Can no longer opt boot to Windows; Parallels and Boot Camp issues

Question

So I was reinstalling my Parallels since it wasn't reading my Boot Camp partition correctly and I removed my old boot camp profile in Parallels. I figured this would only affect Parallels. After all, I was going to make a new one since my Parallels wasn't working very well. The removal of the profile seemed painless and it was instantaneous (so I don't think it formatted the partition). I then went to restart, and now my comp won't boot to the partition.
I can no longer view (or access) my files from Windows. I panicked and restored the profile from the trash, but I still can't access the partition. I can't even see Windows from the Start Up disk, but Parallels can detect that I have Windows 7 (even though it won't boot properly).What do I need to do to be able to get my Windows partition back? Do you have any idea whats going on with my comp? Can the removal of a virtual machine profile delete an entire OS in an instant?
Disk Utility says that my partition needs to be repaired, but I don't want to do anything until I get an expert opinion.

Please tell me what I need to do! Thank you!

Answer 1

This is a table I use to verify that Testdisk is correct.
GPT 3 Start
GPT 3 Size
GPT 3 End
NTFS Start
Sector Offset
NTFS Size
NTFS End
584882296
1269536
586151832
586151936
104
390621177
976773113
Leave your Testdisk display and start a new Terminal Window. Please use the following steps. The 104 sector positive offset is a good sign.
You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
Rebuild GPT4 using start/end offsets
Sudo gdisk /dev/rdisk0
P  (print the full list of parts)
D  (delete)
4  (part 4)
N  (new part)
4   (part 4)
586151936 - Start offset in bytes  (start point for Bootcamp part)
+ 390621177 - (Size offset as opposed to End offset)
0700     (Windows part type)
P           (print list of all parts just to see what changes will be made)
W         (Write the new GPT)
Y           (Yes! really write the new GPT)
  This will delete and re-write the GPT partition info for /dev/disk0s4. 
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 6. Accept all other defaults that Gdisk offers.
Sudo gdisk /dev/disk0
P  (Print list of parts)
R   (Recover)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 boot flag)
N (part 3 boot flag)
Y  (part 4 boot flag make NTFS bootable partition)
W  (Write the new MBR)
Y    (Yes! write the new MBR)
Reboot
Here is an example of the Q&A in the second set of commands.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #2 (MBR partition #2)
Enter an MBR hex code (default AF): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #3)
Enter an MBR hex code (default AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #4)
Enter an MBR hex code (default 07): 07
Set the bootable flag? (Y/N): Y
Test 1 - Does Bootcamp Volume show up in Finder?
Test 2 - Can you see files in Bootcamp Volume?
Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.
