Windows 7: BOOTMGR missing on Triple boot system with GRUB...

BOOTMGR missing on Triple boot system with GRUB...

Hello Guys and Gals!
I have an interesting and puzzling problem here...
I have created a successful triple booting system with Windows 7,Ubuntu 10.10,and Windows XP. I did that BEFORE I just recently upgraded most of my hardware including my Motherboard,RAM (16 Gb up from 8),video card,processor and monitor.I am using GRUB 2 as my boot loader.Ubuntu is now clearly broken,as it does boot but now needs a partial upgrade ( considering upgrading all the way to 11.10 with all this new hardware...maybe ) and many updates. Windows XP does not boot however and gives me the old :
BOOTMGR is missing - press CTRL-ALT-DELETE to restart.
I have placed the hard drive boot priorities in the proper order so that the system boots to the GRUB flawlessly but I am lost on the proper method to repair XP in this configuration.

Let me describe what happens when I boot up and try to answer some initial questions.

When I boot my machine displays all the POST information as normal,then GRUB comes up showing my Ubuntu,Windows 7,and Windows XP options as normal. When I choose XP
I get the error. Windows 7 boots up when I choose it in GRUB with no issues what-so-ever.

I already have updated/re-installed all the new and necessary drivers ( for Windows 7 anyway )...Still have to work on Ubuntu...and
I am running XP because of an old program that requires it to run properly ( Dundjinni - don't laugh! I know a few of you still play Dungeons and Dragons ).

As I stated before my Tripleboot worked perfectly before the hardware upgrades so BOOTMGR being an element of Windows 7 makes sense as a symptom.

I also need to point out that Windows 7 lives on a WD Raptor 72 Gb by itself, that Ubuntu and XP share a 500 Gb WD, and there is a 1 Tb WD that both the other drives have access to as a data drive. The system boots from the drive that Ubuntu and XP are on via the GRUB.

Thanks in advance for any and all help.

Could I get the steps you used to set up the triple boot to begin with? I know in the past, I had to install everything in a certain order for triple booting 7, XP, and Linux to work out, so your installation order would give me an idea of how to help you resolve your current issue.

I had originally had Windows 7 installed on the raptor with the 1 Terabyte HD as the only other drive in the system.Then, I added the 500 gig drive and installed Ubuntu on it and was booting from GRUB successfully from that. Then I disconnected the Windows 7 drive...then made a partition on the 500 gig drive and installed XP there...then re-connected the windows 7 drive and GRUB picked it up just fine- easy peasy triple boot. Worked great for 6 months then I installed all the new hard ware and that is when my problems began.

Disconnect your Windows 7 drive. Insert your Windows XP disc, see Option Two of Description of the Windows XP Recovery Console for advanced users, and the recovery command you want is fixboot. Run fixboot, hit y when asked, and reconnect the 7 drive.

Post back whether this worked.

You'll need to run a XP Repair Install in most cases to adjust XP to new hardware, if the boot repair commands alone don't work. Unplug the Windows 7 HD during these operations.

Once XP starts plug back in Windows 7 HD, mark Windows 7 Active, power down to unplug the XP/Ubuntu HD, then from Windows 7 DVD Repair console or System Repair Disk run Startup Repair up to 3 separate times to write or repair the System boot files so it boots on it's own.

Then set Windows 7 HD to boot first in BIOS setup, use one-time BIOS Boot Menu key to trigger XP HD to boot. This keeps the HD's independent to come and go as you please and safeguards Windows 7 from GRUB corruption.

Then add Ubuntu following these steps which are easiest: Dual boot Ubuntu-Win7
