Why do you need a bootable USB drive

As many users have experienced, Windows system sometimes is prone to be corrupted and then crash and stop working due to various reasons. As a result, the PC fails to boot and the hard drive data becomes inaccessible. This problem usually makes users who are urgent to work with their PC or view their important data crazy!  

What if you have a Windows bootable USB drive? Congratulations! Just go to BIOS, change the boot sequence, and then you can start your PC properly from the removable disk. 

There are the things you need to pay attention to:

  • Use an external hard drive to create a bootable USB drive. The USB flash drive and pen drive are not able to help.
  • Only the first partition of the USB flash drive or pen drive can be recognized by the Windows, while the second and subsequent partition drive letters cannot be allocated.
  • Almost 99% of the Windows systems must have two partitions, the system partition, and the boot partition. If you clone Windows 10/8/7 to a USB flash drive or a pen drive, only the first partition can be accessed. In this case, it cannot boot at all. So you must use an external hard drive!!
  • Besides, the USB hard drive must have enough free space which is bigger than the system drive space!
