Bootloader options
There are a few options:
1. Continue to use Windows Boot Manager (ntldr). However, it's probably not a very good idea because Windows Server 2003 might start complaining. But if you want to try, take a look at this.
http://www.freebsd.org/doc/en_US.ISO...#NT-BOOTLOADER
If the FreeBSD installation is on the same hard disk with Windows, copy /boot/boot1 to your windows partition. You can rename the file if you want to. Then put C:\BOOTSECT.BSD="FreeBSD" into boot.ini. However, if you have it on a different disk **DO NOT** use /boot/boot1 or /boot/boot0. This would wipe out the partition table in your hard disk. I had accidentally done it before and I wasn't able to recover the partitions. Instead you can do:
# dd if=/dev/ad?s?? of=/bootsect.bsd bs=512 count=1
Change ad?s?? to the appropriate device node. The device for the first hard disk, first partition, first slice (FreeBSD partition scheme), is ad0s1a. Then modify boot.ini, and it should work. This command copies the first 512-byte block from the device you specified to the output file (in this case bootsect.bsd).
2. Use your BIOS. Some computer has BIOS that allows you to choose what device to boot after POST.
3. Use the default FreeBSD bootloader. However, the bootloader will display ??? for ntfs partitions.
4. Use GRUB (GRand Unified Bootloader).
http://www.gnu.org/software/grub/
If you want to install it through FreeBSD, download the precompiled package from the FreeBSD ftp site. It's under the sysutils category. Use pkg_add to install the package and configure the loader. Documentation is on the GRUB web site. In my opion, this is the best way. Windows won't complain it's not the only OS on the computer, and it can boot almost any OS through chain loading. Also, it provides a very nice screen at start up and very flexible.
If you have any questions, just post it to this thread.
I hope this helps you. Good Luck!

installgrub
installgrub(1M) installgrub(1M) NAME
installgrub - install GRUB in a disk partition or a floppy SYNOPSIS
/sbin/installgrub [-fm] stage1 stage2 raw-device The installgrub command is an -only program. GRUB stands for GRand Unified Bootloader. installgrub installs GRUB stage 1 and stage 2 files on the boot area of a disk partition. If you specify the -m option, installgrub installs the stage 1 file on the master boot sector of the disk. The installgrub command accepts the following options: -f Suppresses interaction when overwriting the master boot sector. -m Installs GRUB stage1 on the master boot sector interactively. The installgrub command accepts the following operands: stage1 The name of the GRUB stage 1 file. stage2 The name of the GRUB stage 2 file. raw-device The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable. For disk devices, specify the slice where the GRUB menu file is located. (For Solaris it is the root slice.) For a floppy disk, it is /dev/rdiskette. Example 1: Installing GRUB on a Hard Disk Slice The following command installs GRUB on a system where the root slice is c0d0s0: example# /sbin/installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0d0s0 Example 2: Installing GRUB on a Floppy The following command installs GRUB on a formatted floppy: example# mount -F pcfs /dev/diskette /mnt # mkdir -p /mnt/boot/grub # cp /boot/grub/* /mnt/boot/grub # umount /mnt # cd /boot/grub # /sbin/installgrub stage1 stage2 /dev/rdiskette /boot/grub Directory where GRUB files reside. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ boot(1M), fdisk(1M), fmthard(1M), kernel(1M), attributes(5) Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always boot the GRUB in the Solaris partition regardless of which fdisk partition is active. 24 May 2005 installgrub(1M)
