yes I know its common practice but i think you are misunderstanding and never read the question carefully
for a server/computer that HAS NO PHYSICAL ACCESS TO THE DVD.... I need a way to be able to restore/reinstall Windows from a HDD that contains the ISO image. This is a remote server I am referring to where I manage the server myself.
lets re-write the question clearly:
How can I install Windows or run setup, from the HDD directly, that has no access to DVD nor is it possible to connect an external drive to it.
Lets say C:\ fails or i format it or whatever.
I have KVM IP. I want to be able to use either a small ISO which I can direct via KVM IP to use and boot the system from which will in turn allow me to install windows from another physical HDD which is on the server
Allow me to access that partition to run setup.
