BCDBOOT failure when attempting to copy boot files (and an operating system wasn't found

If you, like me, tried to deploy Windows8 (maybe for 7 is the same) using a wim image and then used the command

bcdboot c:\windows

and you got the message "failure when attempting to copy boot files" probably you are in the situation I was.
I tried to solve using this command:

bcdboot c:\windows /s s:

(where S: is the small system partition) and apparently with success, but after rebooting the machine you got:

An operating system wasn't found. Try disconnecting any drives that don't contain any operating system.

after many unsuccesful test and many investigation, I arrived to the conclusion the issue is related to the UEFI support of the machine (also if when starting, it appears to be a normal BIOS)

so I solved the issue with the command :

bcdboot c:\windows /s s: /f ALL

that ALL means copy both the BIOS and UEFI files to the disk

Remember S is the system partition, not the partition containing windows files
