Disk 2 Does Not Boot OS When Selected as the Boot Device on Startup

How did you make the "copy"?
A screen shot from Disk Management would be useful.

Also, your reason for wanting to do this in the first place would help with suggestions.

I used EASEUS Partition Master to copy the partition.

I can't do exactly what you are describing interms of removing sata cables etc...
I have a laptop Disk 0 is inside the laptop, Disk 1 is in my ultra bay (so I can't use the CD ROM).

Should I physically remove Disk 0, take Disk 1 out of the ultra bay and put into my laptop (which now makes it Disk 0)? At this point I could use the CD ROM in the ultra bay.

I am wondering if another option would be to:
1) copy the hidden (1st) partition on Disk 1 to Disk 0
2) Do a drive copy (image) from Disk 0 to Disk 1
After this I would loose my 2nd partition on Disk 1, but at this point it is the same as the 1st partition on Disk 0. I just don't know if after I do all this that the problem will be fixed (i.e. I will be able to boot into both Disks using F12).

The reason for your problem is that you must image or clone and not copy an OS to have it's MBR intact.

You were correct to then add it using EasyBCD from the System OS on Disk0. This gives you access to it. There is no more you need to do unless you want to write the System Boot files to Disk1 as they are on Disk0, which would then allow you to boot either via the BIOS using the Boot order or one-time BIOS Boot menu key.

To do this without the ability to unplug Disk 0 during startup repair, you would disable disk0 in BIOS while the Repairs are being run until Win7 on Disk1 starts on its own. It is already marked Active so you needn't do that - as must be done first for Startup Repair to write the System boot files when run up to 3 separate times with reboots.

Once Disk1 Win7 is also a System Active self-booting HD, set the preferred one to boot first in BIOS setup, then use the one-time BIOS boot menu key to boot the other. This keeps them separate to come and go as you please, whereas using a Windows Boot Menu interlocks them requiring surgery to remove one. You would then remove that menu using EasyBCD>Edit OS entries>Delete.

Or leave it the way you have it now, booting off Disk0 into the Windows Dual Boot menu. You have the steps here how to make Disk1 independent if need be.

Hence my question earlier on - what do function do you want to achieve?
Is it a safety backup OS disk if the main one goes bad?

If you "clone" a drive and have the 2 attached at the same you will have 2 drives with the same disk signature. Now I believe the Windows OS resolution is to force one offline.

Two Product Keys need.

Yes, what.
