Comment 41 for bug 1885414

Bootloader installation still fails with Aug 06, 2020 ISO of Ubuntu MATE Groovy 20.10 in a VirtualBox VM.

Host OS: Ubuntu MATE 20.04
VirtualBox Version: VirtualBox-6.1.97-139689-Linux_amd64

Right when I tried to partition manually there were warnings that I never saw up until Ubuntu MATE Focal 20.04

Warning #1:
"No EFI System Partition was found. This system will likely not be able to boot successfully, and the installation process may fail. Please go back and add an EFI System Partition, or continue at your own risk".

and upon clicking "Continue", installer displayed:

Warning #2:
"The partition table format in use on your disks normally requires you to create a separate partition for boot loader code. This partition should be marked as a "Reserved BIOS boot area" and should be at leat 1 MB in size. Note that thi is not the same as a partition mounted on /boot.

If you do not go back to the partitioning menu and correct this error, boot loader installation may fail later, although it may still be possible to install the boot loader to a partition".

I have submitted 2 similar bug reports on July 06, and Aug 01, bug report #1886580 and #1889989.

Today, I could not submit bug report from within the installation as Apport kept displaying a message, "Collecting problem information". I waited for 20+ minutes but it did not bring a window from where I can submit a bug report.
