November 11, 20214 yr Swapped ancient board for a new ASUS PRIME H570M-PLUS/CSM, unRAID USB from old server will not boot, made a new one, same issue. Put Win11 on a third USB stick and it boots perfectly. I have spent the past 4 hours changing every single boot setting in the BIOS that the docs (or Google) suggest without luck, it always just boots into the BIOS. Anyone able to throw out a lifeline here, I'm kinda tearing my hair out.
November 11, 20214 yr Community Expert Solution If you are booting UEFI, there is a folder on flash that must be named EFI If you are booting legacy, that same folder must be named EFI- Boot from USB2 port.
December 18, 20214 yr Community Expert OMG - I been fuxing around with a new PC and trying to get my flash drive to work for the last 6 hours. Had a perfectly working machine but needed to expand storage so went from I7 from 2012. Moved all the drives 6x14TB and 2 10TB in a new AMD & Fractal Meshify 2XL case and Windows, Linux booted from flash but unraid did not and I checked all the settings.. SVM was ok but the issue was the old machine EFI- and i had to change to EFI then it booted. I luckily found this message, tested on another flash doing custom from the unraid creator setup and it Viola! There was no USB 2.0 on the board only 3's. I was going crazy! Now it's booted up and fine. This freaking fly's with this AMD 3700 compared to the 2012 I7-975. I even started looking online (but all deliveries seems to have delays now) to get a USB 2.0 addon card. Trurl - THANKS FOR THE INFORMATION.

December 19, 20214 yr Community Expert Yes, but It's resolved. The trick was renaming the EFI- to EFI and it booted up correctly. Only issue now is with the temps inside and fan control in unraid not working but thats a different thread.
November 17, 20232 yr @Cosine I also had the issue of the my new ASUS motherboard royally ignoring my unraid USB key when booting... (and sometimes recognizing it just to ignore it on the next reboot). I tried different USB keys, changing all the wrong UEFI settings (CSM compatibility, etc...), using all USB ports, especially USB 2, "EFI" vs "EFI-"... none of all that made a difference... I also pulled my hair out... way past the 4 hour mark... but finally found the culprit after 2 days: In ASUS UEFI BIOS, you want to DISABLE the "Fast Boot" (it's enabled by default). Mind you, there is zero noticeable difference in boot time, but it now recognizes my USB boot key every time. For reference, to be clear: EFI boot works fine, all USB ports ( 2.0, 3.0, 3.1, 3.2 ) work fine. (I think the solution accepted before should be untagged to avoid confusing future users of ASUS motherboards). Edited November 17, 20232 yr by fplanque Added more details about everything I tried
February 11, 20242 yr I replaced an old Gigabyte GA-X58A-UD3R with an ASUS Z730-A. Disabling fast boot wasn't enough to fix the startup issues, I also had to rename the directory from "EFI-" to "EFI" in order to get it to start on Unraid 6.12.6.
