Trying to boot from a USB on a Dell PowerEdge T110-II

I have the ISO for Server 2012R2 essentials.  I want to install it on a Dell PowerEdge T110-II

I put the ISO on a bootable 8GB USB stick.

I can boot off the USB on a vostro 200 I have. So that makes me think I did the ISO to USB correctly.

2 things -

1) depending on boot mode, I either do or don't see the USB stick (see attached 2 pictures).

2) when I do see the USB and boot off it, I get a message:

Boot failed
Please ensure compatible bootable media Is available.
Use the system setup program to change the boot mode as needed.

You may need to disable UEFI / Secure boot temporarily and change the boot order to put USB at the top.

We did this to boot a Lenovo Server from DVD.

Looking at the screen shot, it appears that you haven't select the boot order. You need to select UEFI boot mode. Try the below method and see it helps;

Enter in Setup or select F11 Boot Manager during Dell logo

Find Boot mode UEFI, GOTO  UEFI boot menu there will show the bootable options

Identify the UEFI boot Option Maintenance and select "Boot From File" and navigate to efi \ Microsoft \ boot \ cdboot. uefi or efi \ Microsoft \ boot \ cdboot. uefi

So with UEFI enabled Boot Option will list the available UEFI boot paths (v's boot devices). If a system has never had a UEFI boot path available and no pre-defined UEFI boot path/devices installed, then no items will be shown in the Boot Sequence.
If a storage device  has a pre-defined UEFI boot path by The “UEFI the “Add Boot Option” then entering the “Boot Option Name”, “File System List”, and “File Name”.

Hope this helps

Thanks John.  I haven't dealt with UEFI much.  My perception is that it can be more troublesome than BIOS.  Interesting that I can see the USB only when it's set for UEFI.  I know I've had to 'play' with the boot settings when trying to repair win 8 machines.  I don't see many settings on this machine to disable secure boot or other UEFI things.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

So then as your server is, set USB to the top of the boot order.

Also consider making the image onto a DVD and booting from the DVD. I have done this, not USB boot on a server.
Radhakrishnan RSenior Technical LeadCommented:

You can try the method which i posted earlier. Also, as John said, you can write the ISO into DVD and boot from it which is much easier than USB boot.

Thanks Radhakrishnan

I went into boot from file and get a file explorer page showing 2 entries for the PERC controller (as it came from Dell with no OS installed) and embedded NIC 1.

Nothing from the USB stick.  Your last paragraph talks of that, I think,   But not sure what to do at this point.  Tips?

"If a system has never had a UEFI boot path available and no pre-defined UEFI boot path/devices installed, then no items will be shown in the Boot Sequence.

It means the boot files aren't available. Either the USB won't support or you wouldn't have prepared the USB as bootable.

Call Dell Server Support. They should supply DVD and so they should be able to tell you how to boot from DVD.
DELL servers usually come with an OpenManage DVD, and that is used to setup the server and install your OS. Just boot from the OpenManage DVD then follow the options you have. It should be able to install an OS directly from an iso file.

Rindi - oh yeah, I have that DVD 'OpenManage System management tools and docs v 8.1'  but it says 'this is not a bootable dvd'   : (

I have a Zalman USB device that lets you store ISOs and choose which you want to boot from.  I am into the setup at this point that way.  

Thank you all.  

Some other questions:
Then look for another DVD, there should be one that is bootable (unless Dell, like HP has moved to some other tools, like Smart provisioning, where everything is built into the firmware, but then you should also boot directly into that ).

After many hours I found the hidden solution:

• Insert Bootable USB Flash Drive
• Turn on Dell PowerEdge T110 II
• At Dell splash screen press F11 to select Boot Manager
• This is the trick, in Boot Manager select Harddisk <Slot 1 RAID: #0100 ID4F LUNO Dell Virtual>
• The next screen will be the option of USB Flash Drive or Harddisk. Select USB Flash Drive.
