Windows 7: Laptop stuck at hp logo screen

I have a dv4-1225ee laptop. I removed my laptop hard drive and attached it to my pc and installed windows xp. Because in my laptop it asked to press a key, when i press any key it didn't detect. I attached the hard drive to my laptop. But the screen is stuck at the hp logo. If I remove the hard drive and switch on the laptop. I get the insert boot disk and press any key screen. I formatted my hard drive and attached it to the laptop again but same result. Please help me.

On the Notebook make sure you have a good connection with the HD Drive.

For installing Win XP, you need to install on the Notebook & not on a Desktop.

How to make sure it is connected properly. And also i made a little hole in the hard drive connector while removing the hard drive. I will Install windows 7 in pc and attached to laptop and reply.

Will the Hd Drive show in BIOS?

Why?

By mistake.

In the Hd Drive or the HP/Compaq connector?

As I said it doesn't respond at all. So I cant go to bios. I made the hole in the hd connector. Thanks for the quick reply.

Replace the HP/Compaq connector.

How to replace and how much will it cost?

You will need to buy from HP/Compaq, cost unknown.
