Hello all, I am very confused by grub-install. I am trying to install a livecd on my USB pen, (Knoppix, sorry, using www.knoppix.net/wiki/USB_Based_FAQ), and get to a line: grub-install --root-directory=/media/wjm-live --no-floppy '(hd0)' This gives the error: mkdir: cannot create directory `/media/wjm-live//boot': Permission denied This does not seem to be true. I tried copying grub-install to /usr/local/sbin/grub-install-wjm to edit it and try to see what is going wrong ...and the error vanishes! but then I get /media/wjm-live/boot/grub/stage1 not read correctly and somehow I suspect this may be related to the original error. Can anyone suggest what might be wrong? Thanks, Bill
