i can setup the installer and install windows but when ever i install boot camp on the windows side rather than manually loading the drivers the windows boot no longer loads the os when starting the computer

the title says it all. first when i tried making my flash drive in boot camp on the mac OS side the drive would not be created because one of the windows installer files was larger than 4 GB than when i created the drive manually i grabbed the BC6 files from the apple website but when i run the BC installer on the windows side after installing windows on reboot the computer fails to load the windows OS and no matter what i do from there the windows os is corrupted and nothing will fix it. was wondering if there is something someone sees that im doing wrong or if someone has had previous experience with this. Oh and the computer i am running is a mac book pro mid 2012 with an i7 and 16GB ram and the intel 650m graphics adapter with an ssd as the hard drive in case anyone needs the specs.
