Re: Operation System Not Found

Ha! Too true!

So considering the error message, could it be a problem with the Windows 7 installation? Is there a way of checking that?

Thanks!

NJCurmudgeon,

 

Hardware checks, then it's an installation problem.

 

Easiest method is...

Restoring Your Computer´s Software to the Factory Settings

 

Manual method is...

Re: Operation System Not Found

Before you do anything rash do you have an external hard disk hooked up when this happens?

Re: Operation System Not Found

We did an experiment. When there is no external hard drive hooked up, the laptop starts normally, both after being shut down completely and woken up from sleep mode. When the external drive is plugged in, the error message appears. So that does indeed seem to be a clue. I haven't heard the fan running excessively after rebooting, but I also know from reviews that the fan can be particularly loud on that model under normal running.

Thanks!

Jim C, Thanks, I forgot about an attached device.

 

Restart the computer and press F2 at the Dell Screen. Look for boot sequence. Make it...

 

CD/DVD Rom

HDD Hard Drive

USB Removable devices

Network

 

Save changes and exit.

 

When you start the computer with the hard drive attached, it should boot for cd/dvd first then hard drive. It will no longer look for the usb attached devices.
