Joost,

I installed refind to the esp partition of my disk according to what I
have understood so far from https://wiki.gentoo.org/wiki/Refind and the
meanwhile up again site https://www.rodsbooks.com/refind/installing.html

The disk is a nvme disk put into an nvme-to-usb adapter, so I can easily move it between my existing (mbr) machine and the new uefi-machine.

The efi partition looks like this now:

.
=84=80=80 EFI
     =86=80=80 BOOT
     =81   =86=80=80 BOOT.CSV
     =81   =86=80=80 bootx64.efi
     =81   =86=80=80 icons
     =81   =81
     =81   =86=80=80 refind.conf
     =81   =86=80=80 refind.conf-sample
     =81   =86=80=80 refind.log
     =81   =86=80=80 refind.log-old
     =81   =84=80=80 vars
     =81       =84=80=80 = PreviousBoot

I left out the numerous contents of icons.
refind is installed to teh default BOOT/bootx64.efi as I have no access to nvram up to now.

The disk looks like this:( gdisk /dev/sda)
Number  Start (sector)    End (sector)  Size =       Code  Name
    1         &= nbsp;  2048          4526= 07   220.0 MiB   EF00  PEFI
    2          = 452608       461826047   220.0 GiB&= nbsp;  8300  PSYS



My EFI/BOOT/refind.conf has this entry:

menuentry Linux {
     icon EFI/refind/icons/os_linux.png
     volume PSYS
     loader vmlinuz-6.1.9
     options "root=3DLABEL=3DPSYS ro rootfstype=3D= ext4 mds=3Dfull"
}

And /etc/fstab :(the essential parts only)

LABEL=3DPSYS  /         &= nbsp; ext4   defaults,noatime,nodiscard     1=        1
LABEL=3DPEFI  /boot/efi   vfat   umask=3D00755&nbs= p;            &= nbsp;      0       0=
efivarfs /sys/firmware/efi/efivars efivarfs nosuid,nodev,noexec,noatime
0 0

When I am trying to boot this (uefi-machine) I get

/dev/root can't open block device

or

please append correct root=3Dboot option.


The kernel is compiled with all necessary drivers built in not using
modules. I don't like initrd or intramfs.

I decided to use the partition label PSYS because I cannot see
(like in legacy bios) to which device my disk got connected.
So I relay on refind which can pass partition labels to the "root=3D&q= uot;
option of the kernel as I have read.

Do you or anyone reading this thread know what mistake I have made
in this configuration of refind.
