This is a Linux-only machine - no dual boot of any kind. The live 18.10 CD ran perfectly from a USB stick.
I have not (yet) tried installing 18.10 with a BIOS BOOT partition set up, but doing this with 18.04 was unsuccessful. A bit of background, which may help (or not). This machine was running 18.04 (with the SSD as / and the HDD as /home) until a recent upgrade, which left me booting to a blank screen. Although the 18.04 live CD ran perfectly, I was unable to reinstall a working system in any configuration (split between the 2 drives, to the SSD alone - with a BIOS BOOT partition set up, or to the HDD alone). This led me to install 18.10, with the result you see. I have now managed to get my system working by installing 18.10 to my HDD alone, but obviously this solution is less than satisfactory. Hope this helps, Ian Thanks for you On 23/10/2018 16:10, Mathieu Trudel-Lapierre wrote: > Thank you for taking the time to report this bug and helping to make Ubuntu > better.
