Check points for fixing missing boot-manager:

Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair".
Boot Manager is compressed
If by accident having compressed the entire boot partition, then Vista will display the following error:
BOOTMGR is compressed. Press Ctrl+Alt+Del to restart
OR maybe try this first.
Check points for fixing compressed boot-manager:
Boot into Windows Recovery Environment (WinRE) and perform a "Startup Repair".
If the above doesn't solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press "Load Drivers" (Instead of "Next") and use the mini Windows Explorer to right-click the boot-drive and deselect "Compress this Drive" and choose Apply to sub-folders and files.
If that also fails then boot into WinRE again, and go to the "Command Prompt" and execute these commands:
compact /U C:\bootmgr
compact /U C:\ntldr
If you for some strange reason have lost your Vista DVD, then you can also use a Windows 2000 / XP install CD and enter the recovery console instead and execute the following commands:
attrib -c c:\bootmgr
attrib -c c:\ntldr
Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

DO NOT ACT until these details are confirmed. I have worked on many dual boot machines in my day -- however I never deleted the boot partition of a dual boot machine. What is the ultimate goal for this machine a single boot windows 2003 server or something else?
Dual boot machines are tricky as Vista was the first operating system on the machine I believe the option to boot the windows 2003 server partition was added to the boot.ini file in the Vista Partition -- assuming Vista maintains that tradition from Windows NT. If you want I could research the reconstruction of boot blocks, etc.
The repair would probably involve at a minimum using a partitioning program on bootable media to flag the Windows 2003 partition as the boot partition. What is required beyond that will require research.
Another option could be to install a third party boot controller such as System Commander which recognised operating systems in existing partitions and enabled them as a boot choices. That might be most viable only if you are considering adding another operating system to the machine to allow system commander to be installed. (similarly the boot.ini entry could be added after installation of a windows nt based operating system too)
A DOS boot disk with system commander on it may allow access to the Windows 2003 system as a work around but who has dos around anymore with an appropriate version of system commander for dos that would recognise windows 2003?

I'm assuming that you are running vista. Try one of the following:
You will require a Vista DVD to boot off of.
Proceed to the System Repair Option, and follow the steps. It should repair your boot sectors..
Or
Once you have booted up, Press SHIFT+F10 to run 'cmd' prompt.
Then at the command prompt type the following (hitting <enter>) after each line.:
attrib bootmgr -s -r -h
del bootmgr
ren temp bootmgr
attrib bootmgr -a +s +r +h
