Long story short, I have a win 7 on one drive and installed win 10 on another drive, physically different drive. Whilst in win 10 I tried to access my user profile on the win 7 drive - prompt came saying 'you dont have access to this folder, click ok to get access permanently - accidentally I clicked OK. Initially didnt see a problem whilst in win 10 but on next reboot I wanted to boot in to win 7, I got the black screen of death with mouse.
Reading the net I followed a thread and changed permission on the drive using CACLS & ICACLS, this improved it so that instead of black screen I got the Win 7' default blue screen where the login should take place but no log in and the screen flashes to black every now and then.
Tried to restore registry from win/sys32/config - no cahnge.
Next boot into win 10, the drive with win7 is there but no size is shown next to the drive and it is inaccessible.
Have tried repair - cannot repair, system restore - cannot find any restore point where there are many, Safe mode the same, low res the same nothing works.
I place the win 7 drive in to my linux PC and all the files are there no issues.
I then decided to take a image of the partition before doing anything else to it, used Acronis to get the image and Acronis does not seem to have any issues reading the drive. reading the image, all the files are there.
What I noticed, was two exe files in the root of my win 7 drive, these are: SetACL.exe and subinacl.exe. These files may be legit but I dont see these files on my other win 7 PC or on the win 10, so I am wondering why there are there in the first place and if they are causing the problem.
I have not really lost any data so i am not interested in recovering data but to recover my win 7 drive, so anyone with any ideas? Second attachment is my win/sys32/config - where I tried restoring registry, not sure if all OK there.
Latest update: removed both SetACL.exe & subinacl.exe, no change.
Safe Mode, repair, last good, low res etc. all dont work. I know the drive is fine number of CHKDSK finds nothing wrong. either a corrupted file or a malware which I doubt the as I have AVG & Malwarebyte monitoring in real time and they found nothing. Currently drive is not accessible in Windows Explorer but it is in Command Prompt. See attached.
