Solved Recover unallocated win7 hard drive from Ubuntu

[dorruk]

Hey guys, it was just that the blue screen came up while I was on Windows 7, and afterwards, the computer would not boot Windows, gives a blue screen.
But my Ubuntu as a 2nd operating system installed on the same drive works fine. I opened GParted Partition Editor and I have a 596 GB single "unallocated" partition.

I'm pretty sure the files are still in there because it successfully reads and loads Windows system files in Safe Mode, but does not boot them, blue screen again. And my personal files in Ubuntu are still there.

The Win 7 installation USB doesn't install because the hard drive does not appear. So how do I recover my hard drive into its drive C and drive D partitions? I can risk formatting drive C where Windows 7 is in. But I want to recover drive D at all costs.

The System Recovery Options are accessible (ie windows command prompt), but I do not have a restore point.

Any help would be appreciated. Thanks.

Okay got it solved after 4 hours of work. I used GParted Live, as a bootable USB.
In its terminal window, ran the following:

sudo -s
fdisk -l

to monitor hard drive status. After that I ran:

testdisk

which has its own UI you can move around with up down arrows and Enter button to play around your HDD. After that I ran:

fdisk -l

to monitor hard drive status once again to see if it worked. I recommend GParted bootable version rather than the desktop version when a virus screws up your HDD to its entirety.
