I’ve been working my way deeper and deeper into UEFI based Windows 8 installation and operation over the past few weeks. This weekend, I stumbled across a fab and free little utility called ISO to USB that can read any ISO formatted file and “burn” it to a USB-based target device of one’s choosing. For me, that usually tends to be a USB flash device (known as a UFD in Microsoft-speak). To act as a repository for any of the Windows 8 ISOs, it must be at least 4 GB in size or larger. For this blog, I grabbed my older and somewhat beat-up but still speedy and capable Corsair Survivor 8GB USB 2.0 model to do the job. Here’s a screen cap of the utility window, upon successfully building a bootable Windows 8 installer from the 64-bit Windows 8 Pro .ISO file (the trick is to format the UFD as FAT32, because that’s the only format that works for a UEFI install):
Sure, it’s easy to use diskpart to do the necessary set-up and drive formatting to get ready to copy the contents of a mounted ISO file in Windows 7 or Windows 8 to build a UEFI install UFD manually. But this free tool does the whole job in one step, as long as you can point to the ISO file you need and have a spare UFD ready to turn into your UEFI bootable installer. Given that using this tool is dead simple and pretty fast, why not take advantage of its capabilities? The price is right, too!
