I am working on a Compaq Persario 5002us. I just installed a new harddrive. It is an 80 gig from a 40 gig western digital. I can install the xp operating system, but after the install, it keeps rebooting and cannot find it on the harddrive. The harddrive says that there is a operating system on it but it wont get past the compaq logo screen , then it is in a continues loop of reboots and will not let me finish xp install after it loads the drivers. It keeps going back to the install screen of the xp cd and trying to reload windows xp. I can never get to the nice screen of it telling you how many minutes are left. What am I missing? Booting sequence is set up as followed, cdrom,floppy,hd. The hd is on a seperate ide cable. Can xp load on this computer. It was running Windows Me.
