[SOLVED] Unable to boot Unraid

[beans_everyday]

Hello there,

I have been running Unraid on my server for about two years now and today I tried switching to Unraid on my desktop computer.

When I choose the Unraid USB flash drive from my motherboard's boot menu, the screen goes black for one second and then sets me back at the boot menu.

 

My hardware:

• MSI B450 Mortar Max (BIOS ver. 7B89v2C, 2021-02-01)
• AMD Ryzen 5 Pro 4650G
• AMD RX 5700 XT
• AMD RX 550
• SanDisk Cruzer Fit 16GB USB 2.0 (same model that works fine on my home server)

 

Things I have tried so far:

• reflashing the USB drive, both with the Unraid installer and the legacy method (on Windows 10 as well as on Arch Linux)
• different USB ports
• different USB flash drive
• booting with and without dedicated GPUs installed
• disconnecting all SSDs
• booting with a Ryzen 5 3600 + dGPU

 

I spend all day trying different hardware combinations and BIOS settings, without success. I'd be thankful for any suggestions.

Do you have the USB stick set up to support UEFI boot (I.e. no trailing ‘~’ on the EFI folder)?  I have seen the symptoms you describe on some newer systems unless you boot in UEFI mode.

Hey, itimpi, thank you for your quick response!

The EFI directory's name was indeed the failure. I feel kinda dumb, but the system is running now. Thanks, again!

 

So, to clarify: I had to rename the folder EFI- to EFI.

Yes - that is required to be able to boot in UEFI mode.

Resurrecting an old one. Itimpi, you are awesome, just upgraded the brains and was not on UEFI before. 
 

This worked a treat.
