Its easier than I thought. We require at least 4gb empty flash drive.
first run cmd-> disk part
list disk
select disk Z
clean
create partition primary
format fs=fat32 quick
active
exit
Z is our empty flash drive
Now copy files from root folder from boot dvd of windows to flash root folder and boot from created flash drive.
For windows 2016 its required ntfs instead of fat32, actually if the stick is already formatted then just set it to active:
list disk
select disk Z
select partition 1
active
exit
Z is our flash drive
