You say it's missing, but then you say "Folder is not invisible". I'm not sure what not invisible means.
If you use Windows Explorer, (Start > All Programs > Accessories > Windows Explorer), and navigate by clicking the + signs through My Computer, C drive, Documents and Settings, can you see the folders there?
If so, then you need to Take Ownership. Microsoft guides you through how to do this;
yesterday i lost my documents and setting folder. I don't deleted it. Simply when i logged into my pc i got a error:
Folder C:\Documents and Settings\<ACCOUNT> is not accessible. Access is denied.
Folder is not invisible or something else.
I try chckdsk, Malicious Software Removal Tool, Nod, create new account...
But when I start windows in safe mode everything is ok, folder is there and i can create new account, but in normal mode there is still error.
Thank you very much! and sorry for my English )
