    Windows wont start after 8.1 update wont boot in safe mode

    Last night I updated windows 8.1 from windows 8.
    It got to the stage where it needs to restart so it done that started the configarations and once it reached 100% it restarted.

    Since then what happens is when i press power on the samsung logo comes on the screen then the black screen with the windows picture then the bsod comes up for around half a second and it restarts. then it constantly does this.

    The whole cycle only takes a few seconds.

    Ive tried booting in safe mode but this isnt working so I downloaded kav rescue on another computer and saved it on a flash drive, But it wont boot off this either.

    Any ideas?

    What does the BSOD state? Most times it is a driver issue with the Display drivers. Other times it is hardware.

    The system doesn't have a special key to get into the bios other than the F keys? Sometimes getting those to work takes a special way of tapping them when the system just starts the reboot.

    Have you tried booting from a Powered Down condition? Have you tried without the battery? How old is the battery?
