Question SSD in M.2_2 slot will not boot on MSI B550M PRO-VDH WIFI motherboard ?

[bch123]

Hello, this motherboard has a 500 GB M.2 mounted in M2_1, near CPU. I have mounted a Kingston 2 TB in M.2_2 and cloned 500 GB to new 2TB and have kept same partition sizes.
I tried in bios to select 2 TB as boot disk, no succes, then I mounted new 2 TB where the old 500 SSD was, in the M2_1 socket.
But still unable to boot. Then I reinstalled the old SDD in M.2_1 and the 2 TB in M.2_2, and I have access to the SSD in M.2_2 with a fine speed, but no boot ?

I have a display card in socket PCI_E1, I cant figure out what is wrong.

I need some help, please

After cloning for first boot from cloned drive,
original drive (clone source) has to be physically disconnected.
This step is not optional.
If you fail to do this, drive letter assignments get messed up and you have to redo cloning.

After have tried several times, I cloned a 2TB M.2 NVMe SSD and a WD 500 SSD, no luck even when I replaced the source drive with the new ones after cloning.

Then just to try something else I used Lazesoft Windows Recovery and tried One Click Fix Crash Solution, and surprise it fixed both disks.

When you have a standard disk, it normally have a C-drive as boot, but when you clone the new disk you have other drive letters, can Windows automatically change drive letters when you boot a cloned disk for the first time, or is there some kind of bios error ?
