With Windows 11, we were instructed to use GPT/UEFI when using Rufus to create a Windows 11 Insider ISO. Rufus has changed their policy and in order to use the newly created ISO states that Secure Boot must be disabled. Can Microsoft offer any help here?

Oh! I could be wrong but I think I know what's going on. If you download/use the official ISO, it contains both Home & Pro and it's too big for FAT32, therefore Rufus changes to NTFS automatically.
Ahhh that makes sense.
So that means we would have to turn off Secure Boot.
@Hawkeys46, how old is your system? Newer systems have other capabilities..
This is my install USB drive on Z490 (10th Gen) and Z590 (11th Gen) systems. It may be this will work all the way back to the 8th Gen processors since Microsoft chose to only allow those and later with Win 11. It ia not hard to set this up..

Yes, no big deal.
Windows will install properly, you can enable back Secure Boot afterwards.
edit: I used an ISO from UUPdump with only Pro inside, that's why Rufus stays FAT32 in my case.

Nothing to be concern about.
That installation media will boot just fine even if Secure Boot is enable and Windows will install properly.edit:
Wait, did you select NTFS? if so, then I'm not sure about my comment.
I always let Rufus decide, the default is FAT32.
It defaulted to NTFS I did not change the section below.
Edit: I have made at lots of ISO's using Rufus and have never used FAT32. Never had any issues with Clean Installs. Rufus has changed!
I just made 2 ISOs, one with default FAT32 that boots just fine with Secure Boot enable, and one with non-default NTFS which does not boot with Secure Boot enable (your case). You should use default.
