Install syslinux
aptitude install syslinux
Totally wipe the USB device. Faster:
dd if=/dev/zero of=/dev/sdb bs=4096 count=35 dd if=/dev/zero of=/dev/sdb bs=4096 count=35 seek=$(($(blockdev --getsz /dev/sdb)*512/4096 - 35))
Safer:
<pre> dd if=/dev/zero of=/dev/sdb bs=512
Make sure the kernel knows about the new partition information.
partprobe /dev/sdb
Maybe partition the damn thing?
# fdisk -l /dev/sdb Disk /dev/sdb: 2003 MB, 2003828736 bytes 9 heads, 40 sectors/track, 10871 cylinders, total 3913728 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: 0x6a204df6 Device Boot Start End Blocks Id System /dev/sdb1 * 2048 3913727 1955840 6 FAT16
Make a filesystem.
mkfs.vfat -F 16 /dev/sdb1
- NO Copy the ISO to the USB device using dd.
- NO
#NO dd if=ubuntu-13.10-desktop-amd64.iso of=/dev/sdb bs=4096 #NO
Again, make sure the kernel knows about the new partition information.
partprobe /dev/sdb
mkdir /mnt/iso mount -o loop,ro -t iso9660 ubuntu-13.10-desktop-amd64.iso /mnt/iso mkdir -p /mnt/sdb1 mount -t vfat /dev/sdb1 /mnt/sdb1 cp -rL /mnt/iso/* /mnt/sdd1/. sync dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb # already done in the initial partitioning. Shouldn't need to do this again. parted /dev/sdb set 1 boot on
old attempts
Run syslinux on the first partition of the USB device.
syslinux -i /dev/sdb1
dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb parted /dev/sdb set 1 boot on
