Black Screen,Copy of Windows not genuine + Temp acount after partition

PLEASE TAKE THE TIME TO READ THIS, AS IM GETTING EXTREMELY DESPERATE NOW. I WILL BE FOREVER GRATEFUL.
After partially partitioning my hard drive using Active Partition Recovery programme (was stopped half way through partition), I found that all desktop icons and apps had disappeared. The start menu became unresponsive, and I knew I had seriously messed up the system. I immediately restarted the computer and logged in with the normal account only to come to a Black screen with nothing but a white cursor and the message 'This copy of windows is not genuine' in the bottom right of the screen. (It is genuine though, as I forked out my hard earned ****in* cash to buy it from the local computer shop).
Anyway ive been surfing the web all day for fixes to this problem, and have managed to make small progress, by starting Task manager and creating a 'New task' for 'explorer.exe'. However, this brings up a few Icons and the old desktop but I get the message 'You have been logged on with a temporary profile' and as such - I cannot access any folders and any changes I make will be deleted at next login. I eventually found the option to transfer administrative privellages from 'TrustedInstaller' to 'Andrew' (my account) but I get the error 'Cannot access control editor. The system cannot find the path specified". Ive tried 'chkdsk' command prompt - which took a few hours - to no avail, and when I try to open any applications I get the message 'no such interface supported' .
So Ive obviously corrupted the profile or screwed up the registries when I tried to bloody partition the hard drive, but im not sure what to do now. Im very hesitant to do a complete utility restore because I have so many important work related documents stored on there (as do my parents), family photos, etc. and I know they are still there, as I can see all the folders are still in place (and take up room on the hard drive) but I cannot access any files within them and the system cant seem to locate the file path of certain apps - thus I cannot make backup copies of anything.
For example, iTunes is one of the few applications that comes up on the desktop on this temporary profile, but when I try to open it I get the message 'Apple application support was not found'. Just to add insult to injury however - Paint, calculator and notepad seem to function fine on the temp profile, the only drawback being that they are next to useless applications.
On a sidenote, the 2nd profile that mum uses wont even log in whatsoever, it just logs back out straight away. Also, safe mode is not much different. I can run certain tasks as administrator, but I cannot access any files or control panel. Im not very tech savy so I probably shouldn't of tried that partition shit in the first place (which ironically was to recover files off a damaged external hard drive), but all that means is that I have no clue what to do now.
Should I try inserting the win7 disk that came with it, running a system repair, changing the boot order in BIOS, or deleting the corrupt profile(s) and making a new one - or will that cause all data to be lost? Im still holding onto any hope of recovering the files on the computer, but that hope is dwindling, and I have a major assignment - among other things - that I had written which is in the bowels of this bloody machine (im using a mates computer at the moment).
So basically I don't have a clue in hell what to do next? If any of you have encountered similar problems or can suggest a solution thanks in advance, and A SINCERE THANKS FROM THE BOTTOM OF MY HEART FOR TAKING THE TIME TO READ THIS THROUGH. Needless to say, if I do manage to get my data back -- ill sure as hell be making backups of everything.

Well the account I normally use was the admin account. The second account doesn't work at all, as I said. Except it doesn't appear to function as the admin account anymore when I log into it its a bloody temporary profile, and I cant seem to change that.

Alright cheers il give that a try tomorrow when I go home, but il have to try that in safe mode I guess, or else it wont let me run anything - including command prompt (as it wont let me be the administrator). Another thing, will that delete the files on my old profile? Or should I still be able to access them?

no, what he is showing you is how to activate the built in Admin account, it's a bit stronger than normal admin account, so as long as you dont delete your old account, your stuff will not be deleted

alright, and once im logged in as that built in admin account, how do I go about restoring my old account? or do I just copy everything of value to an external hard drive and then wipe the hard drive clean? also - will I need to do this everytime I log in?

i wouldnt get ahead of yourself, i think he mainly wants to do this to see if this account is acting up also, we dont yet want to delete the old accounts, rather than to see if there's a way around fixing it, plus the admin account has full privelages, so you should be able to run applications (hopefully). But yes, as of now, i would back up everything of importance just in case, if i were you, it would have been done already, considering you have access to an external

dont worry, vistaking will take care of you
