2tb internal drive unallocated

On my desktop PC, I ran a windows update. After the update, the machine would not boot up stating "no operating system"

After trying everything I could, I bought an internal 250gb SSD, put it in the machine, loaded Windows 7 pro 64 bit back on the PC.
I plug in the original 2tb Seagate Baracuda drive and it shows in bios and is listed in disk management as unallocated. There is no drive letter on the drive and it is not listed in MY Computer.

I need the data on this drive.

After reading many thread here (most from 2014) I have looked at and downloaded different software to attempt to fix the drive.

Partition Guru (eassos) listed what seemed to be all the files from the disk. However, in the scan they all lose their names and this would be a tragedy for me.

It seems from what I am reading, that the partition/partitions were deleted?

Mini Tool Partition Wiz stopped working at 85%

At a bit of a loss and throwing myself at the mercy of the experts.

Hi Gsearch,

Welcome to Seven Forums. Windows update causing the PC unbootable is not heard of - atleast till now.. It may just be a coincidence driven by other factors.

Now do not do anything till I return. Most OPs try to do this or that and only make the HDD worse.Just relax.

And tell me which version of MiniTool Partition Wizard you had downloaded.

Will be back after another hour.

MiniTool ver 10.2.1

I am running Partition GURU test as we speak (sorry, already started it) Just a test though, here are the results thus far. and Thank you very much.

OK Let it complete. When complete post the results. In any case, I may not continue with Partition Guru and I shall go my own way :).
Please uninstall PW 10.2.1. Many of the features in it are no longer free. Download and install PW v9.1 from here http://www.filehorse.com/download-pa.../old-versions/



OK, apart from 100MB MSR partition, how many partitions did you have ? Can you list alongwith the volume capacity?

How much data in GB do you have in all?

Do you have another External drive with sufficient capacity to copy all that data if it can be recovered?( I am always pessimistic as far as data recovery is concerned - nature of the job :))

Partition Guru finished its search:

OK, I had seen that SIW2 had in the past always recommending Partition Guru. He is more conversant in using Partition Guru. So I would request SIW2 to assist you and continue with Partition Guru.

I do not know what partitions were on the drive prior to fail.
I do have an external with the capacity to hold any data from the trouble drive.

I have downloaded and installed 9.1

SIW2, I do not know if it looks correct in layout. I am not sure what partitions were there. I am sure that the Dell partition is correct, it is on most Dell PCs

My Dell laptop has 4. Oem, Recovery, OS, and hibernation
