Once that is done, we can simply copy over our favourite WinPE multi-tool and/or the contents of say a Windows 10 Install ISO onto that FAT32 partition and Secure-boot to it. We can therefore create a third Primary MBR partition on the E2B USB drive and format it as FAT32. However, the standard Windows and WinPE boot files are all signed by Microsoft, so we can Secure Boot to any Windows\WinPE OS that is present on the E2B USB drive. This means that many Windows 10 systems will have run a KB update which has added a DBx blacklist key entry into the UEFI firmware’s database, so that when you try to UEFI64-boot to the agFM partition, you may get some sort of security error:

If you are unsure how to make any necessary changes to enable the UEFI/BIOS, we recommend that you check your PC manufacturer’s support information on their website. If so, you will need to choose for UEFI to be the first or only option. In some cases, there are options to enable both UEFI and Legacy/CSM. To change these settings, you will need to switch the PC boot mode from one enabled as “Legacy” BIOS (also known as “CSM” Mode) to UEFI/BIOS (Unified Extensible Firmware Interface). To access these settings, you can consult your PC manufacturer’s documentation or follow these instructions: Run Settings > Update & Security > Recovery and select Restart now under Advanced startup. From the next screen, select Troubleshoot > Advanced options > UEFI Firmware Settings > Restart to make changes. Firmware, often called BIOS (Basic Input/Output System), is the software that starts up before Windows when you first turn on your PC. Most modern PCs are capable of Secure Boot, but in some instances, there may be settings that cause the PC to appear to not be capable of Secure Boot. These settings can be changed in the PC firmware. Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots). This article is intended for users who are not able to upgrade to Windows 11 because their PC is not currently Secure Boot capable. If you are unfamiliar with this level of technical detail, we recommend that you consult your PC manufacturer’s support information for more instructions specific to your device.
