Hi all,

 

After more than ten years, my old Unraid setup's motherboard gave up the ghost and I decided to do some investing and bought myself a very recent Asus Intel B760M-A D4 (DDR4 mobo) combined with an Intel 13500 CPU.

 

It's been years since I've browsed a motherboard's bios, but I see lots has changed.  For one, I can't seem to find how to boot UNRAID from the USB thumbdrive, because the USB stick doesn't show up in the boot menu! 😵

 

I've already found this tutorial by Asus, but it's no good to me because the BIOS is different.  This video says to disable secure boot, but I can't find such an option!

 

The stupid part is the BIOS does see the USB stick, since I can update the BIOS from it.  Worked perfectly.  It also shows the thumstick's name in one of the menu's.  It just doesn't show up in the boot menu so I'm stuck.

 

I got a feeling that I just need to turn on some legacy option of some sort, but I can't seem to find it. 

 

Could somebody please help?

 

Thanks!

On the flash drive rename EFI- to EFI  and try again.

That worked!   👍

Thanks a million!  😁

(I feel stupid now)

Ok, I am in the same boat, I can find the secure boot issue just fine, but where is the EFI- located on the drive?

 

It's in the root of the flash drive.

thanks working now on gigabyte b760 motherboard.

 

Just did an upgrade & fix above still works, so thanks!

 

But does anyone know why EFI- vs EFI made such a difference? 

 

I upgraded my Mobo, CPU, and RAM. Worked perfectly on the old hardware with EFI-. 

Old board was booting legacy/CSM, new one is trying to boot UEFI only.

When the computer starts,  it runs several tests and initializes things, traditionally the BIOS did this, but these days there is a new system called UEFI, this is also designed to boot from various sources, and it looks for the EFI folder. If it is named differently like EFI-, it won't be found, and so can't be used to boot from.

Just wanted to let you guys know that I just ran into the same issue and it fixed my issue , oh my god, thank you !
