I did the steps above (built a new USB Stick) and it is the same problem. Similar to you it booted eventually but took more than one try. The motherboard also has an LED status code. When it was not booting, it was reading various 40's values which I'm assuming was CPU temperature (normal behavior). It has booted now and it is reading FF while it is up and running. I believe FF is suppose to be a failed boot. Seems backwards to me so this is why I'm wondering if it could be a bad bios that I upgraded recently. I think this is unlikley Also more likely is a bad VRM or PSU. I unplugged everything from the motherboard and remove the drives from the psu to lighten the load on the PSU but the boot problems still persisted. I'm going to do some additional hardware testing, removing case plugs (usb mostly) from the motherboard since that could be causing a problem. I'm currently thinking it is going to be a new motherboard, CPU and memory (as my motherboard is old). Still thinking it through as it is up and running right now.

So I get a new USB stick, create a unRaid boot drive, and then copy the config folder from the old drive? Does that sound correct? Thanks for your help. Ron

I'm relatively new to unRAID and I have had unraid running for about 20 days. I had unraid set-up with and I was making some adjustments to my case (tying down wires, ...) I went to restart and the system would not boot. I get the message "Reboot and Select proper boot device or insert Boot Media in selected Boot device and press a key. I have read the USB drive in another system and it appears readable with no errors. I have tried several USB ports directly on the motherboard and that does not resolve it either. It makes it to what appears to be a grub screen. I tried all the options on the boot window. (Safe Mode, ....) but it will not boot. It does start to boot unraid but fails. I capture this with my camera. Loading /bzimage...OK Loading /bzroot...OK Loading /bzroot-gui...OK EFI stub: ERROR: exit_boot() failed! EFI stub: ERROR: efi_stub_entry() failed! These last two error messages are almost not visible as they are cleared so quickly. Then it moves to the Unbootable media message. I think my usb is corrupted somehow but not sure if there is any way to recover it.

I tried to format the usb stick to start all over again and it seems like windows does not want to fomat it. Likely a faulty usb stick.

Thanks seems like it is a bad usb stick. Windows will no longer format the usb drive "Can't find file."

I have a older system that I'm trying to boot from USB. The system is a MSi X97 Gaming 5, core i5 4690K with 16 GB of ram, an older graphics card and a 9207-8i PCIE3.0 6Gbps HBA installed (no drives). I created a boot image on windows using the unraid imager. The USB stick is a 32 GB microcenter usb (maximum allowable I believe). When I plug this into the motherboard usb slot, the system is unable to find and boot from the USB stick. I have tried creating this several times, also tried to change the BIOS settings for boot order. Validated a number of BIOS settings legacy usb support is enabled, fast boot is disabled. I have tried to manually create an image and I have the same problem. If I flash this USB stick with ubuntu 24 using balena etcher and put it in the same usb slot it immediately boots to the usb and gives me the try ubunutu grub entries. What am I doing wrong with unraid? This is supposed to be an easy process but it has taken hours of troubleshooting and nothing works.

I'm using an older system to try unraid. The system is a MSI z97 Gaming5 Motherboard with an i5-4690K CPU and 16 GB of ram. I have a 9207-8i PCIE3.0 6Gbps HBA card installed with no harddrives attached right now. I have been trying to boot using a USB. I first tried using mini SD card reader and a 16 GB SD card. I used windows to write the image and it did boot into unraid and I was able to get logged in. The USB drive was blacklisted and after some investigation I determined that this was because of the card reader and I really needed a usb stick. I found a 32 GB microcenter usb stick (which seems to be the max allowed) I wrote the image using the same Windows software, installed the stick in the same usb slot and now it will not recognize it as a boot drive. I have tried to write the image several times, ran the script to make it a bootable drive but no luck. Moved the usb stick to multiple different usb locations all on the motherboard (not the case usb drives). I have reviewed the bios setting, fast boot is not enabled, legacy usb support is enabled. I can't find anything like boot order of Forced-FDD, USB-HDD, USB-ZIP. I have a monitor attached and I can see the HBA card boot, it complains that it is not able to find a bootable drive then continues on. Then I get the BIOS message not bootable drive. I look in the BIOS I see one usb highlighted in the boot order When I look in the BOIS it is seeing the USB as a PMAP drive not a UEFI drive. Is that the cause of it not being able to boot? Is this because of the size of the usb stick, the make of the usb stick? If I use belana etcher to write ubuntu, the system boots from the usb stick. Maybe it is not the USB stick but the software that is writing to the usb stick? This is really frustrating as I have spent several hour just trying to get a working install.
