Windows 10: How do I boot from my newly cloned NVMe M.2?

I seem to have a very specific problem and I've tried to search everywhere for the right answersI have 1TB SSD for storage like games F:, etc, 1TB HDD for docs, pics, vids, etc E:, and another 1TB SSD C: where I have my Windows installation, and programs Program files etc.I must be on the 3th or 4th day of trying to sort this out now lol, after about 9 attempts of cloning my Windows SSD to a 500GB NVMe M.2 I finally managed to do it, using AOMEI Backupper. After everything copied across which took a few hours I finally had my M.2 with the windows drive cloned onto.I restarted my pc,

Hi Crocodile_aligator

Yes, Windows will load the correct driver for the NVMe M.2. the first time you boot up Windows 10 from that drive after cloning your drive . . .

 

M.2 SATA to NVME clone: Windows 10 won't boot

Problem: Windows partition won't boot after cloning M.2 SATA drive to M.2 NVME. Simply returns to BIOS splash screen are restarts boot sequence.

Background: Cloning process was simple raw dd copy. Drive had EFI, Windows 10, and Linux partitions. Cloning preserved exact partition sequence, sizes, and UUIDs.

Linux partition needed minor tweaks to /etc/fstab due to the device names being different (/dev/nvme0n1px vs. /dev/sdax), but boots fine.

The disk is GPT, and I believe the original Windows 10 was UEFI - the Linux installation definitely was.

Boot sequence brings up Linux 'grub' menu first. Choosing the EFI partition then brings up Windows EFI boot menu. Fresh Windows install (see below) boots fine from here, old install fails.

Attempts at solution: I did a fresh Windows install in a spare partition and it boots fine. Using the new Windows installation, I've edited the BCD entry for my original Win 10 install. I have
the correct BCD device, osdevice, and path.

Questions:

• What else needs to be done to make Windows boot again?
• Are there any config file or registry changes that need to be made to account for the SATA to NVME move?
• How do I see boot error messages for a UEFI boot failure? No errors displayed and no log files that I can find in Windows or EFI partitions...
