Can't boot Windows 7 without DVD in drive

Question

Is there a hotfix for this?  It's related to this thread: http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/64f729b6-d796-4030-82d9-3fe5a44b0180
If you go to www.google.com and search using the phrase "Windows 7 won't boot without dvd" you'll see that others have this problem too.
I have 2 Raptor hard drives in a RAID-0 array.
I have a third internal 1.5 terabyte hard drive.
The 1.5 terabyte (C:\) HD is for my Win7 OS & my programs.
The RAID-0 array (D:\) is for my games. (RAID-0 is for fast loading performance)
I think it recognized one of the RAID-0 drives as the "first hard drive attached to my motherboard" and somehow Windows 7 put the boot loader info on that hard drive, instead of my 1.5 terabyte C: drive with Windows 7.  As a result, Windows 7 won't boot unless I have the DVD in the drive. 
I tried the option to boot from the DVD, repair my computer, and from the command prompt do a "bootrec /rebuildbcd" but that failed.  So the only fix I see is to PHYSICALLY disconnect the 2 RAID-0 drives, and then do a full install of Windows 7 again.  What a royal pain-in-the-____.  My motherboard is an ASUS P6T.   Any hotfix in the works???

Answer 1

I finally fixed it.  When it first failed, all the research I found said to do the following (which didn't work):
1) Boot from the Windows 7 DVD
2) Click "Next"
3) Click the "Repair your computer" link
4) Choose the "Command Prompt" option in the SYSTEM RECOVERY OPTIONS menu
5) Type: "Bootrec /rebuildbcd" (without the quotes) and press ENTER
That supposedly should have fixed the problem, but it never did.  After doing this, I always got the following error message
(which seems like a success message) . . .
Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.
Now, it might have said, "the operation completed successfully", but it CLEARLY did NOT work!!!!!!!!!!!!!!!!!!! 
Identified Windows installations should be 1, not 0.
Then, I found an obscure message that had the answer.  It was on a message board, written in TINY little text.   Here's what I found:
If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.
Bcdedit /export C:\BCD_Backup
ren c:\boot\bcd bcd.old
Bootrec /rebuildbcd
So I rebooted and did the following steps.  This is the exact ENTIRE process I did, in case anyone else needs to follow these steps . . .
1) Boot from the Windows 7 DVD      (Yes, patience is a virtue!)
2) Click "Next"
3) Click the "Repair your computer" link
4) Choose the "Command Prompt" option in the SYSTEM RECOVERY OPTIONS menu
5) Type the following commands, exactly as written below, in the order in which they are presented, and press ENTER after each command:
Bcdedit /export C:\BCD_Backup
ren c:\boot\bcd bcd.old
Bootrec /rebuildbcd
Then close the command prompt box and re-boot your computer.  Make sure the boot order in your BIOS has the correct drive as your first boot device.  That sounds obvious, but computers give various devices very obscure names, and it's easy to choose the wrong number(device).  
Hopefully this process works for others, like it worked for me.  I no longer need the Windows 7 DVD in the drive to boot into Windows.  Wow, that only took me a full 8 hours of trial and error and research to figure out and fix.  Microsoft is making such amazing advancements in technology!!!  </sarcasm off>
Thanks for the offer of help derosnec.  It's much appreciated!
