Re: multiboot 2 HD

[Steven I Usdansky via users <users@xxxxxxxxxxxxxxxxxxxxxxx>]

I deleted the 30_os_proxy file. It was giving me duplicate entries. 

Below is my /EFI/fedora/grub.cfg. Each disk's efi partition contains a copy. I use efibootmgr to select which disk's /EFI/fedora.grub.cfg  to use when the computer is powered on. Changes made with Fedora's efibootmgr are not permanent on my machine, so I use Ubuntu's. The efi partition's grub.cfg then chainloads /boot/grub2/grub.cfg for the distro I want to boot. 

# my semi-ideal grub.cfg

### BEGIN /etc/grub.d/06_grub-customizer_menu_color_helper ###
set color_normal=light-blue/black
set color_highlight=yellow/brown
### END /etc/grub.d/06_grub-customizer_menu_color_helper ###
