If the cloned SSD is not set to be the first boot option in BIOS, your computer won't boot from it. Therefore, you need to access BIOS and change the boot order to set SSD as the boot disk. Here are the steps:

Step 1. Restart the PC. When the startup screen appears, constantly press F2/F12/DEL to enter BIOS.

Method 3. Set System Partition as an Active Partition

The system partition should be set as the active partition. If the system partition is not set as an active partition, Windows 10 can't boot from cloned SSD. You can set the system partition as an active partition with an easy-to-use partition manager in the WinPE environment. Here is how to do it:

#1. Create a bootable disk and boot PC from it

Reboot PC > Press F2/F8/Del to enter BIOS > Set PC to boot from EaseUS bootable Disk > Reboot PC.

#2. Set SSD system drive as active

Step 1. Run EaseUS partition manager software. On the disk map, right-click the traget partition and choose "Advanced".

Step 2. Then, select "Set Active" from the drop-down menu. The software will automatically execute the operation and create an active partition for you.

#3. Set PC to boot from cloned SSD

Reboot PC > Press F2/F8/Del to enter BIOS > Set PC to boot from the cloned SSD > Reboot PC

After this, your computer should be able to boot up from the cloned SSD and you can make use of all cloned files on the new disk again.

If you've followed through the above three methods, the SSD is still not booting, your SSD may have a problematic clone of your old hard drive. 
The best way out is to re-do the clone. And we'll show you the process in the next Method.
