When you start a computer without an OS it will show a message, something similar to this: “no bootable device, insert disk and press any key”.
If the computer happens to not have a ROM chip, it will do nothing, even if you have a cd to boot from.
It will turn on, but there will not be anything for the computer to do.
Can a computer work without an operating system?
You can, but your computer would stop working because Windows is the operating system, the software that makes it tick and provides a platform for programs, like your web browser, to run on. Without an operating system your laptop is just a box of bits that do not know how to communicate with one another, or you.
How do you fix a computer that says no operating system found?
Fix #2: Change or reset the BIOS configuration
- Restart the computer.
- Press the necessary key to open BIOS menu.
- If the screen shows multiple keys, find the key to open “BIOS”, “setup” or “BIOS menu”
- Check the BIOS’ main screen to see whether it detects the hard drive, and the boot order to see if it is set correctly.
Is operating system necessary for computer?
