Oh my what next now? After reinstalling IE7 to get rid of my problem about not being able to access internet options not even from the control panel, I ran CCCleaner. Never used that program before, and so I did something wrong... Windows didn't even start loading, after the POST I got written "NTLDR is missing, press Ctrl-Alt-Del to reboot". Obviously rebooting gave me the same message. So I put in my XP CD and ran a windows repair. The problem was solved and everything was fine... until I came to installing windows updates. I had no problem downloading them, but when I tried to install I kept getting this: It won't let me install anything even if I do it 'custom' one by one. I managed to install only one update - "Microsoft Windows Installer 3.1" And there are 84 updates which I've downloaded and can't install.
