Problems when using EasyUEFI to move EFI partition to new NVMe drive

[TravisEdwards]

I just upgraded my computer and installed a new NVMe SSD. I want to move the EFI partition from the old drive to the new drive using EasyUEFI to boot directly from NVMe. However, after copying and adjusting the boot entry, the computer still reports No bootable device.

I have tried:

Using Manage EFI System Partition to select the NVMe drive as the primary ESP

Adding a boot entry manually in EasyUEFI

Checking in BIOS, the boot option has appeared

But when booting, it still cannot boot.

Is there any step I am missing? Does EasyUEFI fully support moving EFI between SATA and NVMe drives, or do I need additional steps in BIOS/UEFI?

Are you sure you have set the newly created boot option as the primary boot option? Perhaps you should provide some screenshots to describe your issue in detail.

Since the NVMe drive is already visible in BIOS and the new boot entry appears there, I’d check the EFI boot files themselves before changing anything else.

Make sure the EFI System Partition on the NVMe is FAT32 and contains the correct Windows boot files. If necessary, you can recreate them from Windows Recovery or Command Prompt using bcdboot, then make the Windows Boot Manager entry on the NVMe the first UEFI boot option.

I’d also temporarily disconnect the old SATA drive after confirming you have a backup. That makes it much easier to tell whether the system is genuinely booting from the new NVMe rather than falling back to the old EFI partition.

If you’re also checking drive/interface compatibility while doing the upgrade, this storage section is useful for comparing SATA and NVMe options: [link removed]

The important part is to verify the new NVMe can boot independently before deleting or changing anything on the original drive.
