I have acer A515-54G which has 512 SSD on which genuine windows is installed. I have an another harddisk on which ubuntu is installed. when i restart and plugs the hdd and press f12 it gives me 2 options 1. boot ubuntu 2. windows boot loader.So, to load ubuntu i return while selecting option 1 but the ubuntu doesn't loads. So, can you tell me the procedure, so that i can boot ubuntu properly.
thanks :)
