Disk Cleanup + SSD = unbootable

[andwan0]

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.

PSS: actually, I think I deleted the Windows folder from the old HDD already - so no way booting up there.

Microsoft Disk Cleanup options:
Downloaded Program Files
Temporary Internet Files
Game Statistics Files
Recycle Bin
Service Pack Backup Files
System error memory dump files
Temporary files
Thumbnails
Per user queued Windows Error Reporting
System queued Windows Error Reporting

---- so how can this corrupted my Windows on SSD?
