☛ Upgrade hard drive - Replacing hard drive is the most direct way to get larger space and better performance. But if you don’t want to reinstall Windows or lose any important data, it's a good idea to migrate HDD to SSD, SSD to larger SSD, etc. via disk cloning software.

How to boot from the cloned hard disk?

After cloning the hard drive, you can shutdown the computer and replace the source drive as the cloned target drive. Thus the PC will boot from it automatically.

But if you want to keep the old hard drive as a secondary storage, just restart your computer, press the required key to enter BIOS. Make the cloned hard drive as the first boot option, then press F10 to save the settings and exit.

If it boot successfully, you can also wipe the old hard drive to free up more storage space. AOMEI Backupper includes a Disk Wipe feature in Tools tab.
