Operating system not found showing on my screen

you need a windows disk and reinstall your operating system

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.

Hard drive failed, replace it

Hard drive maby dead, or formated...

hi goodner,

getting the error "operating system not found" means that the hard drive where the Operating System is installed (i.e. Windows XP, Windows Vista, Windows 7), Cannot be found by you BIOS upon the boot sequence.

When you turn the PC/Laptop, you normal see a screen that flashes flashes with screen that displays the ff:

Primary Master:
Primary Slave:
Secondary Master:
Secondary Slave:

The Primary master should have a value right next to it. If not, either the hard drive is faulty and needs replacement, cable is loose,

If you have a value to it and stil gets the same error the operating is corrupted and needs to be re-installed.

It seems that either the OS is corrupt on your system or the Hard Disk Drive is not getting detected.

To confirm if the hard disk drive is detected you need to go into the BIOS and check if it shows the Drive present.

Just check if the Drive is present in BIOS. If you find the Drive in BIOS You can try to re-install the Operating system using the OS disk.

For any clarification or assistance feel to revert

Hello,

I recommend going into your BIOS and making sure your system is detecting the hard drive(s). If not, recheck your cable connection at the drive and the board. If it is detecting the drive, make sure it is set to be one of the boot drives(I would make it 2nd to the CD-ROM) and reboot your server. If you get the same error, you will need to reinstall the os.
Good Luck

Hello,

its showing operating system not found, because the system cannot detect your hard disk.

Open your system, remove and fix back the hard disk, then try again.

Take care.
