The Windows edition listed in BIOS (Vista) is referring to the operating system that came with the computer. BIOS's System Diagnostics will always say the OS is Vista, because that is the original OS that HP put on the system. BIOS itself, however, cannot detect an operating system on the new Hard Drive because there is no operating system. In order to get an operating system, you have a couple options:

Depending on the terms and length of your warranty, you may be able to get HP to reinstall the operating system back onto the new Hard Drive. The amount you would pay depends on the warranty. Many warranties, however, become void when you change physical components in the computer (especially with laptops). If this is the case, you will have to try the next option.
You can buy a retail copy of Windows either online or from an electronics store. The price will depend on what edition you purchase, but it will probably cost you at least $100 US.
You can install a Linux operating system on your Hard Drive. If you've never heard of Linux, it is an operating system based on much of the same code as Mac operating systems, but has a more "Windows-like" feel to it. Linux operating systems are NOT the same as windows, and some programs that work in Windows will not work in Linux; you would need to find the Linux counterpart for these programs. One of the best things about Linux operating systems are that they are absolutely free to download, install and use. A very popular and stable Linux operating system is Ubuntu, which can be found at: http://www.ubuntu.com/

what operating system are you using the error code implies that the driver for the software is not compatiable with your os

Do your Wireless Device (PCI or USB unit) comes with an installation CD? If so, use the CD to install the software/drivers.(Instead of using the Windows wizard). Remove any previous installation before reinstalling with the CD.

Resit your device to a different USB port or PCI slot. If the drivers/software are properly installed, windows will detect and installed the device correctly.

Cause of the Code 28 Error (In general)
A Code 28 error is caused by a missing driver for that particular piece of hardware. There are several of reasons that a driver might not be installed for a device but your troubleshooting of the problem will be the same no matter the root cause.

Resolution
1.Restart your computer if you haven't done so already.

There is always the slim chance that the Code 28 error you're seeing in Device Manager was caused by a fluke with Device Manager or in your BIOS. If that's the case, a reboot might fix the Code 28.

2.Did you install a device or make a change in Device Manager just before you noticed the Code 28? If so, it's very possible that the change you made caused the Code 28 error.

Undo the change, restart your PC, and then check again for the Code 28 error.

Depending on the changes you made, some solutions might include:
•Remove or reconfigure the newly installed device.
•Roll back the driver to the version prior to your update.
•Use System Restore to undo recent Device Manager changes.

3.Update the drivers for the device. Installing the latest manufacturer supplied drivers for a device with the Code 28 error is the most likely solution to the problem.

Important: Make sure you install the drivers for the correct operating system. Example, if you're using Windows 7 32-bit, install the drivers designed for that specific version of Windows. Most Code 28 errors are caused by updating or install the wrong drivers for a device.

4.Update your OS to latest Windows service pack. Microsoft regularly releases service packs and other patches for their operating systems, one of which may contain a fix for the cause of the Code 28 error.

**Note: Certain service packs for Windows Vista and Windows 2000 have contained specific fixes for some instances of the Code 28 error in Device Manager.

5.Replace the hardware. As a last resort, you may need to replace the hardware that has the Code 28 error.

It's also possible that the device is not compatible with this version of Windows. You can check the Windows HCL to be sure.

Note: If you still think there is still a software/operating system component to this Code 28 error, you could try a repair install of Windows. If that doesn't work, try a clean install of Windows. Not recommend doing either of those more drastic options before you try replacing the hardware, but you may have to if you're out of other options.

Hope it helps.

You need to reinstall a fresh copy of Windows XP.
Back up all your data before re installation.
