@sebastian-roth With exit style of “exit” I get Chainloading Failed, with the exit type set to system default (REFIND_EFI) or manually setting it to REFIND_EFI I get the attached screen shot

The machines giving me trouble are Dell Alienware aurora r6 running bios version 1.0.8. I have a bunch of other Alienware aurora r6 running bios version 1.0.3 which have been working great with FOG. I am also in contact with dell regarding this bios revision (1.0.8).

I am running the latest working branch “Running Version 64 SVN Revision: 6079” pulled this AM. I have my machines set to PXE boot in the bios. On my newest batch of Alienware desktops after imaging every boot returns the rEFInd - about screen if it attempts to HD boot. I have tried all the options under “Host EFI Exit Type” Any other suggestions? All my other systems seem to still be working fine.
