I have a new Dell R440 Server on which I need to install Win Svr 2012 R2.
I have the iso file on a file sever which is connected to the same switch.
The server takes forever to boot up to the virtual media and when it does and the OS installation begins, the copy process is again very slow.
It then fails after reaching about 10 %.
I am trying now to boot from a USB key which i made from the iso image using Rufus, but it says it failed to boot from USB device.
Do see attached picture.
My question is: is there a particular bios setting or other settings that i need to configure before I could be able to boot from the USB key?
Also, what possible reason could there be for the slowness i am experiencing when booting from the Virtual Media (iso located on file server)?
