UNABLE TO BOOT LINUX – INTEL TXT
You have just installed a Linux distribution on your computer. You may have installed it as the primary operating system and wiped out your OEM Windows installation. Now however, your system refuses to boot into Linux and is spinning in an endless cycle of unsuccessful boots.
I trust that by now you have already tried the common solutions such as removing the USB installation media from the computer, enablining legacy boot or disabling secure boot from the UEFI BIOS firmware settings. The option you have probably overlooked, and perhaps did not even know existed, is Trusted Execution Technology.
Intel Trusted Execution Technology is a hardware based security mechanism that protects the system against software based attacks. In the words of Intel:
Intel Trusted Execution Technology enables an environment where applications can run within their own space – protected from all other software on the system.
Trusted Execution Technology is primarily used on servers. However, it is being adopted also into some business workstations. By design it requires a Trusted Platform Module (TPM) chip version 2.0 or 2.1. As the name implies, Trusted Execution Technology prevents the execution of any untrusted software. This includes your freshly installed Linux distribution that refuses to boot.
To couter this, switch your computer system on and enter the UEFI BIOS firmware settings. There will be an option for Trusted Execution Technology which you will need to disable. It will most likely be under an option such as Trusted Platform Module or Security Chip on the Security tab. After this the computer should be able to boot into the Linux distribution you have installed.
Do keep in mind that it is generally not recommended to disable any security features as it may expose your system to various threats. However, in situations like these, there may be no other options. Weigh the pros and cons carefully, and based on your assessment make the choice that is best for you.
