[Help] Deleted Partition Recovery on Windows 7

Hi All

A few days ago i created a new partition on my external hdd that I was going to install OSX (Hackintosh) onto. OSX installed correctly but it kept giving me boot0:error so i thought it might of been the fact that the 20gb partition was a logical mbr. So i changed it and it still gave me the same problem

After that i tried formatting the partition with disk utility and it gave me a error (which i neglected to write down) which resulted in all partitions on the disk being corrupted/deleted. This is what is shown when i connect the disk to Acronis Disk Director

Disk 2 (MBR)
'Local Volume' | 910.5GB | | Primary MBR | Not Formatted | Healthy
Unallocated | 931.5GB |

I tried running Acronis Recovery Expert and it was able to detect that i had 2 deleted partitions but the thing is it took 5 hours just to be able to continue to the next step, during this time the indicator light on the hdd never stops blinking. But when i click on next the RecoveryExpert program crashes.

I have tried EaseUS and Minitool Partition Recovery but when i try and open the program with the hdd plugged in, the program stays at the loading screen and it never opens while the indicator light keeps blinking. I also tried running the hdd through testdisk on Ubuntu but the program idles at the disk selection screen after i select proceed and the indicator light also keeps blinking

The external harddrive is a WD Elements 1TB and i only got it a month ago. Please help i have so much important data on there and im about to cry because ive tried everything

Thanks

 

i already tried running testdisk on windows and on ubuntu but as it said above each time i select the process button the screen just stays at the disk selection screen and the indicator light keeps flashing

do you really think it will be different on hirens bootcd?

 

Full Intellectual Scan - Turned up a useless partition that wouldnt mount (Incorrect space)
Normal Scan - Turned up nothing
Full Scan - Turned up nothing

The only program that seems to recognise that i have a deleted partition is the acronis recovery expert. all other programs stop responding when i open them with the external hdd plugged in while the led indicator light keeps blinking.

Omfg am i utterly screwed? Is all of the data permanently lost?

 

Easus gets stuck at the splash screen when I have my external hard drive connected....

 

Doesn't work as it the program freezes. Is the data on the 910gb partition permanently lost?

 

so i tried what you guys said and it sort of worked. it was able to detect that i had two partitions within the unallocated space that were in good condition. I decided to fix the boot sector for both these partitions and run the create/fix partitioning button in the menu where i selected MBR and then in the logs at the bottom of the window it says that it "Successfully fixed MBR". Currently the program registers the primary and copy boot sector as being valid and i can view all my files that was on it before

But the problem is when i now click the Recover button it still says that

Not Ready for Recovery
Reason: The logical structure of MBR is damaged and contains invalid partition records
Action: You can try to use eith low level tools (like disk editor) to fix records manually, or delete invalid partitions or execute FixMBR command

Do you guys know how i could fix this problem?

i only got the HDD a month ago and i safely eject it every time i use it so i doubt that theres anything wrong with the HDD

 

what do you guys think are the chances of me successfully recovering all existing data or the whole partition from my external hdd
