Why backup hard drive without booting Windows?

People encounter countless computer issues now and then in their daily life. For instance, hard drive failure, booting problem, creating system image, backup PC to external hard drive, migrate OS to SSD, etc. Some of them are system maintenance operations, while some of them would affect the use of computer. What if you are unlucky to face the problem of booting failure? Reinstall the operating system does help you rebuild the OS, but what about the photos, documents, business contracts, and emails that stored in the old OS? You need to find a way to back them up.

In another situation, say the operating system could start normally. You may also want to backup hard drive without OS since it has faster backing up speed when close all system programs. There are reasons to backup hard disk without booting system. As long as you have one of them, you need to learn how to backup hard drive without Windows.
