executing, by the electronic device, an input/output system to initialize a communications element of the electronic device; and

issuing, by the electronic device, the request instruction after the communications element is initialized.

9. The boot image cloud deployment method according to claim 7 , further comprising a boot image obtaining method, comprising:

compiling and assembling a plurality of pieces of source code corresponding to the electronic device into the object files;

randomly arranging the object files;

establishing link addresses corresponding to the object files; and

obtaining one of the boot images.

10. The boot image cloud deployment method according to claim 7 , further comprising a boot image obtaining and verifying method, comprising:

compiling and assembling a plurality of pieces of source code corresponding to the electronic device into the object files;

randomly arranging the object files;

establishing link addresses corresponding to the object files;

signing the boot image by using a private key to obtain one of the boot images; and verifying the received boot image by using a public key and executing the boot image, wherein the public key corresponds to the private key.
