Did you decrypt via cli or from another method. I've been trying luksopen the running chroot-helper but get prompted drive is already in use. Might need to chroot manually

Well, I do not have an encrypted harddrive, so I can't test it
But I think you are right, you have to chroot manually, sorry folks.

If you are in your siduction system and since your system is using efi, a simple

Code: [Select]
grub-install
is needed.

Whatever I have try does not work
For example

Code: [Select]
grub-install
Installing for i386-pc platform.
grub-install: error: install device isn't specified.

Quote
# grub-install /dev/nvme0n1
Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

@titan
The files will be overwritten by the new release and you have to repeat the quick and dirty fix.
Most of the time the problem can be resolved by a grub-install, but it depends
on the ability of the scripts to find the grubx64.efi loader. esp. on dual boot
systems different from a vanilla siduction install. Once successfully booted run a
"efibootmgr -v" command, i.g.:

BootCurrent: 0005
Timeout: 1 seconds
BootOrder: 0005,0001,0000,0009,000A,000B,000C,0002,0003,0004,0006
Boot0000* debian        HD(10,GPT,14336d57-7fb1-49b6-92ff-b4a20578619c,0xcfe058b0,0x32000)/File(\EFI\debian\grubx64.efi)
Boot0001* CD/DVD Drive  BBS(CDROM,,0x0)...
Boot0002* Hard Drive    BBS(HD,,0x0)...
Boot0003* UEFI:CD/DVD Drive     BBS(129,,0x0)
Boot0004* UEFI:Removable Device BBS(130,,0x0)
Boot0005* UEFI OS       HD(10,GPT,14336d57-7fb1-49b6-92ff-b4a20578619c,0xcfe058b0,0x32000)/File(\EFI\BOOT\BOOTX64.EFI)

I boot siduction with secure boot enabled (although I dropped the sec policies afterwards):

$ mokutil --sb-state
SecureBoot enabled

The replacement of  modified BOOTX64.EFI by the standard unsigned grubx64.efi would therefore have resulted
into a complete disaster.

Hence in your case find the recent grubx64.efi  bootloader with the above command and replace it manually
by the new one, if update-grub fails for some reason.

@sotnig:

> Installing for i386-pc platform.

In your case grub-install is detecting your platform as legacy
and could not find space on the disk for the bootloader. Are you
sure you have uefi enabled in the BIOS?

I think it is legacy. I will  check and correct and I will let to you know what happens.

In the meantime you can also do a

$ sudo fdisk -l /dev/nvme0n1

and post the output to see whether you have
a GPT or DOS formated disk and ESP or BIOS partition.

You haven't mounted your efi partition as /boot/efi, that's why grub-install will fail!

On an efi system, propper mounting of efi partition is indeed needed!
And since you have 2 efi partitions, you have to use the right efi partition!

And btw, if you want really help, you should exact explain, what you are doing.
