executing grub install /dev/sda failed.

[Harry Rocas]

Ubuntu 20.10

Grub installer failed to install on /dev/sda

tried installing grub manually via "Try Ubuntu" terminal.

unallocated all drives. I have 120gb SSD and 250 HDD.

EFI partitioned
Bios partitioned
Swap partitioned
UEFI Mode installation

I think it's an error for both Ubiquity and Grub

The device is Lenovo Ideapad 320 14IAP. Previously installed OS are Windows 10, Ubuntu 20.04.

I tried boot-repair no luck. details are as follows:
