Hi guys.

I’m trying to install CentOS 9 Stream on a nvme – before I
start tampering with other OSes – would anybody have an idea why… after a seemingly successful installation OS wont boot –
hardware sees nvme drive, bios does – it does not see new/any EFI boot entry?
To make it more bizarre – virtually identical hardware, only CPU is Ryzen Pro 3900 and not 3700 – and same CentOS
succeeded, it boots & starts fine. I’m going to try again with the latest available ISO as of today, but in the meanwhile – I’m hoping you can share some thoughts/ideas.

many thanks, L.

  • that is one thing I did not try. I should have added – where booting 4TB fails, on same hardware other, previously used & smaller NVMes worked &
    still do work, when put back it. I’ll report back tomorrow.

  • NVMe requires EFI booting. In some UEFI implementations, if you say “BIOS +
    UEFI” or however it puts it, CentOS will put a `/biosboot` partition on the disk, not `/boot/efi`, giving exactly the symptom you report.

    Put it into pure UEFI mode, ensure the partitioning step creates
    `/boot/efi`, and I bet your symptom will go away,
