A bootable USB media with the ISO file comes in handy if you plan to clean install Windows on your PC. In most cases, it does its job very well; however, sometimes, it may fail to boot your Windows PC or perform a clean install. 

To avoid such unfortunate circumstances, it is recommended to check if your USB is bootable before restarting your PC to initiate the clean install.

  1. Hold down the Shift key and choose Restart from the Power menu. 
  2. On the boot menu that appears, select Use a device option to boot Windows from. check if usb is bootable
  3. From the list of bootable devices, choose the USB Drive plugged into your Windows PC. check if usb is bootable

Now wait and see if your PC successfully boots from a USB device. If the boot is successful, that means the USB device is bootable. 

If the USB drive follows the FAT32 file system and includes an EFI\boot directory, your PC will boot successfully in a UEFI system.

However, booting from a USB drive may fail due to an incompatible file system even if the USB drive is bootable.

Hence, to confirm that the USB is not bootable, you should follow the different USB booting test methods listed below. 

2. Use the Disk Management tool 

  1. Right-click the Windows icon on the taskbar and choose the Disk Management option from the Quick Links menu. check if usb is bootable

  4. Next, switch to the Volumes tab of the USB device properties box. Look for the value of the Partition Style entry. If the USB drive is bootable, boot flag markers such as Master Boot Record (MBR) or GUID Partition Table will be listed next to it. check if usb is bootable
  5. Apart from this, a bootable USB drive may display the Status entry as No Volume/No Media, and Unallocated space and Reserved space will be 0 capacity each.
