NTFS stop code error; partition data including OS unreadable (W10Pro)

I tried to merge two adjacent NTFS drive partitions (one with my OS and programs and one empty) using Minitool Partition Wizard. I ended up with a BSOD and NTFS stop code error.

I tried EasyRE to fix this automatically. It failed. Then I tried using Windows 10 installation media to make the repair, to no avail.

I went back to EasyRE, which has GParted on it, to see if GParted could check the partition. It sees the partition, and seems to know my OS is there, but can't read any data on it. It returned an error, but I'm unable to save the details of it onto a flash drive, due to the online instructions not matching what I see on my computer. The message GParted gives me, though, is:

Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for ntfs
file system support: ntfs-3g / ntfsprogs.

I don't know what to do with this information, or how to fix my computer.

I didn't take an image but have all of the data on another machine. I'd like to be able to flip a switch and make the partition data visible, rather than format the partition and reinstall Windows and all of my programs.

Any ideas?

Thanks for the advice. My problem has been solved.

TL;DR: I plugging the drive in to my other computer, and ended up using MiniTool Partition Wizard to check and repair the corrupt partition, which made the contents visible but left the drive still without boot capability. Ultimately I used EasyRE to repair the boot capability.

The longer version:

I plugged my corrupt laptop drive into my desktop computer via USB.

I tried findandmount to no avail. Then after looking around I decided to go with EaseUS Data Recovery Wizard. It found my files and let me preview them, along with a bunch of deleted files, whose boxes I painstakingly unchecked (the default is that everything gets recovered unless you uncheck it) so I wouldn't recover a bunch of junk or files whose reappearance might cause a program to go haywire. But after hours of going through the 200,000-plus files that EaseUS found, when I hit the "Recover" button, EaseUS acted as though the drive/partition that it could obviously see was not connected, and failed to recover anything at all.

Then, though I was skeptical, I tried using MiniTool Partition Wizard, which caused the bad partition in the first place, to check the partition and repair errors. That got rid of the cluster accounting errors by deleting a bunch of orphans etc. (or so it said as it was working), and, astonishingly made the partition and contents visible again to my computer.

However, when I put the drive back into my laptop, Windows failed to load, and I got a BSOD.

But, with a visible partition, I thought maybe I could use installation media to repair Windows. Unfortunately that failed, but I was still optimistic. I went back to EasyRE and tried the automatic repair function again.

Which worked!

My computer now boots, the partitions are visible and the size I intended, and everything seems to be working as it had been, including Outlook and all my e-mail accounts, Sync, OneDrive, and Google Drive (which will undoubtedly update to become Backup and Sync momentarily). I was afraid a database would be corrupted or lost, and I'd end up with file duplicates or disappearing files, but everything seems in order.

Good advice — I've learned my lesson!
