April 29, 20242 yr My UNRAID server has stopped booting from the USB Drive. When I startup the server, it boots immediately into BIOS. Inside the BIOS I can see All my HDD, SSDs, and the USB that contains UNRAID, but nothing is showing up as bootable. Any assistance with this matter would be greatly appreciated.
April 30, 20242 yr Community Expert Otehr bios option to edit and test: disable secure boot. turn on CSM and trun off uefi boot. Unraid boots form clasic bios first a check box needs to be enabled to allow UEFI boot once in. boot option override boot and select the usb thumnb drive.
April 30, 20242 yr Community Expert How are you booting (legacy or UEFI). you may need to redo the flash drive if it is not showing as bootable.
May 3, 20242 yr I've been having lots of USB issues since I upgraded my hardware and I'm just now realizing there has been a longstanding issue with Ryzen and USB. I'm starting to wonder how many USB issues on this forum are related to that.
May 3, 20242 yr Community Expert quite a few. I use a ryen b4550 setup and use a bestbuy pny usb. it is more to watch the ports, its best to use usb2 ports for boot with unraid. If you have an extra USB 2.0 motherbaord headed and want the flash drive in the case: https://www.digikey.com/en/products/detail/startech.com/USBMBADAPT/21398325
May 14, 20242 yr Author Solution The issue was a corrupted usb drive. It had nothing to do with boot settings. Correction was uninstalling UNRAID and installing TrueNAS. No more problem. Edited May 14, 20242 yr by D34dM0uth
