grub-install problem

[Bob]

I have two partitions with Ubuntu installed on my computer.  SDA3 is my normal
system, SAD7 is a test system.  Whenever I update the test partition if grub is
also updated I need to run "grub-install --force" on my normal system, SDA3, to
get it to be the defaupt boot partition.

Today after updating SDA7 it updated grub so SDA7 was the default boot
partition.  I booted SDA3 and ran "grub-install --force" which did not work see
the following.

robert at MARS:~$ grub-install --force
Installing for x86_64-efi platform.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: warning: disk does not exist, so falling back to partition device
/dev/sda1.
grub-install: error: disk `hostdisk//dev/sda1' not found.
robert at MARS:~$ 

I then tried just "grub-install" which normally does nothing because grub is at
the latest level and got the same error messages.  I do not understand why grub
is checking SDA1 because it is the EFI partition.  The bios_grub partition is
SDA2.

What is going on?
