Environment Variables Changed After nVidia RAID Mirror Broke

I was doing a fan repair on a running IIS Server when I accidentally pulled the SATA cable off of one of two disks of an nVidia RAID. At first I didn't notice the cable was pulled and continued putting the cover on, and when I returned to the monitor for the server I noticed the web site had gone down.

After plugging the SATA cable back in and while rebooting the server, I noticed that both disks were marked as degraded by the nVidia console. When the server rebooted, everything seemed to be okay, other than the fact the mirror was now broken, but I later noticed that although the server was booting to the C Drive, many of the environment variables had been changed the the new I Drive on the now present "second" drive.

The original mirror had three partitions, C,D & E. Now I have two recognized drives with three partitions each, and the second drive has I,J, & K partitions. If I remove the second drive and try to reboot, I can't get past the logon screen, and every time I login it just reverts back to the "hit ctrl alt del" popup, however, if I boot with both drives I can log in, but can't connect to the domain controller.

All I want to do is get my environment variables back the way they were so I can eliminate the second drive and reinitialize the RAID configuration. Can I do this using the recovery console, or is there a better way?

Below is a list of my environment now, I just want "C" to replace "I". Thanks in advance for any help...

Let it finish doing the rebuild. shut it down, change boot path so that the other disk is primary (as it was before this happened), and then reboot.  It should go back the way it was before.

The drive I accidentally unplugged was the primary master, so when it rebooted, it set the secondary as the master. I didn't pick up on this fact until I changed the boot drive on the RAID BIOS and the OS Software recognized both drives again. The problem I had after that was that it saw each drive as a separate array and it still wouldn't see them as one drive in the hardware configuration. I just put in a new unformatted drive and everything worked again.

So the main problem was my stupidity in not checking which drive was the boot drive, which is basically what dlethe said to change back. I couldn't do the rebuild until AFTER setting the boot drive and inserting an unformatted secondary drive, however.
