I want to create a Live USB ..I have the ISO image in the hard disk

I issued

dd if=/path/Pardus-2011.iso of=/dev/sdb bs=4M

Where Sdb is my USB

The copy operation is okay...It says no of records in / out and gives the statistics

But when I boot the system , getting the error:

SYSLINUX: 2003 to 2010 Peter Anvin
No UI or default directive found
Boot :

In some cases , the USB itself is not recognized by BIOS at boot..

My BIOS supports boot from USB ..I have Boot order 1. CD/DVD 2. USB 3. HDD

Also what is the filesystem to be adopted for dd?

I usually format using FAT or FAT 32

I issue

1.mkfs.vfat /dev/sdb -I (or)
2.mkdosfs /dev/sdb (or)
3.mkdosfs -F 32 /dev/sdb

What is the correct way of partitioning USB drive? - FAT or FAT 32....Most Live USB creators (unetbootin/LiLi Live/Usb Creator) recognize only FAT32...

I dont want a Linux filesystem (ext2,ext3 or 4or reiserfs)for my USB as it is not portable across many systems as MS OSes do not read them..Also I had little success in booting a USB when I partitioned it using ext2..I read somewhere that ext2 will not reduce the life of the USB drive compared to other fs.

Probably because it is *not* a hybrid ISO image. If Pardus is based on Ubuntu (which I believe is true) then you can use Ubuntu's usb-creator-gtk or usb-creator-kde to create it.

ok let me think... hmmm....

what about you try unetbootin??? http://unetbootin.sourceforge.net/

it's pretty straight forward. if you managed to use dd you'll definitely manage to run this program and make a bootable usb flash drive with your distro..

@Kenny: Pardus Linux is not based on Ubuntu, it is a independent distro: http://distrowatch.com/table.php?distribution=pardus

But you are right, it seems not to be a hybrid-iso-file, so the OP should follow the advice from silvyus_06.
