Host EFI Exit Type - Refind EFI

[Florent]

Hi,
What “Host EFI Exit Type - Refind EFI” exactly doing ?
I have a weird behavior here. If computers boot on pxe with no fog image task and with “Host EFI Exit Type - Refind EFI”, Bitlocker always ask me the recovery key.
My problem is the other options of “Host EFI Exit Type” does’nt work for me because show error chainloading and reboot after 10 seconds.

Have you an idea ?

@florent rEFInd should not mess with bitlocker at all (at least what I’ve seen). I have seen computers trigger bitlocker on themselves for no apparent reason.

So if you change the boot order to hard drive first does the device function normally?

Is it just one model of computer doing this or all models of computers that boot through FOG?

@george1421 Yes if i change boot order and set hard drive first it’s okay.
Do the problems for many models HP & Dell.
On a model I try to set exit type to “Exit” it works, but do you think it will work same on all ?
On other model with “Exit” option if i have not active tasks it stay on “chainloading failed” and reboot after 10 seconds.

@george1421 Do you think it’s possible to have an option “Reboot” ? Where i can set this to try ?

@florent Is it possible to add a Reboot exit mode? Yes. You will need to make some adjustments to the FOG php code to add this feature.

Before you do that I want you to try something. I see that refind has updated its program. I think the last version that ships with FOG is 0.11.4, I see that refind has 0.13.3.1. I would like to see you try a later version of refind, maybe it has fixes to in it to resolve your problem.

https://sourceforge.net/projects/refind/files/0.13.3.1/

download refind-bin-0.13.3.1.zip In the zip file in this directory refind-bin-0.13.3.1.zip extract refind_x64.efi and refind_ia32.efi

Move these to the FOG server in /var/www/html/fog/service/ipxe directory. But before you move them rename the original files in case the new files do something that breaks exit modes with FOG. Lets see how / if the new version of refind manages the new hardware.

@george1421 Yes i already try this. Works fine but already my problem with Bitlocker.
Actually my problem is our computers are configure to boot on pxe when receive wake on lan.
And Bitlocker ask recovery key if order boot has changed.
But i notice if i reboot “normally” even after that, Bitlocker don’t ask recovery key Bitlocker.
My problem is for our computers “Refind EFI” is the only mode who work with pxe. If i use other option, i have an error like “Chainloading failed”.
This is why i was thinking to have a “reboot” mode, because i don’t find how to make it work the “Exit” mode
