Hello Diego, I have find out that when I want to move non raid nvme drive under uefi with EFI partition, I must add this option manually in boot menu, that's only correct way.
Hello, I have 2 identical R6515 systems under UEFI. Same BIOS settings. I have one NVME drive INTEL P4510 (SSDPE2KX010T8) with debian installed (automatic partitioning). Debian OS booting fine automatically. I can see PCIe SSD in slot0 under uefi boot option. When I put this drive to another system it wont boot. When I put it back, it works without problem. I tried everything. I can see in UEFI boot option only PXE NIC device. When I add boot option manually via "Add boot option" select drive and select grubx64.efi file it works properly after restart, but this is not the correct way. It looks like that new system have problem to read EFI partition from nvme drive automatically. Any thoughts?
Moving NVME drive under UEFI to another identical system
