I need to reconfigure grub to use a different install device. Other threads indicate that there will be a screen that prompts me to select a device:
- How to select GRUB install device
- How should one set the grub-pc package’s “install_devices” debconf setting?
However, no such screen exists. It exits after the 2nd one.
How do I select the boot device?
After Screen 2
Update: The bug has been confirmed and triaged as high priority against basically all supported versions of Ubuntu.
Update #2: Fix has been released for Focal and Groovy! I’m hoping someone on the Ubuntu team is tracking Bionic.
Update #3: Fix has been released for Bionic!
