I spent about 7 hours working with the above wiki and diverting to other solutions involving chroot programs that were nonexistent on the Internet because they were probably removed. There is no real problem with the instructions. They worked perfectly for me once I had read something on a grub wiki. You said:
For BIOS Systems
1. Install a new GRUB bootloader with the following command ( Modify to match your system )
What I and probably many others failed to understand was that this was not the partition. It was the label of the disk with the partition. The wiki was very specific in saying this and once I saw the wiki I saw how dumb I was. Abstract computer writing may work for those used to reading it all day long. It would have been a big improvement if you put a little note** The Disk NOT the Partition with Grub. Looking at the number of people who have had problems with this task I have a bad feeling I am not alone in misinterpreting this.
