    Thanks for your advice, tried everything... sadly it seems to be the actual physical hard-drive, but it is still under warranty so am returning it today. Thanks again.

Its NOT the hard drive itself. Its the master boot record on the hard drive that has failed. The master boot record is like an index or an address book of a hard drive. It hold records of whats on the hard disk and the physical location of files and directory's. What most likely happened was the computer was NOT shut down correctly and a power serge corrupted the master boot record or someone accidentally or purposely deleted files they should not have. If you are not able to follow jmorgan123 advice, the easiest way to fix this is to re-install windows using the recovery disk (operating system cd), HOWEVER you WILL loose all your files on your hard drive as you will need to reformat your drive during the re-install. If you are unsure how to install windows put the system recovery disc in the drive and follow the on screen prompts. If you still can get your computer working after you try a re-install of windows, maby your best bet is to return the computer under the warranty.

Your computer is not recognizing the hard drive. Hopefully your have your operating system cd. Put the CD in the drive. Boot from the Windows CD. It has three options: Recovery Console, Repair Installation, and Normal Installation. Try the Recovery Console. It should scan your hard drive and detect Windows installations, and ask you which one you want to examine. It may ask for your administrator password. Then it should give you a C: prompt. Get a directory (dir) and if it looks okay (no garbled text) and reports the free space, things are probably okay. If you get to this point with no trouble: At the C prompt, say FIXMBR . I'm not sure what kind of output it gives, but it should rewrite your master boot record. Then at the next C prompt, say FIXBOOT then enter. That'll rewrite your partition boot record. The two boot records are the first steps to booting the operating system. Now, try booting without the CD. If it boots, then the FIXMBR and FIXBOOT worked. But I suspect you'll have the same error.

    If that works and you continue getting the same error, boot from the CD again. Press 'Enter to Setup Windows now' or some such. Then, you want to perform a Repair Installation.

    Don't worry, this won't remove or delete any of your files or settings. It only replaces Windows OS files.

Operating system not found

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

My sony notebook PCG V 505 AX stopped booting with message "operating system not found". I took the help of the 3 system recovery CDs which came along the machine.While the first CD runs...

The problem seems to be in your cds. In this case, especially if the product is still in warranty, you can ask from Sony website if they will send you a new set of cds.

Whenever I switch on my laptop, I have a message on the screen saying: ''Operating system not found'' and I can't do anything else... The laptop is not responding anymore.

This error message could be caused by the laptop not detecting the hard drive.
Check the BIOS to see if it detects the hard disk
If not the hard disk may be faulty or needs reseating. If the hard disk is faulty it needs to be replaced and Windows installed on the new hard disk.
A virus program may have infected the computer and removed or changed some system files - in this case Windows needs to be repaired OR Windows re-installed - this is the best option.

No operating system found

If the error message says "No operating system found" it is most likely a faulty disk controller or a faulty hard disk.
Reseat the hard disk, if this doesn't work you need to test the hard disk another way. Remove the hard disk and connect it to an USB hard disk adapter and connect it to a working computer's USB port. If this computer sees this as an external hard drive and you can open the folders and files then the hard disk is OK and the fault is the disk controller on the the 4115c laptop.
If the hard disk is not detected then the hard disk is faulty. You need to install a new hard disk, install Windows and the laptop's device drivers and programs to get a working laptop again.

When i turn on my e system 4213 laptop. keeps coming up with error message operating system not found. please help

Hi make sure you have no usb pen drives, floppy disks, or cdroms inserted then switch on the machine. If you still get the same error then your hard disk drive has malfunctioned or corrupted. If you have a restore cd or DVD insert this and restart the machine you may get an error message stating your hard disk drive is not found if it has malfunctioned.

Operating system not found

When your laptop starts up enter the BIOS setup and insure that the drive is recognized. If not re-seat the drive and try again. Also, are you sure the drive is compatible with the laptop.

Operating system not found

I probably meant to say "reseat" the memory. Just remove the memory module(s) and reinsert them in their slots. This problem can also sometimes be resolved by reseating the hard drive. I had this happen to me just the other night. The laptop slid off of my lap and fell to the floor. Just fell about a foot and a half, and didn't hit all that hard. Kinda partially caught it as it went. But the laptop didn't like it and I had a message of "Operating system not found". Reseating the hard drive had me up and running in about 30 seconds.
