I'v been trying to dual boot windows 7 and CentOS 7 for a week now
without any luck.
CentOS 5/6 and Fedora 20 recognise the Windows installation and place
an entry for it on the boot menu.
CentOS 7 anaconda recognises the Windows 7 ntfs partition at
installation time as unknown but doesn't place an entry for it in the
grub2 boot files. Did you install CentOS 7 last.
