This might be simple.
Assuming your son didn't make any internal changes to your computer. The problem may be that he changed your boot sequence to boot to floppy or CD instead of the Hard Drive.
Do the following:
As your computer is starting you will briefly have the option to hit F8 (I think F8 Might be another) for "start up menu or options".
This will take you to a screen of text where following the on screen text areas and moving the curser with the keyboard arrows and enter or escape check your boot sequence (the order of where your computer is to look for start up information)
It should read as follows:
#1 HDD1 (this text may vary)
#2 CDROM drive
#3 FLOPPY (if you have one) or other removable drive
If your son changed this and forgot to it back your computer may be trying to get start up information from a CD or Floppy instead of your hard drive.
Once you've changed this (assuming you needed to change it) following the instructions use the key to "save changes and exit"
Your computer should now boot up correctly.

DVD codecs are missing. You can download a codec pack for free and install. This should solve your prob. Older DVD rom drives did not come with onboard codecs. When you format and reinstall the registered codec can get cleaned away. Like baby out with the bathwater...............
Starting a Recovery
Turn on the computer and immediately begin pressing the F10
key repeatedly until a Recovery Screen appears.
You can also start a recovery from recovery discs, or from Windows. For more information refer to
Performing a Full System Recovery in Windows XP
Back to topRecovery is taking too long
If your computer stops responding after using the recovery program, do the following:
the computer appears to have stopped responding after restarting from a
recovery, please wait, it may take several hours or longer to complete
the initial Windows XP setup process, especially if a recovery was run
from a recovery disc set sent by HP. A Standard recovery may also take
longer, depending on how many files are stored in user accounts (like in
Exit the stalled recovery process by pressing the POWER
button on the PC until the power turns off, this takes approximately five seconds.
recovering, disconnect personal media drives, printers, scanners,
cameras, camera-type memory cards, and other devices that did not
originally come with the PC.
If you are using recovery discs, be aware of the following items:
you created the recovery discs using Recovery CD Creator, be sure to
run the recovery from the same drive that you used to create the
the discs with a soft, clean, lint-free cloth wetted with distilled
water. Wipe from the center of the disc to the outside edge. You may
also use disc cleaning kits or disc restoration kits from your local
computer store. These kits produce better results than using cloth and
You may also use available CD/DVD Drive cleaning kits to clean the laser reading lens of the CD or DVD drive.
Try running a full system recovery again from the hard drive by turning the on the computer and pressing the F10
key until a Recovery Screen appears. This performs the recovery from the hard drive.
Either your Hard drive (hd) crashed or your hd cable or port is faulty. if your software is corrupt boot with a boot disk (assume you are using XP or Vista), press R on the blue options screen. you will be given a black dos prompt screen. Type in fixboot and type Y for an answer.
Can you use that port to read any other device?What operating system are you using?Did it work previously?Windows 98 you will have to install drivers.Chances are that old computer has a usb 1.0 so it might not work.However try another device in that port or any usb port on the computer to see if any ports are working.Does your scan disk work on another computer.Have you done a windows update recently.Make sure you try all the above.
this is not an issue that an adware program will fix. Your Operating system may have been compromised due to a virus infection. Try using windows restore (Within Programs>Accessories>System Tools>System Recovery)
This will recover any changes made to the system runtime.
If that does not work, that was compromised and windows may need to be re-installed.
Disk boot failure is usually a sign that your operating system has become corrupt in some way.
If you've got your Windows disc, put that in the CD rom, then boot the computer.
There's a "repair" option that you can select, instead of re-installed Windows.
That *should* fix the problem.
It's also (thought unlikely) possible that your hard drive has died completely.
Since there is no CD in the drive the computer is attempting to boot of the hard drive and not finding the files it requires (unless you have it set to boot off a USB device before the hard drive).
You cannot simply use the recovery disk from one system on another because these disks install drivers specific to the hardware of the computer for which it is intended.
You need to find the CDs that came with this system or contact HP and order them. Please note that running a recovery CD will wipe all your personal data from the system (this may very well have happened already), since this drive will not boot, connect it to another system as a slave or use a USB enclosure to see if there is anything you can salvage.
