Public bug reported: my HP Proliant ML30 Gen9 PC has some sort of built-in software RAID that requires UEFI. Installing Ubuntu to the existing Windows "mirrored" drives resulted in not being able to boot Windows and Ubuntu.
Next I bought a 3rd hard drive, did not set it up with any mirroring or anything. Booted in UEFI mode again, and chose "something else" in the Ubuntu installer to install the bootloader to this new 3rd hard drive, and I also set up swap, root, and UEFI partitions. Near the end of the DVD-RW installation, it told me that it was "unable to install grub to /dev/sdc" (sdc=third hard disk)... "Executing grub- install /dev/sdc failed. This is a fatal error." Then the installer took me her to fill out a bug report. This was a 16.04.01 Ubuntu-Gnome DVD-RW installation.
