WIN8 crashes on NORMAL boot. Works fine in Safe Mode. HELP?

I have a Toshiba C660-1QF and I got Windows 7 installed (GENUINE). Bought it like 2 or 3 years back. It was working fine and then I decided to upgrade to Windows 8 Pro. Well, I got the pirated version off The Pirate Bay. It is Build 9200. Got an activator and executed it. NO NEGATIVE ANSWERS PLEASE. IF YOU CAN HELP, ANSWER. I closed the activator as it took too much time. MY BAD. I also tried Windows Update. It said that I had to restart and sign in to update. I restarted and it asked me to enter my password wich I did. It gives the WELCOME screen with the loading sign and then BOOM. The screen goes BLACK. From here cursor is movable. And the ONLY other thing I can do is press Ctrl+Alt+Del and click on Open Task Manager. It ALMOST opens but closes by itself.

Another thing I want to tell you is I have Windows 7 Ultimate installed (GENUINE) as Dual-Boot. ALL my important files are in WIN8. I can open it in safe mode though. I already tried googling it and the only solution I got was to Uninstall My Graphics Driver (Intel HD Graphics).which I already tried but did NOT work.

When I installed WIN8 I didnt do a clean install but just upgraded it, if that helps. PLS HELP.

I know thats a LAME email ID, created it when I was a Hulk fan maybe like 10 years back. I am 15 now. And I am NOT a complete newbie and I KNOW I shouldnt have updated the pirated WIN8. So a medium level complexity solution is preferred. And the MOST important subject is that I CANNOT afford to lose those important files I have. If you have a doubt whether WIN8 is compatible, I assure you it is because I had it installed a few months back but I eventually deleted it. PLS HELP. NO NEGATIVE ANSWERS PLS.
