Best undelete program after MBR to GPT conversion?

January 5, 2020 at 01:59:14
Specs: Windows 10
Hello everyone

I installed W10 and stupidly chose the wrong disk for MBR to GPT. I did it during installation via diskpart - clean - convert gpt.


I already tried Remo Recover and EaseUS Data Recovery. Both did an OK job, but both left A LOT of "lost" files. Files that lost folder structure or got renamed. Is there any other program you recommend I try?


It's a one terabyte disk, single partition, almost completely full.


Thanks in advance!

"It's a one terabyte disk, single partition, almost completely full."
Once you have all your important stuff backed up, best you do an clean install..

Insert your W10 install disk & make sure it boots from it. Make sure no other drives are connected.
During the install, Delete all the partitions, keep hitting Delete until Delete & Format are greyed out
You then have an unallocated drive.
Proceed with the install.

I installed Windows on a different one, nothing was written on this disk. Like I said, I chose the wrong disk, the "correct" one was used for installation and this one is unattached untouched.

Trying to get my head around what you are trying to do.
Is it a laptop or PC?
Are you trying to put W10 from one drive to another?

"Trying to get my head around what you are trying to do."

Do a recovery on a disk that had a MBR to GPT conversion done to it, without nothing written on it after that. Forget everything else :)

"Are you trying to put W10 from one drive to another?"

No, it's a PC with two disks in it. Two physically different disks, not two partitions. During installation I chose DISK1, realized my mistake, went back (before installing or writing anything on it) and installed Windows on DISK0. Now I want to recover data from DISK1 before I format it, since it's currently just unallocated space invisible to OS.

Got it.

I think this tool will do it.

Uncable DISK0 whilst trying.

Use Lazesoft Recovery Suite Edition. Open up & go to Disk Tools > Lost Partition Recovery.

So I don't mess up again? :D

UPDATE: Lazesoft Recovery proved to be vastly inferior to previously mentioned two programs.
I guess it's time to count my losses and move on.

Try Recuva, while not always perfect, it might find some missed by the others. It runs within Windows, I used it a few years ago and it was pretty good on 'normal' files (pics, word, excel, etc.), not as good on less common file types (at least then).

By the way, I ALWAYS recommend unplugging ALL other drives other than the one you are installing your operating system on. Even if you do not make a mistake choosing the wrong drive (common enough), Windows often puts parts on both disks and sometimes the system will no longer work if you unplug, remove, or replace the non-system drive until you do a repair install of start up repair. This is a known issue with Windows installers and MS should warn you about it or fix it. It goes back to Windows 95 at least.

Final update: in one last desperate google atempt I stumbled on an old forum post about "Getdataback". Gave it a shot and it did the best job yet!

Scanning was twice as fast and it found most files.

Recovered over 95% of the files. I'm calling it done.
