Bridge adapter broke in vbox
 

At first i was using vbox in win 10 and my brigde adapter is working f9 till i dual booted my system with fedora 25 .After dualing booting i installed vbox in fedora25 and imported my kali linux virtual machine in fedora .
At first vm is working f9 in brigde mode but after rebooting my system bridge adapter brokes, it works f9 in NAT adaptercan someone tell what causing this behaviour after dual booting .please help me!!!!!!!! ;-;

kali has the network DISABLED BY DEFAULT as a security measure

i tried installing other vm also like win7 and fedora25 both don't work with bridge adapter . i think after dual booting my system it broke up my bridge adapter all vm works f9 with NAT adapter .
