Grub menu missing Windows entry on dual boot Luks encrypted installation

Support and Help
21

Remember, I’m not using LVM. Second, I encrypted the partition only after starting with a manual installation using only /, /boot/efi, and /boot. I used the following to encrypt /dev/nvme0n1p8.

sudo cryptsetup reencrypt --encrypt --type luks2 --hash sha256 --pbkdf pbkdf2 --reduce-device-size 32M /dev/nvme0n1p8

Later I did

grub-install --target=x86_64-efi --efi-directory=/boot/efi --boot-directory=/boot/efi/EFI/ubuntu --recheck

and

grub-mkconfig -o /boot/efi/EFI/ubuntu/grub/grub.cfg

according to the guide.

Does that make it make sense?

In the guide you do a chroot into your decrypted install. Step 3
And add this into grub. /etc/default/grub & update grub to include that.
GRUB_ENABLE_CRYPTODISK=y
I did not see this which is required for updates to be in grub.cfg.
sudo update-grub

Leaving for vacation tomorrow AM, will not be back until Sat night.
Is it still vacation when you are retired? Or just another trip?

I went ahead and and added the line followed by sudo update-grub. I had skipped that before as the guide said it wasn’t needed since my /boot was separate and unencrypted.

Ha, ha! Have a good vacation! Definitely vacation!

Hi oldfred. Hope you had a good vacation. I’ve gone back to Debian. Didn’t want you wasting your time researching this. Thanks anyway.
