Install From USB

I am trying to install SLES12 sp3 on a Lenovo SR650 server.

I used Rufus to create a bootable USB drive. I selected DD image mode as suggested.

The only folder on the USB is EFI. The SLES12sp3 DVD 1 installation files are not there even though I selected them.

However the server says it cannot find a bootable device.

I have done the F12 one time boot option and set to legacy BIOS.

I'm not finding any documentation as to what could be wrong and am lost.

Any assistance is appreciated,

Thank you.

    Have another SLE or openSUSE system around, install imagewriter and use that..... AFAIK is a isohydrid so just dd should work.
    fdisk -l SLE-12-SP3-Server-DVD-x86_64-GM-DVD1.iso

    I only have SLES 12sp3 servers.

    I downloaded the .ymp file. Not sure how to install it from there.

    Thank you!

    I ended up using Etcher and my USB boots to the SLES install just fine.

    Thank you!!

    For the next time:

    1.) umount usb memory stick
    # su
    # umount /dev/sdb1
    # df -h

    2.) Write new msdos partition table
    # fdisk /dev/sdb

    3.) check partition table
    # fdisk /dev/sdb

    4.) install iso image on usb memory stick
    # dd if=SLE-15-Installer-DVD-x86_64-GM-DVD1.iso of=/dev/sdb

    => Deployment Guide => chaptre "2.4.1 Boot Media"

    5.) check partition table
    # fdisk /dev/sdb
