Hello!
I followed cryptsetup manual to setup LUKS encrypted root partition
https://cryptsetup-team.pages.debian.net/cryptsetup/encrypted-boot.html
- EFI bios
- EFI partition 700Mb
- LUKS encrypted partition containing both / and /boot
- LUKS mapped device directly contains ext4 partition without LVM
To do this I added a second disk, added EFI and root partions on it and
copied all files preserving
attributes and permissions.
I modified files in etc and after chroot I executed:
> update-grub
> grub-install /dev/sdb
After rebooting and disabling first disk (/dev/sda) I was immediately brought
into grub shell
I can notice what there is an error message flashes before booting
"No such device: c740ceea-853c-487c-82ef-3d2138f9a7d7"
I can also "source" (hd1,gpt1)/efi/ubuntu/grub.cfg and it will produce the
same error.
Also cryptodisk.mod module is not loaded.
I can also add insmod ... lines into the (hd1,gpt1)/efi/ubuntu/grub.cfg
but it does not help find partioon using following line:
search.fs_uuid 85030321-f93d-47dc-aa4c-70bf751ad3f7 root
cryptouuid/c740ceea853c487c82ef3d2138f9a7d7
If I try to type ls (hd1
it will show me following information:
grub> ls (hd1)
Possible partitions are:
Device hd1: No known filesystem detected - Sector size 512B - Total size
10485760KiB
Partition hd1,gpt1: Filesystem type fat, UUID C3AC-7168 - Partition start at
1024KiB - Total size 716800KiB
Partition hd1,gpt2: No known filesystem detected - Partition start at
717824KiB - Total size 9767919.5KiB
