I have a Samsung i3 core processor laptop computer and for the last two days i have been trying to install windows 7 ultimate on to it, I have used all the activation tools including daz loader, se7en, hazar, Windows 7 Loader eXtreme Edition 126.96.36.199, Windows 7 OEM Brander & Activator 2.0, under various seperate fresh installations for each nd every one of the loaders. when ever i install a loader nd try to reboot it gives out a blank screen or some times just go freezed. To over come that i used a method to, by utilizing the start up repair> cmd prompt> bootsect.exe/nt60 ALL/force, thus finally booting in to the OS. After doing so when i check into my computer properties it shows that is not activated. The problem is no matter how many times i do that am unable to activate my windows, i have tried three different windows 7 installation disks and they have fetched me nothing but the same problem a raises every time. plssss guys get me some ideas or other methods to activate windows.... thanks in advance.
