Hi,
I have a problem running / installing Unraid on a Minisforum HM90 Server. I installed Unraid on a USB Stick. The Ports on the back of the Server doesn't recognize the stick at all. In the front the stick works. At least it shows in the BIOS. But I can't boot from it. When I'm in the Boot Menu (as you can see on the photo), I see, that the stick is bootable. But when I try to boot, the screen goes blank for a second and I'm again in the boot menu. 
Somewhere I read, that it might be the IOMMU Setting in the BIOS. I turned it off, but same. I also tried different settings for USB. Harddrive or CDROM. Same result. 
What can I do?
 
EDIT:
I also tried a different USB Stick (Sandisk) and created the Stick with a Mac instead of a Windows 11 Machine, like I did the first time. Same result. 
 
 
EDIT / SOLUTION:
 
I had to rename the EFI- folder on the USB Drive to EFI. After I did it, I was able to boot Unraid.
