Re: windiws cannot access the disk
Try using the program Killdisk. This will permanently erase everything that has ever been written to the HD. Whenever I run into this problem, I run this on the HD and Presto, setup now recognizes the drive.
However, if this is a SATA drive, sometimes certain drivers must be loaded first. These drivers can be found at the manufacturer website. Once downloaded, you will have to use a floppy disk to load them (or usb flash drive if it is set up as bootable device). To load the drivers once downloaded and stored on bootable device, you will have to run winxp setup and press F6 when prompted at the bottom of the screen to load third party raid or scsi drivers. When you press F6, nothing different will happen. Setup files will continue to copy and setup will again try to look for your hard drive. When it does not find it, you will be prompted to look for drivers on your bootable device (the floppy/usb drive you loaded the drivers on).
Just note, after using killdisk, data recovery will not be possile for the partition you erased by using killdisk. What this means: Everytime your format a HD using Fdisk or windows setup, nothing is technicaly erased until that particular spot on the HD is written over, that is how data recovery businesses restore lost or erased data. Once you run killdisk, it re-writes over all data making it completely invisible to partition recovery programs. If you are not worried about any data on the disk, then this should be no concern for you, just some info.
If this does not help, I will be happy to walk you through the manual HD setup in winxp setup procedure, it is quite easy once you find what you need.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Which version of xp are you trying to install 32 or 64 bit ?
Your ability to install a second operating system on your Windows 7 system hinges on one thing: partitions. If your computer has only one partition, you can't dual-boot your system without erasing all information on your computer. Two hard drives, or two partitions, enables you to dual boot. Check this information first, before proceeding.
Click "Start" and type "disk management" into the search bar. Click on "Create and format hard disk partitions" in the list of programs to open "Disk Management." Look at the list of partitions and available drives. The information here will be different on every computer. "C" is your primary hard drive and active operating system partition, and this drive contains your Windows 7 installation. You can't install Windows XP here without formatting the system. Check for secondary drives and partitions in Disk Management. Your system may have a "D" or "E" drive. Some computer manufacturers create a hidden partition with recovery software: don't remove this partition. If you have a secondary partition called "D" with more than 2GB of free space, you can install Windows XP here. b> Installing XP b> Insert the Windows XP Setup disc into your CD or DVD drive and close any windows that appear. Shut down your computer with the disc in the drive. Turn the computer on and look for a message saying "press any key to book from CD." Press any key on your keyboard when this message appears. Most computers are configured to look to the CD or DVD drive first, before booting to the operating system. If your system doesn't recognize the disc, you will have to enter your BIOS and change the boot order. Look to your manual for information on changing the boot order. Press "Enter" on the "Welcome to Setup" screen to load the Windows XP setup program. Read the license agreement and press "F8" to accept. Windows will detect that an operating system is already installed on your primary partition and present a list of other partitions to install XP. Use the arrow keys to select your secondary partition ("D") and press "Enter" to confirm that you want to install XP here. Then choose what to do with the partition: leave the file system intact or format the partition using FAT32 or NTFS. Windows XP supports both file systems, but requires NTFS on partitions larger than 32GB. You don't need to format the drive to install XP. Follow the prompts on screen to enter your personal information, serial number, and date and time. The setup program copies files to your PC and reboots -- don't press a key to boot to the CD. When you have to operating systems installed, a DOS screen appears asking you to choose an OS; press the down arrow key to highlight Windows XP and press enter to complete the setup. You will have to choose this every time to boot into XP, otherwise your computer will boot to Windows 7 by default. Hope this helps.

If you want both OS you need to do a partition on the HD to proceed.IThat what i can figure from your quest.But if you just want XP just do a clean installation of it.
Perform a clean install of Windows XPA clean installation consists of removing all data from your hard disk by repartitioning and reformatting your hard disk and reinstalling the operating system and programs to an empty (clean) hard disk. For more information about important things to consider before you partition and format you hard disk and how to partition and format your hard disk by using the Windows XP Setup program, click the following article number to view the article in the Microsoft Knowledge Base:313348 (http://support.microsoft.com/kb/313348/ ) How to partition and format a hard disk by using Windows XP Setup programTo perform a clean installation of Windows XP, follow these steps:
Back up all important information before you perform a clean installation of Windows XP. Save the backup to an external location, such as a CD or external hard disk.
Start your computer from the Windows XP CD. To do this, insert the Windows XP CD into your CD drive or DVD drive, and then restart your computer.
Note To boot from your Windows XP CD, the BIOS settings on your computer must be configured to do this.

Follow the instructions on the screen to complete the Windows XP Setup.
If you have successfully installed Windows XP, you are finished. If these steps did not help you install Windows XP, go to the "Next Steps" section.
If you have a valid Win XP Pro CD and want to install the operating system you'll need to format your hard disk drive. If you have allot of data on you're hard disk drive, (In Win 2000) Suggest you create a second partition within the free space of you're hdd and install windows XP Pro. Boot you're system with the XP CD. Pay close attention to the display screens. Follow the instructions for creating a second partition.
Format the new partition. (Quick). Install windows XP on the new partition. Once completed you can copy your personal data to win XP.
If you choose to keep the win 2000 partition and you do not wish to have a dual boot system than remove/delete the root files from the 2000 partition. These files; Autoexec.bat and Boot.ini. You're new XP Boot.ini should read like this;
[boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
Once you're satisfied an no longer need win 2000 use windows diskmgmt.msc from the run command to delete the win 2000 partition.
Win 2000 uses a FAT16 where Win XP uses the FAT NTFS.
compaq cq40 is one particular model from compaq which is literally designed for vista and when you want to install win xp ;it doesn't work becoz the BIOS block it;the only way out is to downgrade the system BIOS which is a risky thing.check your bios model and version and google for a lower version and download it and flash the ealier BIOS.gooogle more on How to downgrade BIOS
Set CD rom drive to first bootInsert your CD
folow the on screen instructions
be patient, it may take up to an hour,
and then two houers to install drivers,
-> if you want me to find the drivers for you, plz state your computer name and model.
I know this problem,
The HDD is a SATA disk, win XP setup cannot identify a SATA controller on it's own
you need to load the driver (from a disk) so you may need to download it first.
I think this is the correct link
extract the files and burn to a CD or Floppy then run win XP setup by booting from CD
you should see in the begining of win XP setup from CD it prompt you to press (I think) F2 to add RAID or SCSI Controllers, (this prompt is at the bottom of the screen)
Then follow the propmts to load from the disk you made earlier. you should be able to select the controller from a list. (short list)
you should then be able to continue and hopefully Win XP setup should now be able to see your HDD and give you choices about which partition (as per normal)
you want to remove all partitions before installing winXP (you can then make whatever partitions you wish)
Hope this helps
