A platform for remotely installing an operating system on a client machine includes a builder engine, for instance running on a support server. The builder engine may interrogate a remote client, for instance a diskless thin client or a machine having a disk but malfunctioning, and receive a machine state image from that machine. The builder engine may then assemble a customized image or kernel of an operating system such as Microsoft Windows™ for transmission to the client. A file system may be initialized in electronic memory, or otherwise and the machine may commence operation, without having executed an operating system setup process. In embodiments, the client machine may then link to a complete image of an operating system to reinstall a comprehensive version of that system, or perform other tasks.
