November 28, 2025Nov 28 Hello,I tried creating an unRAID USB using the all-in-one tool from the unRAID website; did the make_bootable.bat procedure as admin. This drive did NOT work (was not seen as a bootable media, UEFI-shell device listing does show it as detected).I made a memtest86 USB using its installer, and this works, so I know the QNAP does support booting from USB. It has an EFI folder so I believe it is using UEFI boot.Any ideas why the unRAID utility fails? I don't know enough about things at this moment to be able to determine what the differences are. I can do some investigating with a bit of guidance.If there is a way to replace the memtest86 install on the working USB drive? (maybe just rename the drive and copy over the unRAID files?)Thank you.
