EFI EXIT type chainloading failed

Eruthon · Aug 13, 2021, 8:35 AM

Your guidance has been very helpful and spot on. It works exactly as I wanted: the grubx64.efi is now shown in rEFInd menu after “Booting…”

But if I understand correctly, wouldn’t editing only the original refind.conf file by adding Debian option solve the problem, too? Maybe it could be added to the next release of FOG out of the box, because Ubuntu is already there.

I guess I have 2 points here.

We created a second exit mode for refind in case the settings you have in the second refind conflict with efi exit booting for other hardware. If what you have in this second refind.conf file is acceptable for all of your computers on your campus then these edits are unnecessary. I didn’t know to what extent you would need to adjust the original refind.conf file (possibly we should have started there and then decided to go the hack path).
The FOG programmers have to keep the configuration generic so that it works for the largest population of hardware. Most don’t want an additional menu after exiting from FOG. I personally would like to see a few extra UEFI exit modes included in the FOG base so for unique hardware this process you did could be used by picking an alternate refind.conf file.

If updating the default refind.conf works for you and its good on all of your hardware, then just update the global UEFI exit mode in the FOG Configuration->FOG Settings panel.

@george1421 Great, thank you

Hi there,

this might be exactly what i’m looking for, creating two refind exit options, one to windows, one to ubuntu.

I’ve followed your steps belo but i’m getting the following error when tryinig to use the newly created REFIND_EFIX2 option

george1421 · Oct 18, 2021, 8:24 AM

@chris_unit well I don’t think its an exit mode that is causing what is in your picture.

Based on the error I’m going to guess at this.

Your computer is a uefi based one since you are using refind.
Memdisk is a bios based program that will not run on a uefi system.

You have apposing conditions here so the error message is understandable. Exec format error. That’s unrelated to the hack a proposed below.

chris_unit · Oct 18, 2021, 2:35 PM

@george1421 yes we’re are trying to be uefi across the board

so should we undo all the steps to create the for efix2 or is this still useable in a fully uefi system?

i’m not sure why memdisk is getting involved. is that part of refind?

the original refind option boots perfectly into windows, surely we’ve just created new option in fog which runs a duplicate config file which is identical to the original?

@chris_unit

No on the undoing steps.

the default refind is configured correctly for windows. What you need to do for the refind 2 configuration is to configure the refind2.conf file so that it ONLY looks for the second OS so it won’t see windows and try to boot it.

george1421 · Oct 18, 2021, 3:50 PM

@chris_unit what you posted looks right, but also remember that its been several months since I tweaked the code. If I remember right there was another spot in the code that needs to be updated to use the variable you just created.

chris_unit · Oct 18, 2021, 6:24 PM

@george1421 i’ve attached the two files if that helps (added txt to the end of the file name to allow upload)

bootmenu.class.php.txt service.class.php.txt

george1421 · Oct 18, 2021, 6:47 PM

@chris_unit are you seeing a specific issue? If you have a coding issue the webui will become unresponsive. If the web ui is working without issue then you need to look into the config files to get them to do what you want.

note: I’m traveling for work at the moment so I’m going to be on and off for the next week.

chris_unit · Oct 18, 2021, 7:20 PM

@george1421 hi there

yes the issue is the photo i sent.

I’ve followed your below steps and with refind.conf being identical, refind_efix2 doesn’t work so it must be a syntax error as all we’ve done is create an identical button?

chris_unit · Oct 18, 2021, 8:09 PM

@george1421 i’m getting the following error when i try to use REFIND_EFIX2

george1421 · Oct 18, 2021, 8:23 PM

@chris_unit I’m confused because the pictures you’ve posted mentioned memdisk. memdisk should not even be in the picture at the moment. memdisk is not compatible with uefi.

So lets try to debug this a bit more to see if its doing what we need. I want you to change in the FOG Configuration -> FOG Settings Expand all button. Now search for “uefi” you are looking for uefi exit mode or something like that. The default should be refind. Change that to the refind2 exit mode. Save the settings. Edit: also change the exit mode for bios to refind2 (that will give us the right results either way below)

Now I want you to go to this URL with a browser from a windows computer. http://<fog_server_ip>/fog/service/ipxe/boot.php?mac=00:00:00:00:00:00 That will give you the text behind the iPXE boot menu. Copy that text and post it here. We might have to add an additional parameter to tell it the client is uefi. I don’t have access to a fog server to test at the moment. Lets see if FOG is giving us what we need in the ipxe menu.

@chris_unit did you change both the uefi and bios global settings to refind2. That is what my edit in the previous post talked about. We need to pass an additional parameter with the mac address to get boot.php to send out the uefi exit mode. By setting both bios and uefi to refind (temporarily) it should send out the refind2 exit code. If it does then you have things programmed correctly.

@chris_unit ok looking at the menu something is missing in the code. Looking at the ipxe menu I also see how memdisk is getting in the mix here. I’m still traveling so I don’t have access to my home test lab. I’ll have to look over the code you provided to see what bit is missing.

george1421 · Oct 19, 2021, 8:58 AM

@chris_unit in the bootmenu class file.

 self::$_exitTypes = array(
            'sanboot' => $sanboot,
            'grub' => $grub['basic'],
            'grub_first_hdd' => $grub['basic'],
            'grub_first_cdrom' => $grub['1cd'],
            'grub_first_found_windows' => $grub['1fw'],
            'refind_efi' => $refind,
            'refind_efix2' => $refind2,
            'exit' => 'exit',
        );

this

 'refind_efix2' => $refind2,

should be

 'refind_efix2' => $refindx2,

to match this code above

$refindx2 = sprintf(
             'imgfetch ${boot-url}/service/ipxe/refindx2.conf%s'
             . 'chain -ar ${boot-url}/service/ipxe/refind_x64.efi',
