Hello Cesar,
Many thanks for your reply.
I have managed to solve it. I had totally failed to see that I had
messed up the set root entries. After I had deleted both grub_bios
partitions and both /boot partitions and re-created them, I failed to
notice my error for hours, even though it was staring me in the face.
After I solved that I learnt something else about grub. You can only
seem to have ONE boot partition per drive. My setup is so that I have
two separate installations of lfs/blfs on my external drive, and when I
added the second boot partition it went back to the crazy unrecognised
file system error.
Out of shear desperation I copied the kernel image for the installation
I am using to edit the BLFS systemd/gnome book onto the first boot
partition and added a second menu entry for it, commented out the boot
partition in fstab and when I rebooted everything was normal again.
Hopefully this posting will help others who have a similar thought about
adding a second boot partition.
As far as xorg-server 1.16.0 is concerned, its a no go. Even with the
latest stable kernel, and the latest intel driver from the
xorg-developers it just gives a black screen. At least that was an
improvement over the no screens found, but at this stage I have reverted
to xorg-server 1.15.1.
Regards,
Christopher.
