“executing grub2-install install failed /dev/sda *reloaded

Ask Ubuntu Asked by brad on January 23, 2021

I am trying to install Ubuntu 20.10 using a custom partition setup on my /dev/sda device. I can install Ubuntu fine using the defaults, but I do not want defaults. I want a larger /boot sector.
Upon creating a custom /dev/sda1, /dev/sda2, /dev/sda3 and /dev/sda4

I am getting the exact same error as this guy

same error

But none of the solutions work. There is no

automatically install to MBR of first hard drive

Option.

Dell Inspiron 7359

UPDATE:
