I was wondering if I could simplify the commands used for installing GRUB on a
removable drive.
As shown in the following link, I chroot into a mounted partition to run
grub-install and grub-mkconfig on it:
chroot not required.
1. Boot into any linux OS with grub installed.
2. Check that the packages are installed (should be)
libisoburn
efibootmgr
dosfstools
some OS name libisoburn packages differently; if unsure, install
'xorriso' package that contains it.
3a. for a plain grub prompt usb
grub-mkrescue -o anyname.iso
burn anyname.iso to the usb
3b. to include a current working grub.cfg in the usb
mkdir -p ~/burn/boot/grub
sudo grub-mkconfig -o ~/burn/boot/grub/grub.cfg
sudo grub-mkrescue -o anyname.iso burn
burn anyname.iso to the usb
