I am at wit's end!
I have a brand new out of the box Dell R730xd. I am simply trying to install / boot Centos 6.7 onto it from a USB stick.
I have downloaded (to my Mac) 3 flavors of Centos-6.7. minimal / LiveCD and DVD.1.bin. I used various techniques to burn the USB Stick but basically was
-- hdiutility to do a convert from iso to .img file (I have done this and NOT done this) -- dd file to usb stick
When I put the stick in the front of the R730xd and boot -- I hit F11 and add the USB to the "One-time UEFI Boot Options".
However, not matter what I try -- I always get a
Boot Failure: Boot from Front Device DISK2: USB DRIVE
Boot Failure: Make sure a compatible media type is installed.
I have looked at every imaginable BIOS / UEFI BIOS option ..
I am pulling my hair out -- this can't be that hard.

P.S. I did check the RAID card to make sure my 2 SSD's are already configured as RAID-1 in case I ever do get to boot it and install the OS.
