Did your centos install work?  Normally dual-boot systems bring up 
windows with grub in the mbr and a chainloader entry to load windows. 
Even if you are usb-booting centos, you should be able to set it up to 
chainload the boot to the windows partition on the hard disk as an 
alternate grub entry.  I'm not sure how this will mesh with disk 
encryption, though, but if a standard windows mbr would work, this might.
