I am trying to retire an old HD where grub /boot directory happens to
reside, so I am trying to move it to the current Linux root partition which
is on an SSD.
this is the script used to provide a Windows boot option in the Grub menu:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
#!/bin/sh
exec tail -n +3 $0
menuentry "Windows 10" {
insmod fat
insmod chain
insmod part_gpt
set root=(hd1,gpt3)
chainloader /efi/Microsoft/Boot/bootmgfw.efi
}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
the problem is that when trying to pick this option from grub menu when
booting from the new location, it reports 'error: invalid signature'. The
same menu worked fine when it was booting from the old disk (I made double
checked that (hd1,gptr) points at the correct partition).
I searched this list and found this thread:
http://lists.gnu.org/archive/html/help-grub/2016-05/msg00020.html but am
not quite sure how to apply this to the Windows case.
TIA!
