Windows 10: Booting from an external nvme ssd

So i have a nvme m2 usb drive that i have Ubuntu on, and have successfully booted into on windows on my main computer.However i need to do it on my laptop and this seems to be a problem. I don't know why but i just cant seem to. I disabled secure boot, i tried it through usbc aswell as a through a dock and my laptop a dell xps won't detect it.One time where i was prompted for the bitlocker password and i thought it was going to work, it booted to windows again. Any help would be very much appreciated

NVME SSD

Tried this, and windows still didn't see the nvme ssd. It was a brand new nvme ssd right out of the box. Nothing works.

 

Migrating Win10 to NVMe SSD

I am going to try what you suggested. I just tried using Linux Mint boot cd to hopefully erase the SSD. Unfortunately there seems to be some sort of encryption on the SATA SSD that prevents Linux from managing the SSD. Funny thing is I never used bitlocker on the SATA SSD.

 

Clone present nvme pcie ssd to replacement nvme pcie ssd?

I have a 500GB M.2 2280 NVMe PCIe SSD (boot drive) that I want to replace with a higher capacity M.2 card.

Where do I put the new SSD during the NVMe to NVMe cloning process? My mobo only has one M.2 slot for NVMe SSD's so do I want to use an external adapter for one of the M.2 cards? If so, do you have a recommendation?

If you have solved this issue for your desktop or laptop I would like your advice on if and what extra hardware you needed during the cloning.

please remember that I am dealing with PCIe NVMe drives ONLY. NO Sata is involved except possibly for a connecting cable from the desktop to an adapter. I am experienced with cloning SATA III drives but cloning NVMe is a little
new to me.
