I did a clean install of Windows 10 on my new SSD for my Lenovo laptop like 4 months ago. And Windows 10 was working fine until I dualboot up my old Windows 8 that was still on my HDD to use a program. Then later when I try boot Win10 up it failed, and I find through cmd that all files and folder like Windows, Program Files, Users, etc. went missing on my Win10 SSD (only log files remained), but I know they are there because there is around 40GB of data used up on the SSD, while only 7GB showing.
At first I used just sfc /scannow on another laptop to fix it, and my files and folder reappeared. When I thought I fixed it and plugged it back to boot it, the same thing happened again, all the important folders disappeared. Again, I ran cmd as admin, but when I tried
sfc /scannow /offbootdir=d:\ /offwindir=d:\windows
It says, Windows Resource Protection could not start the repair service. Ever since then I can't fix it using sfc /scannow.
I also tried checkdisk and defragment tool, but it does nothing significant. Then, I used Recuva to recover data, but no relevant data shows up. However, I do notice the path of the files that Recuva recovered is of the form "D:\?\...".
So, I suspect that when I boot up my Win8 it triggered something in the Bios, and did something (maybe hide partitions?) on my SSD. Or did Win10 locks and hid my files and folders so that no one can access it? Does anyone know how to fix it and how it might have happened?
I desperately need help. Thanks in advance for the help.
