Windows 7: Technical Boot Question (2 Disks)

Technical Boot Question (2 Disks)

When I go to my BIOS, I see two hard drives: P0 and P2.
Let's call them as Disk1 and Disk2.

Regularly, I am booting from Disk2.
(By the way, one of the disks is dedicated to operating systems, and the other is dedicated to libraries. I don't know which one is which, since they are identical drives, but as I said regularly I am booting from Disk2).

When I have a boot problem such as "Insert correct media device", I am putting the system repair disc, and (after booting the system repair disc from cd/dvd drive) it gives me the error that "this repair disc is not compatible with your version".
But, when I change the first drive from Disk2 to Disk1 in BIOS, it doesn't give that error and shows me the system repair options.

What does this mean?
Why it is happening like that?
Does it mean that if I remove Disk1 physically or disable it, I can never use any system repair disc?
How can I solve this problem?
What are my options if a system repair disc gives me the "not compatible" error?

It sounds like your boot files are on disk 1, P0, and your OS is on disk 2, P2. You need to have a look in disk management to see whats what. If that is true, you won't be able to boot up to your OS if you remove disk 1.

Disk Management shows like this:

disk1

200 MB - GPT Protective
465 GB - NTFS

disk2

200 MB - GPT Protective
200 GB - NTFS - System, Boot, etc. (C)
and goes on

Is there anyway that I can move the boot files from disk1 to disk2 or

-disable disk1
-create new boot files in disk2
-boot with a live cd
-format disk2 boot partition (or somehow erase the boot files in there)

something like this, I don't know, is it possible?

or what happens if I clone disk1 boot partition (200 MB GPT) to disk2 boot partition (200 MB GPT) and then use gptsync to rewrite the mbr?

Any ideas?

Hm, that shows drive 2 as being the boot drive? I'm guessing maybe its the GPT Protective partitions that are messing things up. I have no idea what they are for though? Where did you get those drives from?

Unplug Disk 0 (Drive 1) and see if windows still boots up. If it does that means your boot files are on Disk 1 (Drive 2). If that is true it means your repair media really isn't compatible with your version". I'm guessing it could be that it was made before you installed SP1, or maybe created on a different PC. Where and when did you get the repair disk?
