rEFInd finds grubx64.efi but not lubuntu kernel on partition

[Marnick_LEau]

Hi

I'm trying to get refind to boot the lubuntu kernel directly instead of maintaining the manual config and using grub in between. For some reason though, refind only finds the grubx64.efi file (on the ESP), but never the kernel files (on lubuntu's own partition). I have a virtualbox set up with refind and arch installed, where refind does find the arch kernel direcly. Its configuration is the same so I don't know why detecting the kernel doesn't work on the real machine.

Uefi, gpt disks, secure boot off. File permissions are the same, drivers for the filesystems are installed (btrfs).

File details

Arch virtualbox

menuentry Lubuntu {

}

Any help in finding out why lubuntu kernels don't show up directly under refind would be much appreciated :)

Are you sure Arch does not have copies of the kernels in the ESP?

http://www.rodsbooks.com/efi-bootloaders/refind.html
Your kernels must reside in the root directory, in a subdirectory of the EFI directory, or in the boot directory of any partition that rEFInd can read—the ESP and perhaps other partitions.
Perhaps default search in rEFInd is different between Arch & Ubuntu?

Thread asking about gummiboot which was another alternative.

Fairly sure there are no copies in the ESP. There's literally nothing in there besides refind itself.

In virtualbox and on the real machine the discs are both GPT, have the same filesystem under /, same file structure (kernel in /boot). According to what I can read in that chapter, all of it adds up. I tried using the also_scan_dirs volume:/boot (with volume=the label of lubuntu's partition) syntax too but it did nothing.

That thread doesn't reveal much new...

I prefer our forum, but the author of rEFInd - Rod Smith does post in askUbuntu. If you make title something related to rEFInd, he probably will post.

The first word is literally refind?

So use same title in AskUbuntu.
Just wanted to make sure you did not change it to something without rEFInd.

Oooh right this isn't askubuntu...

I'm not into the linux ecosystem much at all, sorry

Major issue was btrfs and several settings in rEFInd.
