Can't install Debian without dedicated /boot partition
I'm trying to install Debian Stretch with full disk encryption
(LVM-on-LUKS). But when the installer is trying to install Grub in
crashes with the following error message:
Unable to install GRUB in dummy
Executing 'grub-install dummy' failed.
This is a fatal error.
The disk is partitioned with an 512MiB (specified in bytes) EFI
partition and the rest in an LUKS encrypted container. The container
contains a LVM volume group with a swap partition and a root partition.
I'm able to install NixOS with GRUB without needing an separate /boot
partition. So I believe it isn't a limitation in GRUB. Can't find any
information in the documentation that says that a separate /boot
partition is mandatory.
The ISO is written to the USB memory using Etcher with verification
turned on. It was verified using SHA512 sums, which itself was verified
with the GPG keys. I also ran the tool inside the Debian installer for
verifying the installation media. The image I use is the netinstaller
for Stretch (version 9.5).
Should I be able to install Debian Stretch without a separate /boot
Thanks in advance!
