This is not good. It means there is no grub.cfg. for your sda5 (boot)

Worse, your boot files vmlinuz and initrd are not there either.

Here, I was hoping we can force to make boot files from your sda8 to 
sda5,(and set sda5 boot to sda) but apparently it failed.

This is if we succeed, we ensure grub.cfg is there, especially for the 
sda5 entry.


Okay, Niels, maybe ... it's the encrypted partitions that you set up 
preventing access to sda5. I don't know. But ...we can still try to copy 
the boot files from sda8 to sda5 the old fashioned way, taking care to 
set the correct UUID number of sda5 or just /dev/sda5 or 
root=LABEL=xxxxx, I wonder though if you can do this when the partition 
is encrypted causing the same failure as before. Do you want to try this 
out? Let us know how it turns out.


Perhaps my buddy, Tom H, can put in some input? He had given me some 
pointers lately, he may throw some light on this.

Take care, good luck.
