HP Pavilion Power 15-CB060SA Wont boot from new SSD

[bunjatec]

Hi,
I've just cloned my SSD image from an WD green (WDS120G2G0G0B-00EPW0) to a new Crucial P3 500GB PCIe M.2 2280 SSD

While the old drive still boots, I can't get the new one to boot.

The new drive however managed to boot my desktop PC (which was using internal M.2 ports to clone)
I've upgraded the BIOS to the latest version (F.42), and I have tried with and without legacy support enabled.

The laptop model number is HP Pavilion Power 15-CB060SA. Here is a link to the specifications:

I'm running out of things to try, so I'm posting here in the hope that someone has a good idea. 

Are some compatible SSDs not actually compatiable?

Just FYI, I have 3 of these laptops and I've upgraded all of them in various ways, this is the 1st time one has fought back..!!

Thanks in advance.

Machine supports M.2 SATA 3 SSD, its old SSD is a SATA drive. The new M.2 NVMe SSD won't work.

Please use M.2 SATA, not M.2 NVMe

The issue appreas to be with cloning GPT drives, I've sucsessfully done a fresh install on the new NVMe drive, however this now means a manual reinstall of everything, and a manual port of user data 😞 

The old drive was an M2 SATA drive but the HW supports both SATA and PCIe, the new drive is significantly faster..
