Operating system not found

You will probably have to re-install windows your laptop might have come with an install disc, insert that into your cd drive and restart your laptop, windows should walk you through the installation process.

Sadly the disk is corrupt, buy a new hard drive and get the data off the old one.

Your hard drive may be faulty, this is why the Windows operating system not found.
Go into the BIOS and see if the hard drive is detected, if not reseat the hard drive and boot up again.
If the Windows operating system not found then most likely the hard drive is faulty and to get the Notebook working again, replace the hard drive, install Windows on the new hard drive plus the Compaq Presario 1692 device drivers and your programs.

You can download the device drivers from the Compaq/HP WEBsupport/download page. Make sure
you select your model laptop and the Windowsdrivers you require and install them. Click on this link to download thedrivers: -

try setting boot from cd in bios if your trying to install

HI There,

Unless someone has gone into what is called your BIOS and disabled your hard drive as a recognizable device, your message most likely means that the WIndows System on it is corrupted enough (maybe virus) that the "boot sector" of that system can't be seen by the computer and it could also mean that your hard drive is ruined.

This isn't a problem you can just find a quick fix for. My first concern, if I were you, would be important data you needed to retrieve. In that case you would hope that someone can put your hard drive in an external enclosure, and just get the data files off it.

If you have a Recovery Disc of any kind for your Compaq, you could insert it and start from that disk and it might repair and restore the files that are needed to see the Windows system and start the laptop again.

It's very hard to say exactly from a distance with what you've told us.

Best Regards,

TheSelkie

Just copy and paste the above link in your address bar, it will bring you to the file download site. It would be helpful if you have a free 7-zip program or WINRAR or other file extracting program to open the file once download. Or download from compaq site

On my Compaq Presario Windows 7 laptop, I have got "Operating System not found" error, to fix problem,Windows Boot Genius helped me finally!

what operating system are you trying to install.
If windows. You need the disk. Then when you switch on the computer you hold f12 or f8.(should display on the bottom of sreen)this will take you into the bios. you need to change boot order to boot from disk. Then you have to format hard drive etc. this can be quite tricky to explain. From this point i think your best option at the minute is to type what operating system you are installing into youtube. theres tons of people showing you how to install operating systems

your operating system wasn't found because kill disk wipes your hard drive clean.
You have to re-install your operating system, all the drivers, and any programs that you might want in your computer.
Boot into the BIOS (tapping the delete key during initial boot-up should get you there, or follow any instructions on the bottom of your POST screen to get into "set-up") and make sure your DVD/CD drive is the first boot option, then put your operating system disc in the drive, and re-boot...the drive should read your CD, and boot from there.
