July 6, 2025Jul 6 I installed unraid new because I bought an prebuilt server but I want to go back to unraid.I installed unraid on my usb drive (8gb) with the windows app and made it bootable but if I plug it into my server it shows non bootable devices and if I choose the drive in the bootmanager and try to boot it it shows non bootable devices found
July 6, 2025Jul 6 Community Expert Are you trying to boot in legacy or UEFI mode? If UEFI mode have you made sure that the EFI folder on the flash drive does not have a trailing '-' character?If trying to boot in legacy mode have you tried formatting the flash drive with something like Rufus and setting it to be bootable there? Sometimes that seems to work better than using the USB Creator tool to do the formatting.

As long as the folder is simply named 'EFI' then it should be bootable in UEFI mode. When you go into the BIOS does it show the drive as bootable into UEFI mode? If not are you sure your motherboard supports UEFI mode?

July 6, 2025Jul 6 Author Solution I got it You have to install unraid with an zip file and you have to format it to mbr that you can use uefi and bios. You should boot your server/ pc with secure boot off
