Ubuntu 20.10 install fail because of grub install failure

[florin]

Installing latest Ubuntu 20.10, at the end, install grub fails and so does the Ubuntu installation. I use legacy BIOS, not EFi, but for some reason, in the installation EFI is mentioned. I tried also toram option (but did not remove the USB drive I was installing from) to test what some other user found to be a solution, for me, with USB drive in, it did not work. I will be back with a photo of the messages.
