Make USB Stick Bootable
Original post is here eklausmeier.goip.de/blog/2017/03-15-make-usb-stick-bootable.
In various forums one reads that one should use dd
to copy a ISO image to an USB stick. Although this works, more often you do not want to use a ISO image but rather copy a Linux system at hand. First you mount the root filesystem of the new USB stick, then mount /boot within a chroot
. Finally use grub
commands. I.e., type
mount /dev/sdc2 /mnt/stick
arch-chroot /mnt/stick
mount /dev/sdc1 /boot <--- /boot is local to chroot!
grub-install --target=i386-pc --boot-directory=/boot /dev/sdc
grub-mkconfig -o /boot/grub/grub.cfg
umount /boot <--- umount "local" /boot
Also see GRUB in the Arch Wiki.
Setting the bootable flag in the partition table one either uses gparted
, a graphical tool, or, as the task at hand is so simple, one just uses parted
.
parted /dev/sdc
set 1 boot on
print
Unrelated, but often useful. Just in case you changed something in the initial RAM disk, use
mkinitcpio -p linux
