I used to use Microsoft Disk Cleanup YEARS ago and it works no problem on a HDD Windows 7. Now I just ran Disk Cleanup (with default settings - which is to clear temp folder, clear recovery/rescue files, update files, etc. etc).... on my SSD C:\Windows 7 - I do still have the old Windows 7 on the D:\ HDD (which was cloned to C:\ using the Samsung 840EVO SSD clone tool CD. After reboot - Windows fails to start. It forever keeps on System Repair - reboot - System Repair - reboot - forever. It says lots of files are corrupted. I tried to do a recovery - but it says my recovery files have been deleted. I tried installing Windows 7 ontop of my existing Windows installation (Upgrade option) but it won't let me - saying Windows was previously installed via Windows itself... Someone please help! PS: I can't clone my HDD again since it's been so so so long. I just want to recover my SSD drive.
