Operating system when starting up message displays no aperating system found. what is the problem?

aperently either they used the wrong oil or they did not reset the command module to erase the message for oil change..this needs to be done..

there is problem with your hard disk. your hard disk wire may be loose. try to remove and refix all sata wires of your hard disk. "operating system not found" message may be coming because you may have not installed any os (windows, linux or mac) in your notebook. try to install operating to system to fix this. there may also be proble with your hard disk, your hard disk may be dead. if your notebook is showing message "operating system not found" without any reason then you may have put your notebook in high magnetic field area. due to high magnetic field, sometimes hard disk's are formatted automatically.

Error 09 - Lower PCA Memory Test Errors
Description
Error 09 checks lower PCA memory locations during the power up test sequence. If a fault is
found during the power up test sequence, error 09 will be displayed. This error code is only used
on products utilizing the dual microprocessor system.
Possible Causes
1. This error message almost always indicates a lower PCA problem when it is consistently
displayed. Failures causing this error message to be displayed are rare.
Possible Remedies
1. If the error message is consistently displayed when the unit is powered up, the lower PCA
should be replaced. It is possible to see this error message displayed intermittently due to
external causes. If the units A.C. input significantly dips during the power up test sequence
the test could fail resulting in this message being displayed. Treadmills operating on
non-dedicated A.C. circuits may see this message displayed on an intermittent basis.

Thank you in advance, sincerely. Blessing.

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

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

Every computer needs a BIOS and an Operating System. The key combination to get to the BIOS is displayed on the screen for a couple of seconds at system startup. If you fail to press those keys the computer will try to start any existing OS. If no OS is found then you MUST install one to use your computer.

This generally indicates a hard drive crash/failure, in which the hard drive will need to be replaced. Rare, but occasionally you will get this error from an operating system glitch. Before you run out and buy a new hard drive, try reloading the operating system. If you have any problems during or after the install, then the hard drive is shot.

Do any of the fans operate ? Is there any aperance of the power switching on?
Look in the back of the printer and see if you notice any leds on in the machine.
If there is no presence of any power, the electronics module has most likely failed.

Could be a sign that hard drive is failing or a problem with Windows. Do you hear any strange noises, clicks?

Try re-installing Windows and see if that helps.

Thanks!
