Not finding operating system during boot

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key
this will vary depending on your computer and operating system

Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart
if this fails to fix the problem

During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer

you could select the option start at last known configuration that worked this will tell what file has been corrupted or missing you might be able to work your way through problem if you are unable to find a solution

restart back into safe mode you might need to select your operating system to load into safe mode

click start control panel administration tools computer management in the left panel events + to expand then system you will see all errors in right panel right click select properties this will tell you what has occurred and the time it occurred

you might use the system restore to restore your system to an earlier time
click start all programs accessories system tools you should see your system restore option

hope this helps

This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

hi

go to the Bios setup and set the first booting device as CD drive and it will check the CD first

cheers
pls rate if it was any help

Boot sequence isn't enough. You have to turn OFF (disable) the boot from network. The error your seeing is result of the network boot rom not finding PXE server to boot from. Again, be sure to disable boot from network.

you got an OS problem try to re install your OS.

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.
