[Centos] GRUB Bootloader

I installed CentOS 4 Beta on an ATA disk to have a look at it, and on the same computer I have a Windows installation on a SATA disk. In the CentOS installation process it could see the operatingsystem on the SATA and everything looked good, it said something like "Other... /dev/sda" (not quite sure, it looked right so I didn't really take note of it).

Now when I want to boot the windows installation is is attempting to boot from /dev/hdd, and that disk isn't even there?

I had CentOS 3 on the ATA disk before and there it did the same thing, it's not a big problem as I just have to hit Esc and select the SATA before it starts booting, but shouldn't this be corrected somewhere?
