I am having the same problem. I have an HP computer, which did not come with a Vista installation disk. It lets you make a series of 'Recovery Disks' (set of 3 DVDs). I have just copied the contents of all 3 of these recovery disks to my HDD, but vLite won't accept either the main folder or any of the subfolders as valid for the installation files. It gives an error "can not find the expected files..." The folder that looks most promising is one called 'preload', which contains several .wim files. There is another directory called sources and another called boot. But I tried all of these, and several other directories, but vLite will not accept any of them as correct for the vista installation files. Does anyone have any insight into specific file names it is looking for? That way I could search for them to find the directory that contains them.
