[LINUX] Install Grub on USB memory (UEFI) ~ grub installation ~

In the above, we prepared the USB memory. Finally, grub will be installed. Enter the following command.


$sudo mkdir /mnt/boot                       #(1)
$sudo mount /dev/sdc1 /mnt                  #(2)
$sudo grub-install --target x86_64-efi --debug --efi-directory /mnt --boot-directory=/mnt/boot --removable      #(3)

Enter the last command to start installing grub (characters flow at a tremendous speed, but don't rush). At the end, a No eroor reported message is displayed. By the way, I will briefly explain the above command (you can skip it)

1 ・ ・ ・ Create a new room called "mnt" in your area (/ user name / home), and create a "boot" in that room.

2 ・ ・ ・ Link the "/ dev / sdc1" created above with the room "mnt" created in # 1 (the room "boot" in "mnt" is also linked). In other words, the files installed on "mnt" are automatically sent to the partition "/ dev / sdc1" in the USB.

3 ・ ・ ・ Install grub in / mnt / boot. Since "/ mnt" and "/ dev / sdc1" are linked in # 2, grub is installed in USB.

This completes the USB installation of grub. Next article shows how to boot Linux from grub.
