm device' or something like that. Hold the power button to exit mass storage mode until the device vibrates. You should see a menu with options to boot into mass storage mode, start windows or if you have dual boot enabled, boot into windows mobile.

To dual boot you have to run through the oobe (out of box experience) setup and have booted to desktop at least once. Restart the phone and go into mass storage mode, tap on dual boot and tap enable
