[Bug 1772429] Re: dual booting couldn't write grub boot loader during install

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the installer in EFI mode. You either need to boot the installer in bios
mode, or partition the disk using GPT and set up an EFI system partition
to install in EFI mode. This will be done for you if you choose the "use
entire disk" guided install option.
