I use a disk based on PE 5 that includes some programs I use for recoveries. It also includes NVDA (http://www.nvda-project.org) as I am totally blind.
When written to a flash drive it boots fine on UEFI based systems but only if I disable secure boot which is a massive problem for me as asking someone to disable it for me every time I need to boot into PE simply isn't practical.
I have tried to make a secure boot compatible image using a tool called UEFI_Multi. The process seems to complete without any issues - files are written to the disk, but when I attempt to boot using it it doesn't work. Again, it boots without a problem when secure boot is disabled.
Can anyone advise me as to where I might be going wrong or how to create an image that will boot with secure boot enabled? I know that the home of UEFI_Multi is reboot.pro? but I can't create an account there because of their captcha.
