> 1) make the first partition active
> 	fdisk /dev/sd[c]1 then a, 1 and w to write and quit

I did this.

> 2) format the usb stick with fat or ext3

I formatted it using mkfs.ext3 /dev/sdc1

> 	(b) ext3 : you will need to use extlinux work on the stick
> 		extlinux /dev/sd[c]1

I mounted the drive and did
extlinux /media/disk

> 4) I extract the isolinux folder from the dvd iso

I copied all the files from 
to the root directory of the usb drive.

> 5) rename all isolinux to (a) syslinux - (b) extlinux

I renamed the isolinux.bin to extlinux.bin
and isolinux.cfg to extlinux.cfg

> 6) copy the dvd/cd iso(s) to your stick

I copied the iso to the root directory of the usb drive.

> 7) normally you should get the same boot loader as when you

I tried to boot off the usb drive and I get a message that
it could not boot the operating system.

Any ideas?
