    Check and make sure the battery seated correctly. Also make sure you did not jar your memory loose. This will prevent . The computer from booting also.

    Check the battery is in the correct way, and check the BIOS settings, as they are most likely gone back to 'default' settings.
    Check that the boot order has your main 'C' drive first or DVD drive then 'C' drive, if that's where you have Windows installed.

    Agreed, but don't forget to set the time in BIOS too, otherwise windows might get pretty f:ed up.
