How to create a bootable windows usb from iso using FreeBSD?

[cracauer@]

In my case simple dd for iso works and the flash drive now able to boot, but installer unable to see my disks (SATA) and asks for drivers.

That is precisely what I experienced and warned about some posts back. The downloadable *.iso doesn't work (for me). I had to download and run the iso maker program that MS provides.

I do this all the time.
The Win10 ISO is a bootable image.
It is entirely reliable.

If RUFUS is available for FBSD it does a great job of creating EITHER an MBR or UEFI boot image on the USB stick.

Caveat: this is all within the Win32 environment, so I have no experience doing the same in FBSD.

If this fails on your FBSD machine then boot the Hirens Boot CD which is a Win11 PE environment then run RUFUS from this.
