CD image on a flash drive

There is a huge desire to download the liveCD with the external drive.
Grub4dos can do such things, provided that the iso image will be continuous.
For grub-a find that's the instruction:

1) create a cd sized partition (700 gb or slightly larger) or a dvd sized partition (4.5 gb or thereabouts).
2) format the partition iso9660 (in essence, creating a cd disk on the hard drive).
3) burn the iso to the new partition just as you would burn to cd, specifying cdrom=/dev/hdX,Y (the partition on the drive instead of the cd drive).

The first step is elementary, but 2 and 3 do not know how.
Probyval use dd, but the resulting images are not loaded, and again taken to the grub-menu as well.
wodim uses syntax dev = / dev /..., not cdrom = / dev / hdX, Y. What to write?

For example:
The first image on sdc3, second on sdc4. Recorded with the help of dd. Disks are mounted, are visible.
When booting from external drive, grub on the command root (hd0, 2) or root (hd0, 3) gives: "Unknown file system type 0h83 and return to the menu.lst.
I looked through the possible types for the partition, iso9660 or the like is not found.

Or maybe a Russian one

sdc3 should be (hd2,2)

Re: CD image on a flash drive

When booting from a flash drive sdc3=(hd0,2).
In addition to these discs, I still load the archlinux with the first section sdc1 as (hd0,0). tongue

USB_stick. Well, I have written in the first post that he used the dd and I did not get.
