Hi, I have looked around the forum but could not any suitable reply to my problem. I have a Dell 15R-5521 laptop that came pre-installed with Win 8 and i was told that activation code for this windows 8 is hard coded on the motherboard or BIOS (I might be wrong about where it is stored). For gaming reasons i downgraded it to Win 7 (Ultimate), i tried using this loader v 1.6.9 by Daz I installed it and that went successfully, as required i restart my laptop. That's where the problem occurs, I just reach the DELL logo and nothing happens after that. I have used this copy of windows 7 with the same loader on my other Toshiba laptop and it has worked smoothly. I have basic idea about setup changes and installation. Can I get some help to solve this issue. Thanks, Rahul
