check ur bios settings by pressing F2 F8 or ESC as once ur in the boot settings the bios will tell u if ur harddrive is registering if it is change the boot order to boot of usb first had this issue b4 on another k series asus i used 64bit 10 pro changed from home 64bit as home was buggy. As long as ur boot order is right load it from a usb3 port do a bios update if it needs 1 to should boot asus are stuborn to force boot i did i got a couple asus laptops i have converted ni issues if in doubt load up window 8.1pro first & try it that way i got a 8.1 pro boot which i use all the time as my boot then update to 10 from there asus k series are a mongrel unless u read up on forums i can guide u threw if u need to i use primarly asus gear & learnt a few tricks
