Found the issue. Do the following: > sudo debconf-show grub-pc > sudo dpkg-reconfigure grub-pc The last screen sets the default GRUB device(s).

[Bug 1769404] Re: grub is installed to /dev/sda by default and fails
So, the undocumented "GRUB_DEVICE" may be the answer. I could only find it in a Gentoo post: GRUB_DEVICE (detected) Device node for the volume containing the root filesystem. Set this to override the grub2-mkconfig command's root device auto-detection. For example, GRUB_DEVICE=/dev/ram0 will force root=/dev/ram0 to be used in the kernel command line. While it clearly exists: > grep DEVICE -A40 /usr/sbin/grub-mkconfig it is not documented in the standard: > https://www.gnu.org/software/grub/manual/grub/grub.html I will test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769404 Title: grub is installed to /dev/sda by default and fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1769404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1769404] Re: grub is installed to /dev/sda by default and fails
Ok, UUID is only for partitions, so maybe the serial number instead. This error crops up when a new kernel is installed during an update/upgrade. The update-grub command is called which in turn may call grub-install. It seems to always default to /dev/sda instead of the where the sdX grub-install was told to install. Can grub-install store the last /dev/sdX it was told and use it as default?

[Bug 1769404] Re: grub is installed to /dev/sda by default and fails
Bin Li is incorrect. The boot order may not determine the allocation of /dev/sdX for any number of hard drives. In general, IDE drives will always be assigned first and SATA drives will be assigned second. If you are booting from a SATA drive and have 2 IDE drives, you will always get /dev/sda to the first IDE, /dev/sdb to the second IDE, and /dev/sdc to the SATA drive NO MATTER HOW YOU SET THE BIOS BOOT ORDER. Therefore, grub should have a hint, option, or other setting to point to the "default" and not assume /dev/sda. A better way would be to use UUID like in the fstab file since /dev/sdX assignment may not be guaranteed. ** Changed in: ubiquity (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769404 Title: grub is installed to /dev/sda by default and fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1769404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, Bin Li. Thanks for your answer. Do you mean it's not possible for ubiquity to identify by itself the first disk in boot order without touching manually advanced partitioning tool or there are some other purposes to choose /dev/sda for grub by default? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769404 Title: grub is installed to /dev/sda by default and fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1769404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1769404] Re: grub is installed to /dev/sda by default and fails
It depend on the boot sequence of your BIOS. If the SSD is the first one, and you install the grub on HDD, you can't boot up into HDD. You need change the boot order. Or enter the boot menu with F12, after that select HDD to boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769404 Title: grub is installed to /dev/sda by default and fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1769404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
