Hi12 Z8300 Dual Boot Windows Files, BIOS, and Drivers

Hello! I have reviewed the other topics regarding reinstalling windows, and I was unable to download the windows files. I could cobble something together, but I am hopeful that someone can post all of the files I need. I have a Z8300. Serial Number Q64G45161002246. Model CWI520. I appreciate the help! Any information on installing windows only, not reinstalling Android, are also appreciated! Thank you!
