Any reason you bury the iniitrd in the options list rather that having it on a separate line?

(My ASUS motherboard for some reason never lets me write EFI variables from within Linux so I have to do it from within systemd-boot.) You can specify the options in the kernel configuration as well: CONFIG_CMDLINE="root=/dev/nvme0n1p4 initrd=/intel-uc.img net.ifnames=0 raid=noautodetect" To add the /intel-uc.img to this configuration you either have to include that in kernel configuration or you can use Dracut to build an EFI image. Kernel config: CONFIG_INITRAMFS_SOURCE="/boot/intel_uc.img" Or with Dracut: dracut --force --uefi --uefi-stub '/usr/lib/systemd/boot/efi/linuxx64.efi.stub' ... Dracut will automatically pick up your kernel installed to /boot (from kernel `make install`) and /boot/intel-uc.img (and other similar things). It will also automatically place the file into In both cases, you have to remember to update the EFI image/rebuild and reinstall the kernel whenever you update intel-microcode. The benefit to this is you don't have to maintain entries files, and you keep configuration generally in one place: the kernel config. Then you just drop in EFI binaries into the correct place and they will appear in the menu. You could have always keep two Linux EFI binaries in ${ESP}/EFI/Linux/ in case the newest one fails.

I'm still running 5.4 but I tried removing the slashes from the kernel and initrds and it booted fine.

It was so simple, and the clue was in an earlier message. # cat /boot/loader/entries/30-gentoo-5.7.1.conf title Gentoo Linux 5.7.1initrd=/intel-uc.img linux /vmlinuz-5.7.1-gentoo options root=/dev/nvme0n1p4 initrd=/intel-uc.img net.ifnames=0 raid=noautodetect All I had to do was to remove the slash from initrd=/intel-uc.img. I did that in all the .../entries files and 5.4.38 also still boots happily. Thanks to those who offered help. -- Regards, Peter.
