I am running on Live USB and I would like to install aptosid tp an another one with persistent mode- I used the live usb installer tool but the installation stops with grub error about iso9660.
I tried also with fll-iso2usb but same error. The usb stick should be ok, tried it as fat32 and ext2, and boot flagged.

Sorry, here is it

aptosid@aptosid:~$ su
root@aptosid:/home/aptosid# fll-iso2usb -D /dev/sdc -f none --iso /media/disk1part5/home/admin/apto.iso -p -- lang=en_US tz=Europe/Helsinki
O: using partition /dev/sdc1
O: mounting /dev/sdc1 on /tmp/install-usb.VTrPbo
O: mount point ready: /tmp/install-usb.VTrPbo
/tmp/install-usb.VTrPbo
O: installing grub on /dev/sdc
/usr/sbin/grub-setup: error: hd2 appears to contain a iso9660 filesystem which isn't known to reserve space for DOS-style boot. Installing GRUB there could result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup (--skip-fs-probe disables this check, use at your own risk).
E: grub-install failed, root-directory=/tmp/install-usb.VTrPbo, device=/dev/sdc
O: umounting /dev/sdc1 from /tmp/install-usb.VTrPbo
O: mount point destroyed: /tmp/install-usb.VTrPbo
root@aptosid:/home/aptosid#

most probably you dont want to install over /dev/sdc

please show us the output of
      Code:
fdisk -l /dev/sdc

Here. I formatted it also as ext2 and same grub error was a result.


sudo fdisk -l /dev/sdc

Disk /dev/sdc: 4016 MB, 4016046080 bytes
66 heads, 25 sectors/track, 4753 cylinders, total 7843840 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c40f0

Device Boot Start End Blocks Id System
/dev/sdc1 * 2048 7843839 3920896 b W95 FAT32
aptosid@aptosid:~$

Please erase the first sectors
      Code:
  dd if=/dev/zero of=/dev/sdc bs=1M count=16

unplug and plug the device
after that recreate the partition
