Basically, when I got the error "bootmgr is missing" I created a new boot sector. Thus the table no longer pointed to my windows files or applications, and I couldnt load up anything. I then thought that windows had been deleted as the directory C:\windows didnt exist in the recovery console, so I installed a new copy, thinking it would repair the one that should have been there. Obviously the new boot sector table overwrote the old one and I could not find it even with active partition recovery programs.
Sadly, I think, I will have to start again. At least it was only games that was missing and not my life in picture!
Thanks guys!
