I had my /boot on a USB, which was configured as a physical volume with two logical volumes. My root disk is fine, but I need to recreate the USB with grub and /boot, including kernel(s) and initramfs. Anyone have a suggesting of what path I might follow?
Boot into a live system. Open you system partition in Nautilus and copy the path (
ctrl + L shows you the path). Then:
sudo gedit [path you copied]/etc/fstab. In the file that opens, remove the line with
/boot in the middle, save and close. Then unmount the partition in Nautilus.
sudo grub-install /dev/sda sudo update-grub
Assuming your system partition is
/dev/sda. You can easily find this out by entering
sudo fdisk -l. It will give you some output with one for every physical drive (like your HDD or your USB stick) and something like
Disk /dev/sda: in the beginning of every block.
