I partitioned my 1TB external HDD into 4 parts. I use one to store files. I booted Kali Linux from my 16gb usb stick and installed kali on one of my external HDD partitions. The installation was successful but I cannot boot my PC from that partition of my external HDD; if i boot from usb, it skips and loads windows from my internal HDD. How do i boot from a that partition of my external HDD where kali is installed.
