No Grub, No boot when using the System Encryption

No Grub, No boot when using the System Encryption
I'm testing Neptune 6 beta "buster".for the first time. The computer won't reboot after the installation is completed if I choose the "system encryption".
I get the following error:
Error: no such device: d02228533-87ba-4a70-1f4f-193838898d2a6eb23.
Error: unknown filesystem.
Entering rescue mode.....
grub rescue>

How ever, I can boot just fine if I don't encrypt the system. So the encryption part is broken.

RE: No Grub, No boot when using the System Encryption
Thanks for reporting this issue.
Can you tell us in more details what you clicked to encrypt the partition.
Which ISO you tested (the name please as it indicates the date aswell because after the first beta we released some newer ISOs aswell).
Do you still have some installation logs in /var/log on the encrypted non booting system?
Is the decrypting of this partition working with the live system?

@leszek,

The problem is that you can't even login at all if you check the encryption box through the installation process. You get the error message when you reboot. So I can't provide you any log. I downloaded the ISO the same day I reported this issue. Please let me know if there is a particular ISO that you want me to test it again.

Thanks,

So you are not able to mount the installed system via the live system?

Correct. The ISO is the latest available on the website.
Neptune6-Plasma5-20190404.iso
You'll run into the issue I reported if you check the encryption box the during the installation process. I reformatted the hard drive the second time, reinstalled and did not check the encryption box, and it boots just fine that way. There were over 400 updates after I reinstalled without the encryption. So perhaps you should make a new ISO available so I can test it again.

RE: No Grub, No boot when using the System Encryption
The new ISO worked. How ever, after you enter the encryption key in order to "decrypt" the system, it takes about 18 seconds to get to the boot screen "select an os to boot". After that is goes fairly quick. On the other hand, same thing on Kubuntu 19.04 which is my current OS, it takes about 5 seconds to get to the login screen after you enter the encryption key.

I hope there is room for improvement to decrypt the system a little faster.
