матрациGoogle searching “The user profile service failed the logon, the user profile cannot be loaded” will give you quite a lot of hits – solutions are relevant to both Vista and Windows 7.
If those solutions did not work for you – I would try those first as they are suggested by people who probably know these things better than I do – then have a look at your C:\Users\Default folder. Make sure you have enabled ability to view all hidden and protected files, and disabled extensions for known file types to see the system files properly.
If there are no ntuser* files in the C:\Users\Default folder, then that’s your problem. When you create a new user account, and you find you can’t log into that new user account (of ANY type), it’s trying to find the default settings to populate your desktop, start menu and the like.
So how did I fix it? Log into your HAA* (Hidden Administrator account) and copy the ntuser files from the working account to C:\Users\Default
It is not a complete solution – as what you have done is provided windows with a default setting that is identical to your working account, including folder pathways to your documents, photos, and so forth. You will need to edit these so that you don’t end up with this same default setting every time you create a new account.
What I have personally done is copied the ntuser files from another Windows 7 computer and that now loads up the default settings and correct pathways to documents, photos, etc corresponding to that user account.
If I find out more, I’ll be sure to update this, as no one else seem to have found a solution to this problem.
