A iso file is like a zip. Many files and folders on a single file.
You don't boot from a iso file.
- You can burn a DVD using a win 7 iso file. It will boot as Legacy or UEFI.
- To make a Win 7 USB boot able drive:

Open a CMD window as administrator and type:

diskpart
list disk (it will list all drives. Identify the USB drive number)
select disk n (replace n by the USB drive number obtained with list disk)
clean
convert mbr
create part primary
select part 1
format fs=fat32 quick
assign
active
exit (to exit diskpart)

If you have a Win 7 installation iso file
On Win 7 use 7Zip to extract all files and folders from the Win 7 iso file to the USB drive.
On Win 10, mount the iso file and copy all files and folders to the USB drive.

If you have a Win 7 installation DVD
On another computer that has ODD, copy all files and folders from the DVD to the USB drive

To make it UEFI boot able you must add the \efi\boot folder

To make it universal (all Win 7 versions), go to \sources on the USB drive and delete \sources\ei.cfg.

To install as UEFI
Reset BIOS or load defaults.
Set Disk mode to AHCI, not RAID
Select OS mode = CSM or Select OS mode = other + UEFI (depends on BIOS).
Disable fast boot and secure boot

Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
To install as Legacy-MBR you must boot the installation drive as Legacy
To install as UEFI-GPT you must boot the installation drive as UEFI.

If you have a UEFI BIOS, you should install as UEFI-GPT
Detach any other drives (SATA or Power cable) from the MB.

During POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name).
Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.
