I would be concerned about the status of the hard drive. The Boot Manager will not appear if there are no bootable volumes discovered. This suggests that neither volume on the hard drive were discoverable as valid startup volumes. That in turn suggests a problem with the drive's RDB where the partition information and boot sectors are stored.
What I would do in your shoes is backup both volumes then repartition and reformat the hard drive. Use Boot Camp Assistant to make your Windows volume, then restore both backups.
Already foreclosed. Because:
A): the Mac OS volume was always intact (the Win Install-DVD can only repair the Win Partition)
B): the Mac OS Install-DVD wasn't booted too (but is ok)
C) other Mac OS Startvolumes on external harddrives wasn't booted (but are ok)
So if the startupmanager weren't showing up because all volumes were damaged, than why is everything fine after repairing the windows volume? No no! The problem is the startupmanager.
No, this is a Windows issue.
If you move the Windows drive to another drive bay; if you (make the mistake of putting Windows on the same hard drive) and move it.
Never a good idea to put both on the same drive, not when you have a Mac Pro.
Windows DVD does a good job and has its own system recovery features also.

I haven't moved the drive.
Aside from that, how should i install Boot Camp on another drive, seeing that the Boot Camp Assistent only lets me prepare a volume for Windows-Installation on the same drive i booted from! Explain how to bypass this problem.

It may partly. But it is related to the Firmware of the Mac (EFI).
When you use Boot Camp Assitant, and I said it isn't needed with Windows 7 if you install on another drive, it does give the option to format a drive.
http://www.apple.com/support/bootcamp read the pdf and articles and look. Most of us with Mac Pro do not use Mac OS drive for Windows.
I've been using Vista on Mac Pro for over 4 yrs, and Windows 7 for over two.
Why do you want to blame UEFI? dont bother.
10.6.6 did make it worse, not sure why, longer boot times for both OS X and Windows, and for some people minutes longer.
All Apple hardware is presently EFI 1.10, not UEFI. There are some pieces of UEFI 2.x Apple uses such as GOP instead of UGA on newer hardware (last couple of years). But it's still not UEFI 2.x compliant.
Windows 7 only groks BIOS and UEFI 2.x So your only option on Apple hardware is BIOS. In order to ensure BIOS emulation is used, instead of EFI, the disk needs an MBR, not GPT.
Bootcamp, on disks that are used for both Mac OS X and Windows, creates a hybrid MBR+GPT disk. It will act as GPT for Mac OS, and MBR for everything else.
If you are not going to install Mac OS on your extra drive, then you do not need Bootcamp at all. Just boot off the Windows DVD, point it to the extra drive and have it partition and reformat it (MBR + NTFS) and that will work.
This situation is a problem for > 2.2TB drive support. I'd like to see Apple at least give us the option to abandon BIOS entirely, and give us a fully compliant UEFI 2.x firmware.
One other thing. MBR only supports 4 primary partitions. I don't know how Bootcamp negotiates this if a GPT disk has 4+ visible partitions (one partition, the EFI system partition is hidden. I'm not a big fan of the hybrid MBR+GPT partition. There aren't many tools that understand how to manage this, probably the best one is GPT fdisk (gdisk). You won't find Disk Utility, Tech Tool, Disk Warrior dealing with the partition tables or syncing them if they are hybrid MBR+GPT. They deal only with what they know which is the filesystem (volume format), the part inside each partition.
