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
