[Bug 1942369] [NEW] installing Ubuntu 20.04 on Win 10 dual boot and fatal error at grub/something

Wed Sep 1 20:19:43 UTC 2021

Public bug reported:

Installing 20.04 LTS from USB hoping to dual-boot Windows 10. Install
did not recognize that Win 10 was already there, so I installed as
"Something else" and allocated the necessary drives from free space:
/home, /boot, Swap area, and root /. Before install started, told me to
go back a create a 256MB EFI partition which I did.

Install failed well in with the following:

Executing 'grub-install /dev/sda' failed.
This is a fatal error.
