When i start my laptop, after the logo of window start up, blue screen will appear and auto restart my laptop then again it reboot and then "Reboot and Select proper Boot device" appear. Im currently using Asus A53S window 7. I try google and found out that by changing the boot priorities might help but i failed. At the boot priorities of the bios there sometimes appear to be 2 priorities but after restart and i check my bios again it become 1 priorities. Does anyone know how to fix this? Plz reply ASAP Thx
