The "fix" once moved my entire windows folder into some kind of lost and found bin. It was years ago so I don't remember the details. I had to move the files back by recovery command prompt. At least IT gave me the bitlocker key. That whole process sucked
It didn't move anything. The filesystem got corrupted and that directory was erroneously marked as unused space, which is probably why you were running chkdsk in the first place. Lost and found is the correct place to put files recovered this way because chkdsk doesn't know where they're supposed to go. Fsck does the same thing and in fact lost+found is a default directory on most (all?) unices
