The problem is why it stucks in BIOS and cannot go to windows after I tried installing Windows 10 last time. That time the screen showed "there is not complete drivers inside". After that when I shut down forcefully and turn it on back the screen appeared in blue color and saying please call technician.
These happened after I send my laptop to a Computer shop for reformat. Then backed home I downloaded the new Windows 10 OS and after completed the laptop cannot be used. I think maybe the shop that I send my laptop do not put all the drivers. and the result my laptop cannot be upgraded and now cannot use anymore. many files located inside and I cannot take them back. so sad. please help me.
