Install of SQL Server 2014 SE
You could look into slip streaming the installation. 

In order to slipstream the updates:


Download the necessary updates and store them in a location that you have access to (local or UNC path is fine).
Recent updates are just the .exe file; older CUs were compressed, so if necessary extract the files
open cmd
change directory to the root of the installation media
start setup.exe from cmd spcifying the necessary switches


Setup.exe /Action=Install /UpdateEnabled=TRUE /UpdateSource="updates path"



If this is something that you are likely to do regularly, it is possible to re-package the iso with these updates in.


Extract ISO image using a utility like 7zip or mount and copy to a directory
Create an updates folder on in the root of the extracted media
Copy in the required SP/CU
Recreate the ISO image using any iso image creator such as MagicISO


To use the slipstreamed files, open cmd and run similar to before:

Setup.exe /Action=Install /UpdateEnabled=TRUE /UpdateSource=".\updates"
