Fixed MBR of the drive, it's now seen as unallocated

Hello,

Too much stuff happened so I'm going to list them in the most condensed way possible

1. Installed new OS. Win x64 Ultimate
2. Everything is fine, loading drivers.
3. Drivers loaded, everything is fine.
4. Restarted computer, one drive disappeared.
5. It's now showing up as 2TB unallocated drive in Computer Manager but it's in fact 1TB. WTF!
6. Took out the drive, put it on a external usb-sata drive bay so that I can access it as a USB drive
7. It worked. No problems with the drive whatsoever. Smart is OK. Files are OK. Chkdsk showed no problems
8. I've an application called Active File Recovery. Looked at the drive with AFR. MBR shows problems.
9. I selected fix MBR from the list.
10. Drive is gone. It's showing up as unallocated.

I know that the files aren't gone. Is there any way to fix it without using file recovery software? Recovering an entire 1TB harddisk would take too long and plus I don't have 1TB extra space lying around to copy the files.

it is easier to help you post a screen shot of Disk Management.
See this link if your not sure how to How to access Disk Management in Windows XP, Vista, 7 or 8 to manage hard drives

Disk Management - Post a Screen Capture Image

I'm not seeing your screen shot. There is an icon (place holder) shown but no picture. Maybe it's just me. Is anyone seeing the screen shot?

Something wrong with SomeImage. Uploaded the ss to another site.

I can see the photo. I can't help you beyond that though.

We are missing some crucial information here. As an internal drive, it looked like a 2TB drive. After you put it into the USB enclosure, how did it look like?

If it worked and all your files were OK a) how did you determine that? b)Why did you run Chkdsk and a file recovery program if everything was OK??

Note: It is a cardinal rule that while installing the OS, you should unplug all other internal drives and connect those again only after installing the OS. Had you done that you would not have gotten into this problem at all and gotten this sermon from me

You are booted into Disk1 that does not contain the boot files for Win7, which are one DIsk0.

To correct this to make Win7 boot on its own, Mark C Partition Active unplug all other drives to run Startup Repair - Run 3 Separate Times.

You can also use Bootmgr - Move to C with EasyBCD - Windows 7 Forums.

Once Win7 boots on its own and C holds the System Active flags, deactivate System Reserved using Partition - Mark as Inactive - Windows 7 Forums. You can then delete it in Disk Mgmt.

As to the drive which you ruined by running unnecessary repairs without asking first, I would try a full scan with Partition Wizard Partition Recovery Wizard - Video Help
which is a simple undelete operation. Jumanji is expert on this and can help you determine if it's recoverable based on pictures of the results.
