Compaq Presario 5000, model 5BW220, made in 2000, WD 320G HD. I'm trying to instal XP Home on a new WD hd. The hd came with a cd. I think it's an installation cd. On the CD it says: "Google Software, Drive Installation, Diagnositics, User Documentation, Google taskbar, Google Desktop, Picasa". On the cd it says: "If Windows is not installed boot from this CD". When I boot from the installation CD it goes through a number of steps then stops at: "Attempting PM ATA Identify-SN......Invalid Response" then the same text except PS is in place of PM with no response. I stopped running the cd at that point because it was taking so long. When I tried installing the XP Home OEM CD before trying the installation CD it went through the partitioning and then through the formatting, but before the formatting was complete I fell asleep. When I awoke the message: "Press any key to boot from CD...A disk read error occurred. Press Ctrl+Alt+Del to restart". Whatever I tried it just went back to the same message even after rebooting. Is the hd faulty or the XP Home installation cd, and is it necessary to use the hd installation cd before installing the o/s? My understanding of computers is rudimentary. Thanks for any replies. xxxxxxxxxx

New harddrives need to be set up to be able to accept an operating system. The CD is the set-up for that. The other add-ons google, picassa and the like is just some free software that you can have to use for later on if you choose to. Now with that said, install the hdd and run the cd and go through the set up program again.Once the set-up has been done remove the cd from the computer and insert the XP installation cd and reboot the system and follow the prompts...This time don't fall asleep....LOL Operating Costs = the cost of operating a business Profits = revenues over and above the operating costs.
