cloning M.2 SSD windows 10 does not boot

Thread needs solution

Hello i tried to clone my Windows 10 system disk from a M.2 Sata (Samsung 850 evo) to a M.2 NVMe.

I used Linux boot to do it.

IT propose to create new system partition with GMT

Cloning was ending ok, but after reboot (uefi) Windows doens't boot anymore.

I tried several time with ni success.

do you now how to process ?

Julien, welcome to these User Forums.

Was your M.2 Sata (Samsung 850 evo) drive formatted for GPT or was it MBR?

If it was MBR, then you need to ensure that when you boot the Acronis Rescue Media that you boot this in Legacy/MBR mode to avoid converting the target M.2 NVMe drive to GPT as part of the clone action.

See KB 59877: Acronis True Image 2017: how to distinguish between UEFI and Legacy BIOS boot modes of Acronis Bootable Media

Thx for your answer.

Unfortunately as soon as i install my m.2 nmve disk iam not able to boot as legacy ... but only uefi. I also read that it is not possible to have nmve disk with mbr. After cloning i have 2 partitions . One 100mo gpt and one windith windows 10 system. But windows boot is always ko

Julien, from a quick search on Google it looks like the issue is not just UEFI with NVMe SSD drives but whether the SSD has an OPROM to support booting or not?

See webpage: Has anyone been able to boot from an NVME drive on a non-UEFI motherboard? which has some discussion on this topic.
