Ok, so to sum up: You have trouble booting from disks connected to your
internal SATA controller, but only when another controller (presumably
with disks attached to it) is in the system. AFAICS, we can rule out the
kernel as the cuplrit completely, as grub doesn't even get that far.
I'd say Grub2 and/or your mainboard (unlikely) has a problem that is in
no way related to your upgrade to 6.0.1 (but to stable in general). If I
were you, I would try to get support from the grub people directly.

What I meant was to physically attach disks to different ports.

Meaning "the BIOS doesn't find a boot loader"?

I wouldn't call a new installation a "recovery". For a new installation,
you backup your data, install to new filesystems and restore your
backup. Recovery procedures obviously vary with the actual problem you
need to solve.

Sorry for stressing that again, but "reporting" problems here will not
get the bug fixed. Ever.
I am sorry that I only ask question that apparently lead you nowhere. I
am just stabbing in the dark and I am afraid we will never get to the
source of the problem unless you start from scratch and document every
step you do in detail.
