one week ago i purchased HP-1000 series laptop which came with pre installed windows 7 but my hard drive failed and a new hard drive is given to me but i dont have the cd of windows 7 or the backup please suggest how to install a valid copy of windows 7 using product key
Seems odd that HP would ship you a drive with no OS on it, especially if the laptop was under warranty. Your laptop should have contained a HP utiltity to create an install disk or a repair disk. These would have been your OS install CD's.
Being that it's OEM, I'm not sure if downloading the ISO from microsoft will work, but you can try it.
