Detailed procedures are not possible without a detailed inventory of your environment.
PXE is my choice for new OS deployments, but not all tablets have PXE. Specifically what tablets do you have?
Some Tablets are also not able to run x64 OS. Do you have any Atom processor machines?
Installation works best when running from Ethernet, rather than Wi-Fi? What is your wired Network status?
Do your machines need to be domain joined? do you have procedures for imaging machines dis-connected from your corpnet?
