G'day Judge-Mental, and Welcome to BC
I am probably not the best person to help you with this, however I am sure others with more expertise in this area will chime in later..
Do you have a backup on an external drive ?

fed up with Windows antics...??....LINUX IS THE ANSWER....I USE LINUX MINT 18.3 EXCLUSIVELY.

If Windows flags the file system as dirty it will do a repair using chkdsk. Unfortunately if the file system is severely corrupted chkdsk can make things worse as you have found out.
I would pull the drive and attach it to another computer using an enclosure or USB adapter. See this page on trying to recover chk files.

You are very fortunate the OS was on a separate partition. After the backup hopefully the disk diagnostic checks out okay. Good Luck
After the OS install and once you get your programs installed I would recommend you create a disk image using Macrium Reflect or Aoemi Backupper, both are free. They will let you create a bootable CD or USB flash drive that can be used to restore a disk image to a clean drive or to a drive where Windows no longer boots because of a corrupted file system as was your case or because of malware.
Macrium and Aoemi can let you recover the whole disk or just one partition of the disk from the disk image. Both let you mount the image as a virtual disk that lets you explore the image on the external drive and lets you retrieve any file in the image. Macrium's method of mounting an image is easier as it can be done by simply double clicking the image in File Explorer and selecting a drive letter as the virtual drive. Aoemi requires you to mount the image through the program itself.
Recovering a complete disk image of about 30GB can be done in minutes instead of hours doing a complete reinstall, reloading of programs, and updating the OS. Of course if your data is in the TBs then the image will take longer. As you already know, it best to have important data backed up to two locations and if the data is highly important one of the backups should be offsite.

I just want to second JohnC_21's excellent advice to do backups regularly to an external hard drive. Situations like yours can occur at any time, and you can have days of frustratingly hard work and/or expense if you don't have these. I've been using Easeus Todo Backup Free for the last 5 years for backup, and it's worked very well for me. It's free for home use. Most folks here on BC seem to like the Macurim program but there are a lot of good free backup/restore programs out there, just be sure to avoid the one included in Windows. It's buggy and unreliable.
Make regular full system backups or you'll be sorry sooner or later.

Whew, finally back in business so to speak. As expected, there didn't seem to be an easy undo, and even the System Restore was broken so I just reinstalled Win7 and went from there. Doesn't look like I lost any crucial data, knock on wood, which is nice.
Anyhow, definitely going to look into these backup programs now, thanks all for the advice!

Thanks for the update. Glad you still have your data intact.
