Using TeraByte Boot Media on UEFI Systems

Boot Media and UEFI Systems

Computer systems that come from the manufacturer with Windows 8.x/10 installed include a new BIOS interface known as the Unified Extensible Firmware Interface (UEFI). This new BIOS interface boots media differently than a traditional BIOS. Microsoft also requires these systems to use a feature of UEFI called Secure Boot. When Secure Boot is enabled, the system will only boot items that have a digital signature that is included in the system firmware. The manufacturers include a digital certificate, provided by Microsoft, to boot Windows on their systems. Secure boot can be disabled (on non-ARM systems) to allow you to boot other operating systems and environments. Boot media must be specifically created for UEFI to allow UEFI to boot from it. However, most systems also include the ability to boot traditional boot media though a method or mode typically called Legacy or BIOS.

Using TeraByte Boot Media on UEFI Systems

When creating the boot media for a UEFI system itís important to understand which media will boot properly on the UEFI system. System settings may require changing to boot Image for Linux, Image for DOS, or BootIt Bare Metal depending on the implementation of UEFI on the system.

  • TBWinRE and TBWinPE (the Image for Windows boot media) support booting via CD or USB flash drive on UEFI systems. The BIOS can be in either UEFI mode or Legacy mode. Secure Boot is supported for TBWinRE created on Windows 8.x/10 systems and for TBWinPE created using the Windows 8.x/10 ADK.

    TBWinRE is automatically installed with Image for Windows on Windows 7/8.x/10. You must run TBWinRE to create your boot media. Note: When creating the TBWinRE boot media it's recommended to do so on the system on which it will be used as some systems require files not available on all systems.

  • Image for Linux (IFL) v2.79 or later supports booting via CD or USB flash drive on UEFI systems. Secure Boot is supported with IFL v2.81 or later. Attempting to boot IFL v2.80 or earlier with Secure Boot enabled will result in the boot being blocked.

  • Image for DOS (IFD) will not boot on UEFI systems configured in UEFI mode. To boot on these systems Secure Boot must be disabled and you must enable or use Legacy mode.

  • BootIt Bare Metal will not boot on UEFI systems configured in UEFI mode. To boot on these systems Secure Boot must be disabled and you must enable or use Legacy mode.
