I’ll describe the process of creating a bootable USB flash drive with Windows using UltraISO:
1) Start UltraISO, select the required ISO image of the operating system by clicking the menu “File”> “Open”.
2) We connect the USB flash drive to the computer, in UltraISO we open the menu “Bootable”> “Write Disk Image …”.
There where “Disk Drive” we will select a USB flash drive and press the “Write” button below to start the process of copying files from the ISO image.
Before starting the copying, all data from the USB flash drive will be erased.
At the end of the process, the USB flash drive will be ready.
