crash at end of installation procedure

[Michael Dooley]

Unable to write grub to sda. My bet is that I should have indicated some sort of UEFI set-up. Just a guess on my part.

Status changed to 'Confirmed' because the bug affects multiple users.

Anyone know how to finish the installation?

A UEFI partition seems to be a requirement when installing 20.10.

Create a 50 to 100 Megabyte partition using Gparted and flag it as boot and esp. Then select this partition and change it to EFI System Partition. Finally select a root partition and perhaps a data or home partition. I installed grub to /dev/sda.

Installation on two laptops proceeded without crashing after creating a UEFI partition.
