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.
