When installing GRUB on a new VM that I partitioned with parted, I got the following error:
grub-install: error: will not proceed with blocklists.
The solution was to set bios_grub flag on the partition:
parted /dev/sda set 1 bios_grub on
Some people say that you also need to remove the boot flag from the partition:
parted /dev/sda set 1 boot offDo this before setting the bios_grub flag.
