Follow these steps to create a bootable USB from Windows. Note this is similar to my post about A Multiboot USB, but mainly for on the fly single OS booting.
1a. Insert a USB drive into the computer.
- Open CMD Prompt as administrator, and type:
list disk #get your USB drive number, usually 1
select disk 1
create part pri
select part pri
format fs=fat32 quick
- Now just copy and paste the system image to the root of the USB drive. It should be bootable now.
