I'm trying to make bootable usb from win10 iso (should be legal, I got in PC magazine). The iso is OK, it works boots in virtual box.
I tried fedora "media writer", ubuntu "disks" and good old "dd"
sudo dd bs=4M if=/tmp/win10.iso of=/dev/sda conv=fdatasync
and while that thing says it's bootable:
/dev/sda: ISO 9660 CD-ROM filesystem data 'CHIPSPEC_WIN10_II' (bootable)
it cannot be booted on none of mine computers, all linux based(meaning I cannot use any windows app to write image or do any investigation there). I did not use windows for years and did not install them even longer. Does newest windows require something special from bios? Is uefi mandatory? Is secureboot mandatory? Or what can be the issue?
