Cloned disk won't boot

[Darren_Hib]

My mum wanted a new computer to upgrade from her old one.

She bought a brand new Beelink SER5 Pro. She wanted it to be set up to look exactly like her old computer, so I cloned her old drive to the new blank NVME drive installed in the new one. When I turn the computer on, I am greeted with this screen (attached)

I went into the bios to change boot settings because her old computer was running as MBR. So I changed the Beeklink to LEGACY mode but it still won’t boot. It says no bootable media found.

What am I doing wrong?

Forgot to mention it’s WINDOWS 10.

Describe the process you did.
What cloning software did you use?
Did you take out the NVMe drive and install it into the old PC to do the transfer?

@Darren Hib - still with us?
