Can't boot to SD OS when insert empty USB driver

[kengyen-chen]

In /boot/efi/EFI/ububtu/grub.cfg
We add "set root(hd0,gpt2)" and remove Search fs_uuid this line.
We find SD will change to hd1 when we insert a empty USB drive, it will can't boot into Linux.

1. How to fix the SD hardware sequence be hd0 ?
2. If SD partition have no FS_UUID, how to config search by PART_UUID ?

Thanks,
Kengyen Chen

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:

1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).

Please also ensure that you include the release and flavour of Ubuntu that you are using.

Please note, bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu.
