When you get the message "The operating system cannot be found" it is generally caused by an outdated BIOS card. The best thing to do is contact your computer manufacturer for help. If you don't want to buy a new BIOS card or computer then follow the steps below.
The following steps I will tell you is not guaranteed that it will 100% work for all operating systems nor will it guarantee it will work at all. These steps might damage your computer. By reinstalling your operating system you will be wiping out all of your saved memory so do not follow these steps if you are not willing to take the risk otherwise contact your manufacturer for help!
Lastly, read all of the step and follow them carefully before you actually do them!
Step 1: Have your copy of windows ready to go and any hardware, software, etc... because all of your saved data will be gone. This is important if you don't want to spend hours finding the CDs you want to install.
Step 2: Turn on your computer and immediately press F12.
Step 3: Once you are in the boot menu go down to Boot Sequence.
Step 4: In Boot Sequence disable Hard-disk drive C. By doing this your computer will boot from the copy of windows so have your copy of windows ready.
Step 5: Exit Boot Sequence and go down to OS install modeand enable it.
Step 6: After you enable OS install mode open your CD-ROM drive and put your copy of windows in.
Step 7: Once your copy of windows is in exit the boot menu and save what you have changed. After you saved your boot menu changes restart your computer. This time do not press any buttons and it will take you to a screen that says "Operating system cannot be found." Wait a couple of seconds and you will here a beeping sound and a following message that asks if you want to continue.
Step 8: Select yes and it will take you to a blue screen. At the blue screen you will see a bunch of your systems processes loading. Wait a couple of minutes and it eventually take you to a screen that says reinstall windows.
Step 9: Select reinstall windows and it will take you to a screen with a list of your hard drives. Select hard drive C to reinstall windows (Remember, this will completely wipe all of your data that you have saved on your computer.)
Step10: After you select hard disk C it will take you to a screen to install windows. Select install windows and the process of installing will begin. This will take a while so you might want to find something to do.
Step 11: After an hour or so it will be done and you will have your newly installed windows. You will also need to reinstall your modem before you go surfing the web and you might want to reinstall any hardware, software, or anything else that you are missing.
