I wonder if you have been bitten by "grub-efi-amd64-signed bug:
hardcoded link -> unbootable system" earlier on this mailinglist.

When you have a separate /home partition I would go for the manual
partition route and leave this partition alone. After installing and
stable boot you can add the home partition manually in /etc/fstab and
have all your brothers settings back.
