As you can see (and that's your case) it can use the MBR on one disk (disk 2) and loads a boot loader on another disk (disk 0, partition C:)

If you try a boot repair with disk 2 attached, it doesn't find anything wrong. That is why you must disconnect all other drives from the MB (Disk 1 & 2) leaving on only disk 0.
With only disk 0, it wont find a MBR set on disk 0 and it and will do a boot repair. (set it Active)
Then you have to clean the MBR of disk 2, making it non active.

If you try by commands you can make a mistake, By Boot Repair from Win 7 installation disk it's a safe procedure.
Ive already tried the Boot repair using the rescue disk with only disk 0 connected. It does not see the OS and when that happens the only option is to use the command line but it is not accepting the commands(i.e.- bootrec /FixMbr - bootrec /FixBoot - bootrec /RebuildBcd - bcdboot c:\windows /s C:) I was previously familiar with the command line. That was a long time ago. I know the correct commands but I still may be doing something wrong .... i.e. syntax, spacing, etc(if you check the screenshots above, it is not accepting them)I have asked several times. Is the fact that the C:/ drive is not marked active causing this. I also asked if marking the C: partition Active before the boot is fixed can cause a problem that cant be reversed. I am hoping that marking C: active will somehow solve the problems I am having without causing more problems or something that cant be reversed. I am not in a rush because everything is 'working' now and I just want to be cautious. But I really need to figure this out so I can make a backup. I REALLY appreciate your time and advice.... I just need to understand a few things(in red) beforehand. Thanks Mega and Paul

**** this is not important unless things go south but I would like to know if it is an option ..... can I take a Backup of the current C:\ drive as the boot partition and do a fresh install of Windows on that drive except now with a 100mb ‘system reserved partition’ then restore the Backup of the C:\ boot partition. The only problem I can see with that is the C: partition size will decrease after adding the 100mb System partition and the old C: may not transfer. I do have mini tool to resize the partition but it wants to put the system partition at the end(not sure if that matters).
Again thanks for your advice and any answers.

Not yet..... I promise I am not trying to make this hard but I have asked the same questions several times without getting definative answers..... if marking the C: partition Active before the boot is fixed can cause a problem that cant be reversed It is very frustrating to keep asking the same questions over and over and not recieve answers to them...... that is why I put them in RED.
I feel like you want me to "just mark C: Active and not ask any questions"
I really do appreciate your help and patience.

You'r making it difficult. Windows installation disk has a boot repair.

Under Disk Manger, make C: drive Active. Yes, you can have more than one disk active (MBR = set)
Disconnect all other drives from the MB (Disk 1 & 2).
Boot from the Win 7 installation disk and do a boot repair.
Once you can boot from the C: drive, on BIOS change the boot priority to disk 0, reconnect Disk 1 & 2 drives to the MB.
Under Disk Manger, make P: drive not Active.

Sorry, I missed that. Thank you Mega... I will mark it Active and see it that solves my problems. It may be a day or two I am having to deal with a sick dog. I have made backups of C:\ but still dont know if they will be usable after fixing the boot.
Again thanks for your help and I will let you know how it goes.

Don't worry, you won't loose anything as long you do what I told you on #3, in same sequence.
