The debian-efi example VM throws you into the EFI shell once built.

[Folaht]

Overview of the Issue

The boot command is written to get out of the EFI shell
and the end result despite having installed grub,
still throws you into the EFI shell.

Reproduction Steps

packer build efi-debian.pkr.hcl

Plugin and Packer version

1.0.9 & 1.9.1

Log Fragments and crash.log files

I don't think this is a crash log issue.

Maybe remove the efi_firmware_vars, it will not boot. It only can use above 7.0

[stefangweichinger]

I think I hit the same issue. Is there a solution already? thanks
