^ u cant do this to PHYSICAL COMPUTER.

Though u can do it in VIRTUAL MACHINE..

There is no other way then burning it on a CD...

Cant u use a Re-Writtable Disk for instance ?

I know of no way to do it via Windows but via Linux one can do it easily by mounting the ISO on a new partition and asking GRUB to boot from it.

Anyway, found this excellent doc now, check it out:

You need the Alternate Install CD for that though.

It has many options. Hope you have a flash drive or atleast a floppy drive with a spare floppy. (See the CD Image approach)

I know he doesn't, what's your point? My given link explains methods for Windows.
