You could always boot into the Windows Recovery console if it is windows
2000 or XP and run fixmbr and fixboot. This will verify that you have a
correctly working boot sector for Windows.
Then you will need to boot into recovery mode off of a CentOS cd and run
grub-install.
This has worked for me in the past.
