My hard drive recently crashed on my gateway laptop. I have the microsoft windows xp media center edition disks. When i put the first one in it says press any button to boot from cd. i press a button and it starts to load. Once finished it comes to a screen that says Windows XP Professional Setup at the top of the screen. And then it says to set up windows xp now press enter. i do so and i press f8 at the license agreement to continue. The it comes to the partitions list on the list it says Unknown Disk (there is no disk in this drive.) It tells me to use the up down arrow keys to select an item on the list, but if i hit any of the buttons it tells me to, ENTER to set up windows, C to create partition, and D to delete partition it goes to another screen that says there was a problem detected and windows has been shut down. How do i install this on my laptop?
