Hi sharathkarthik, Dell has not tested Windows 8 on Inspiron 1545. The available drivers are compatible with Windows 7 and Windows Vista. Hence, Windows 8 drivers are not available. You may try installing the blue tooth driver for Windows 7 in compatibility mode which may or may not work. Please reply for any clarifications.
