January 12, 20251 yr Got a Threadripper system that's kinda spare and I want to try out Unraid 7.0. My plan is to trial Unraid using the free 30 days thing. I've tried a bunch of different USB sticks, but every single time when I try to boot from the USB drive, I get: "Missing Operating System. Reboot and select proper boot device." It's picking up the right USB drive. I'm using the official Unraid USB creator and I'm not changing any default settings. I've even tried running that "make_bootable.bat" file when the USB is created. Motherboard is running the latest BIOS. CPU: AMD Ryzen Threadripper 1920x MOTHERBOARD: ASRock X399 Taichi RAM: 32GB DDR4 (2x 16GB) What am I missing here?
January 12, 20251 yr Community Expert I guess you need to enable UEFI boot This needs to be enabled on the Stick. Put the stick into a windows computer or something. In the main directory you will find a folder called "EFI-" rename this folder to "EFI" (without "-") This should allow you to boot in your target machine. Try it out.

Nope, no folder listed as 'efi-' See attached screenshot.
January 12, 20251 yr Community Expert Ok, so EFI is already activated. Look into your BIOS settings for "Secure Boot". Should NOT be set to "Windows" but to "other operating systems". (Sometimes you also need to play around with CMS or something alike. Sadly all BIOS' are different, no way to tell the exact topics for your device) Edited January 12, 20251 yr by MAM59

(Sometimes you also need to play around with CMS or something alike. Sadly all BIOS' are different, no way to tell the exact topics for your device) Secure Boot has always been disabled. CSM was enabled, I tried disabling it but then it didn't pick up any bootable drives. For my BIOS, I don't get any options like that for Secure Boot. I've just enabled it and cleared / reset the keys, I'll try saving these settings.
January 12, 20251 yr Community Expert UEFI needs Secure Boot to be turned on. Is the stick shown in Bios? Some Boards have additional USB ports that are not allowed for booting. The stick should show up and usually there are also "boot overwrite" settings that allow you to boot from the stick manually (just for testing until you get the correct settings).

Not something you've suggested but something else. Get back to you.

Ok, that didn't work A) Had an old USB 2.0 bracket. Plugged that in and ran the USB from that, but I still get the error B) With Secure Boot enabled and the keys installed, it doesn't pick up any bootable drives
January 12, 20251 yr Community Expert Ok, stomach full (brain not. lol)... Lets start the other way round, maybe the machine is too old for current UEFI. (There is currently a switch going on, BIOS older than 6 months may not work anymore). * turn off secure boot (the "EFI" Folder is not used then anymore) completely * turn on CSM with booting from legacy devices * use an USB-2 port for the stick (this is mainly to save electricity and to keep it cool. It will live longer this way) * try to boot from the stick

January 12, 20251 yr Community Expert just searched the web a bit.... Your board really seems to be picky with secure boot & Co (has nothing to do with UNRAID). Maybe you should read some comments on Reddit and so on and get more info how to get it to work. First start seems to be to clear cmos and start all over. maybe this can help ? https://www.asrock.com/support/faq.de.asp?id=531 Edited January 12, 20251 yr by MAM59
January 12, 20251 yr Community Expert Try the USB 2.0 ports (front ones should be OK) or maybe certain USB 3.0 ports, some of the USB3.0 ports don't come online properly until later in the boot process. Historical reference 😆
