Ok. That works fine in the BIOS boot mode - I think there ought to be a
warning though! I didn't expect that kind of behaviour - and was
surprised by it. However, yesterday, I spent a long time experimenting
with EFI install to my spare drive. The components of grub are
installed to sdc, but sda holds the pointer to it in a specific sector.
Out of five installs, only one of them would boot. All the rest gave
the grub error (from sda boot) "error - no such device" - followed by a
UUID. I assume that the UUID quoted is meant to be the UUID of the
FAT32 EFI partition on sdc. I checked that, and it was not the same.
If the BIOS boot is meant to be working as it does, I have to accept
that, but the EFI boot system does seem to have a problem!

Title:
Incorrect installation behaviour on multi-drive system
Status in ubiquity package in Ubuntu:
Invalid
Bug description:
I have a PC which has two internal hard drives. One of them (sda)
currently has an installation of Mint, and the other (sdb) contained
an installation of 15.04 at the time of this problem.
I made a DVD from the testing iso of 15.10 last Wednesday. On booting
from this DVD, I was taken to what looked like a grub screen which
included the option to carry out an OEM installation. I selected
'Install Ubuntu'.
I took the option 'Erase disk and install Ubuntu', and chose sdb as
the install disk. At the beginning of the installation, I was given a
warning notice telling me that the new installation might not be
compatible with the legacy BIOS installation it had detected on
another OS (Mint, I assume). I let the process continue.
The installer requested that I restart the system and ejected the DVD
as normal. On restart, I first allowed the normal grub screen (from
sda) to appear. This was my normal, unaltered grub screen, so I then
re-boooted, and used the BIOS boot menu (entered by pressing the F11
key on my system) to boot from sdb. It failed with just a cursor. It
seemed to indicate that sdb was not bootable. I booted from the grub-
screen into Mint, and used update-grub to make the grub menu pick up
the Ubuntu installation, which it did.
At this point, it had not affected sda at all. I had to update grub
manually on sda to get into Ubuntu at all.
The installer seemed to have put grub onto sdb - on a separate boot
partition. The grub.config file appeared to be correctly formed. Why
it would not boot when I selected sdb, I have no clue at all.
After that, I installed grub as a legacy bios boot, first onto the
existing FAT32 partition, and then onto the same partition formatted
ext4, and finally after deleting the boot partition entirely,
installing grub to the main system ext partition. I had no success
with any of these, except to drop me into an emergency terminal when
booting from sdb. The x-server was not available and failed to start
even manually from the command line.
When I decided to re-install, everything was the same as before, but
the warning did not appear at all, and neither did the initial grub
screen. Grub was installed to sda only, and sdb was not at that time
made bootable. I did this manually later. I didn't understand why
there should have been any change in behaviour. Happy to answer any
more questions, I did not make an exact record of any error messages
first time around as I had assumed that re-installing grub to sdb
would fix the problem.
I recorded the exact process on the second installation:
1) Boot from DVD.
2) Select 'Install Ubuntu' from the first partition.
3) Followed defaults after selecting 'Erase disk and install Ubuntu', and selecting sdc as the disk to be erased.
At no point was there anything to ask where I wanted grub to go. I
think this can only be done from the manual install screen. On the
second occasion, there was no message about the boot not being
compatible with legacy BIOS.
After the requested restart at the end of the installation, grub had
been installed and updated to sda, and showed Mint, and the two
installations of Ubuntu (the one on sdb and the one on sdc). sdc
itself had not been made bootable.
That does not explain why it would not boot off sdb the first time,
but it is may be too late to work that out now.
