Try re-installing grub to the boot sector.  The simplest way to do this:

1. Boot into rescue mode using your install CD, by typing "linux rescue" at 
the boot prompt.
2. Execute "chroot /mnt/sysimage /bin/bash" to chroot to your CentOS 
install.
3. Execute "fdisk -l" and note the name of the disk where you see your OS 
partitions.  Since this is a laptop, it's most likely /dev/hda, or 
perhaps /dev/sda.
4. Run "/sbin/grub-install /dev/hda" (or sda).

Reboot, see what happens.  I've made a lot of assumptions, so if any step 
fails, report back.
