Have you first set and saved a supervisor password? Then have you re-entered the BIOS menu with the supervisor password? Then followed JordanB's directions immediately above your post?  Jack E/NJ

I did everything except windows installation as my window is preinstalled.
My harddisk partitions are not showing while installing ubuntu 18. Only bootable USB is showing as /dev/sda. I have Acer Extensa 215-52

Do I need to change anything in BIOS or other settings?
