New SSD not bootable

[cogi]

I have cloned the original SSD to a larger SSD (using Macrium software) and replaced the original SSD in my desktop. The new SSD is correctly shown in PC Hardware Diagnostics UEFI but BIOS reports no boot disk found and the computer does not boot.

An "expert" told me that this might be related to differences between MBR and GPT. How can I check this and what would be a suitable work-around?

The new SSD is a WD Blue 3D NAND SATA SSD with capacity 250GB. 

The original SSD is a Samsung SATA SSD with capacity 119GB.

Hi:

I recommend that you clean install W10 on your new SSD by making bootable installation media using the Media creation tool from the link below.

Download Windows 10 (microsoft.com)

Since your PC originally came with W8.1 from HP, if you are asked to enter a product key during the installation process, select the 'I don't have a product key' option and W10 will install and automatically activate once you are connected to the internet.

After W10 has completed installing, you can install the drivers and available software from your PC's support page.
