  1. Install the SSD to the computer correctly via the SATA cable.
  2. Close the computer case and restart the computer.

Method 2:Change the Boot Order in BIOS

When the SSD is configured as the primary BOOT option, it reflects the clone drive won’t boot. To make the SSD Bootable as BootDisk, you can change the boot order in BIOS.

  1. Continuously press a specific key (usually F2, F8, F12, Del) to enter BIOS Setup.
  2. Use the arrow keys to select the Boot tab. Here, you can select UEFI/BIOS Boot Mode as Legacy or UEFI.BIOS settings
  3. Once the adjustment has been made, press F10 and restart your computer.

Generally, an active partition should be a primary partition. The boot files of the Windows operating system are located in a primary partition. So, if the system partition is not set as an active partition, Windows won’t boot after cloning to SSD. You’ll have to boot from the old hard drive, then insert the SSD in the hard drive enclosure and connect the case to the PC.
