I have downloaded WIN I0...x64.iso to my computer,from microsoft,and burned it on a blank Sony DVD using LG DVD writer tool.But when I set the boot order to DVD drive in BIOS,it does not boot from that DVD and enters the windows loading screen.How can I do that?Please help..I cant even update current windows version as my system files are probably corrupted.Even system restore/reset of windows 10 fails.
