I have a Samsung N150 laptop. I renamed the full computer name and username (both are the same), required to restart, when I restarted I get an error "incorrect Disk, remove and try again". same error when starting safe mode.
I removed all devices but now when I restart the computer it says Windows has shutdown to prevent damage to the computer.
We'll need more info than that. Please update your question to include more information like the exact error messages you see when your computer boots up – Vinayak – 2014-08-09T07:49:11.590
