This sequence doesn’t seem to work for me. I continue to receive the following (on the first step):
grub2-install: warning: Attempting to install GRUB to a disk with multiple partition labels. This is not supported yet…
grub2-install: error: embedding is not possible, but this is required for cross-disk install
After I receive the errors, I still ran steps 3 and 4…the grub2-mkconfig doesn’t seem to fail…but it doesn’t seem to do anything. The computer still hangs at “Booting from Hard Disk”.
