[Bug 1906958] [NEW] install crashes when installing boot loader on dual bootsystem

[Richard Antholine]

Public bug reported:

I first deleted partitions on 4T HD so I could install Ubuntu 20.04 LTS
on its own HD.  Tried direct install from CD and crashed when trying to
install boot loader to /dev/nvmeOnp1. I believe this is where the
Windows 10 Home boot resides. It Froze the system and would not quit.
Had to hard power off, power on and rebooted to Windows without problem.
Tried "Try Ubuntu" and using the icon to install.  Crashed same place.
Tried again installing, crashed same place but this time it permitted me
to report error. I have used older versions with this Windows 10 Home
with no problems using same hardware.
