How to use UltraISO?
Download and install UltraISO (64 bit) — you can use the program right after launching it. To do this, open a file, go to the main menu, select “Bootable,” then “Write Disk Image.” In the Disk Drive field, specify the path to the device (flash drive) where the information will be written.
Once you click the “Write” button, all files previously stored on the USB device will be deleted, and the new data will begin writing to the disk. After a short wait, all the information will be completely written to your media.
