I need help with my laptop, which is a Compaq Presario. I replaced the hard drive a few months ago, and I installed Windows XP onto it. It worked fine for a while but then, for whatever reason, it began to say "This copy of Windows must be activated before use. Activate now?" When you click, "OK," it said, "Windows has already been activated." When you clicked ok after then, it brings you back the beginning. It was a never-ending repetition... So I decided to just start from scratch on my computer and restore everything. I put in this compaq restore CD that I found in my house and did everything the CD said to do. Towards the end of the CD process (at like 98%) it said "Too many errors found, restore must halt." And then it stopped. My computer restarted itself and it didn't go back to the "Windows must be activated, etc." but rather went to the screen that displays the different start up options. When it went to load normally, or in smart-mode, etc it wasn't able to load. This is expected... I put in the Windows XP CD to attempt to install it onto the computer. After the set up window loaded, and I clicked install, it came up with message, "Setup did not find any hard disk drives installed on your computer." Obviously, seeing as I just installed a new hard drive, there is a hard drive on the computer. Please help me out. I need to get this laptop working by the end of the week. Thank you.
