What are the reasons to clone hard drive from bootable USB?

Cloning a hard drive is a favorable choice when you want to upgrade to SSD or make a backup in case your PC goes wrong or can't boot normally. Disk cloning will save you time and energy from reinstalling OS, applications, games, programs, or transferring personal files, which is quite convenient.

However, Windows doesn't provide you much flexibility, although you can clone hard drive via Command Prompt, it remains on the file/folder level rather than the partition/disk level. Besides, what if when your computer can't start normally? How can you copy disks with Windows built-in feature? In such a case, you may need to clone hard drive from bootable USB. The latter content aims to help you complete the clone with a bootable USB flash drive effortlessly.
