September 23, 2025Sep 23 Hi there guysSo I have three perfectly running Unraid systems and figured I may as well setup my personal server with Unraid as well. So I first did the installer and let it make the flash drive (Sandisk Cruizer Blade 32GB) - same drive I use for my other installs.It made it just fine and I took it to boot up, and nothing I have tried or done gets the PC to allow it to boot into that drive (same drive has been tested with TrueNAS Scale & Linux) it will just keep saying there is no operating system to boot into.I tried the manual method, same story. Nothing has happened like this before, all 3 other servers were as painless as I could have hoped for but nothing I try gets this one working. Motherboard is a brand new Gigabyte GA-B550-GAMING-X V2 B550 Gaming X V2 with a Ryzen 5 5500. Honestly I am just really tired now. I was hoping to not have this kind of problem with Unraid. Can anyone shed some light on this problem please. Edited September 23, 2025Sep 23 by Gokuofuin Solved it.
September 23, 2025Sep 23 Community Expert Have you made sure the 'EFI folder on the flash drive does not have a trailing '-' character? This is needed if booting in UEFI mode which may be all a new board supports.

September 23, 2025Sep 23 Community Expert Is it being seen as a bootable drive at the BIOS level? If not check it is formatted as FAT32.

September 23, 2025Sep 23 Community Expert If you are booting UEFI you just need to unzip the files to a FAT32 formatted flash drive, and it should boot; no need to run make bootable or do anything else. If it doesn't, either the board is not booting from that device or there's some compatibility issue with the flash drive/board/Unraid. See if the same flash drive boots in a different PC, or a different flash in that one.

Then I tried a random Sandisk Cruiser Blade 16GB I had in my bag and it worked just fine. So apparently the Sandisk Cruiser Blade 32GB is incompatible with Unraid. I say that because I was just running TrueNAS on it fine and also Ubuntu. So there we go.Thanks all for the assist! Cheers!
