>From memory. Fix for reality. Partition and format your USB (if you are using an old fdisk, start at sector 8 or later). Format as ext3. Mounting as something like '/mnt/fai_usb' and the iso as '/mnt/fai_cd'. Assuming /dev/sdb1 as your formatted USB device
mount -o loop /path/to/iso /mnt/fai_cd mount /dev/sdb1 /mnt/fai_usb rsync -avp /mnt/fai_cd/. /mnt/fai_usb/. cd /mnt/fai_usb/live/filesystem.dir mount -o bind /proc proc mount -o bind /dev dev mount -o bind /sys sys chroot . /bin/bash grub-install --no-floppy /dev/sdb (This may take a while if the buffer is still syncing) exit umount proc sys dev cd /mnt umount fai_usb And there you go!
