Vaio vgn-nw21sf operating system not found

[MonicaAnd]

Major problem. The computer froze and when I restarted it I got a black screen with the message "operating system not found". Have no recovery disc. The computer is only six months old. What can I do and what happened?

I had Windows 7 on the computer. Don´t care about the files, there is a backup on them, but I don´t have any backup on the op system.

Hi MonicaAnd,

welcome to Questions & Answers..

Most  Vaio's has a hidden HDD recovery partition so you should be able to recover your Vaio back to the  original installed OS and programs just as it was when you first used  your Vaio.

To   do this Start your Vaio and when you see the Vaio logo screen press  F10  repeatedly this should start the recovery utility and allow you  restore the Sony supplied OS and applications..
